Control Iran Introduces Walking Humanoid Soorena Robot

Iranian President Mahmoud Ahmadinejad unveiled a new Asimo-likerobot, which they intend to use in “sensitive jobs,” according togovernment newspapers. The report did not elaborate what the robot cando apart from dragging its feet across the floor.
Soorena-2, which was named after an ancient Persian warrior,measures 1.45 meters (4 feet 9 inches) in height and weighs 45kilograms (almost 100 pounds). It was an updated creation by therobotics team at Tehran University after its predecessor was introducedtwo years ago.
Another news reports that the Soorena-2 will eventually get visionand speech modules. The robot is part of a number of scientificprojects Iran has been researching, from cloning to stem cell researchto satellite technology.

A new Iranian humanoid robot called Soorena-2 has been designedby developed by 20 researchers and engineers from the University ofTehran to be used to conduct what are being called "sensitive jobs".What these jobs actually are we don’t know. The President MahmoudAhmadinejad just recently showed off this 4.7-foot walking robot to theworld. Soorena’s, who’s been named after an ancient Persian warrior,weighs in at 99 pounds and is capable of 12 foot movements, eight handmovement and the two for the head. We still don’t know exactly whatSoorena-2 is capable of, or is just one of those technologicaladvancements one likes to show off.

Control I, Robot' Will Blow Your Circuits

Get ready for all your circuits to be blown by "I, Robot," an adrenaline rush of a movie that actually excites your mind as it excites your senses.
Debra Scott Columnist Graphic In 1950, Issac Asimov -- one of the most famous, inventive and humanistic writers of science fiction -- set down the Three Laws of Robotics in his series of short stories, "I, Robot."1. A robot may not injure a human or, through inaction, allow a human to come to harm.
2. A robot must obey orders given to it by a human, except where it would conflict with the first law.
3. A robot must protect itself, as long as that protection does not violate either the first or second law.
I,Robot: CU Robot Ever since Asimov first wrote those words, many films about robots have used his laws as a blueprint and then theorized what would happen if a robot started to evolve and deviate from its hardwired programming."I, Robot," the movie, takes that premise and then leaves the rest of the robot movies in the dust with its involving murder mystery plot. "I, Robot" has a challenging, complex story structure, characters whose pasts fit together like a jigsaw puzzle and a comforting meld of the familiar and the futuristic in its Chicago 2035 setting. Two characters were taken from Asimov's stories -- robotics pioneer Dr. Alfred Lanning (James Cromwell) and a younger version of Dr. Susan Calvin (Bridget Moynahan), who specializes in the psyches of robots.I, Robot: Will In Robots Will Smith plays Det. Del Spooner (who is not a character in Asimov's stories), just about the only cop on the police force who doesn't believe robots are completely harmless -- an attitude that doesn't play well with his boss, Lt. John Bergin (Chi McBride).On the eve of a major rollout of the next generation of robots -- the NS-5's -- Lanning apparently commits suicide and leave behind a holographic message for Spooner. As Spooner pursues breadcrumbs of information, his investigation pushes him closer to the realization that his worst fears could be closer to the truth than anyone could ever imagine.I, Robot: Robot With LeadsSmith is absolutely spectacular as the haunted detective. His pumped-up body from "Ali" is still intact, but so is the wit, sensitivity and emotion he has revealed in his other films. Everything he has done has culminated in this mysteriously complex character.At times, the stunts are a little too far-fetched for any human to make believable, but who cares? It's cool, and so are the almost translucent-faced robots -- one of whom, Sonny, is almost irresistable with its childlike curiosity and human-like need for approval. But can it be trusted?Moynahan does an adequate job with the limited role she has been given, playing the robot-believer to Smith's robot-doubter. But this movie is really about Spooner and the robots.Asimov devotees should know that that the movie only takes ideas and characters from the book and those ideas are combined with a previously written script titled "Hardwired."Is it possible that robots could actually evolve to the point where they could come up with their own interpretations of the 3 Laws, or is that just an invention of screenwriters? "I, Robot" is a provocative, exhilarating peek into an unsure future that serves as sobering warning against letting technology take too much control over our lives.

Control To make a robot which can follow a white strip on black background and can extinguish fire on its way .

line follower robot
Design Specifications 
1. For proper functioning of the robot needs a voltage supply of about 5.3V and current about 0.7A.
2. The robot should be able to distinguish between the white and the black surface.
3. If the black surface suddenly ends, the robot should keep on moving in the direction it last moved
until the black line is again there.
4. It should stop and extinguish fire and restart only after making sure that the fire has been
extinguished.
5. This could not be run using the dry cells because of the current requirement.


Principle
The basic principle used is the difference in reflection of light from a white surface
and a dark surface .This could be sensed using two LDR's. The two inputs would be fed to two different
comparator whose comparing voltage is set using the potentiometer .When the light is reflected by the black
surface the resistance of LDR is high, hence the voltage is high and vice versa .The current flowing through
the output of comparator is very low to drive the motor .Thus ,a Darlington pair is applied to the output of
the op-amp .This output could be used to run the H-bridge circuit which can rotate the motors in both the
directions. It would continue moving in the line it was last moving if there is no line.It can navigate through
almost all turns.
If a flame comes in the way the third LDR mounted on the top will detect it and stop the motors of tyres
and startthe fan. When the fire extinguishes,fan stops and the motor starts again and it continues in same
direction.


Working of the Robot



The circuit implemented consists mainly of two different sub-circuits.
The first part comprises of making the robot follow a black strip. This was done using a comparator
circuit using the LDR whose reference voltage was fixed using the potentiometer. This was based on the
phenomenon that the resistance of the LDR decreases as the intensity of light falling on it increases. In our
case, the light reflected from the white surface is more than that from the black surface. Therefore, the
voltage in positive terminal of the comparator remains high as long as the robot is moving on white surface.
If the black surface come under one of the two LDR.s the motor corresponding to that LDR stops, the other making
it move away from the black line. But as the other LDR crosses the black line, its motor stops, the other
forcing it in other direction, resulting in its following the black line. Thus ,the output voltage of the Op-Amp
has been varied according to the need,but the current flowing through the output of Op-Amp is in some mA .Thus
there was need for current amplification. The Darlington .pair was used for the same. The resistance of the motor
was 5-10ohms,thus source follower circuit was used.
The second part comprised of using LDR.s and IR-receivers to detect flame .The dual Op-Amp LM358
was used for the same. The two comparator circuits were used .For LDR, the working was same, but for IR receiver
the voltage and not the resistance vary according to the intensity of light. Thus the two ends of IR-receiver
were connected to ground and positive terminal of the comparator .The output of these two were ORed and given to
a monostable 555 timer with time period of 4 sec.555 was used because when the robot sees the fire ,the fan
starts and the motors stop but when fan starts the intensity of light decreases and hence the two motors start
again and there is a chance that the motor starts before the fire is extinguished .The 555 helps in generating a
high pulse of about 4 seconds which will remain high and will not depend on the intensity of light for the same
duration .Thus , this will make sure that the fire is extinguished before moving ahead. Once the fire is
extinguished it will retain its original motion.

Application
1. The robot can be used as a guider to guide the visitors from the entrance to the main office .
2. It can help doctors to carry the medicines from one ward to another .
3. The main purpose is to rescue the people by extinguishing fire in a building .

Hexapod Robot IIII

Six-Legged Autonomous Mobile Robot

This six-legged mobile robot was a research platform I built to
investigate reactive robotic architectures. The work won the
Third Place Grand Award at the Intel International Science and
Engineering Fair. The robot had over 2,000 components, 21 motors,
and 10 processors and was built during my senior year in high school.
The robot is very similar in design to Attila and Hannibal, designed
and built by Colin Angle and Rod Brooks at the MIT AI Lab.
This project was completed in May, 1992.

3D Modelling for beginners : Hexapod Robot



Here is a step by step design guide which will help you from
next time convert your drawings or ideas into 3D models
which are a better representation and also good to look .
For the purpose of explaining the use we have chosen to
build a model of a Hexapod . So if you can use ms paint
you can do this .

LARA



I eventually decided upon a design whereby the 6 legs were
divided into three pairs, with each pair being joined by top and
bottom beams. The legs were sat on ball-bearing thrust races
to reduce friction and allow the robot to turn easier.

Hexapod Robot2


The hexapod robot developed by the Illinois hexapod group is
modeled after the American cockroach, Periplaneta americana.
We selected this insect as a model because of its extraordinary
speed and agility and because the structure and physiology of
this insect are reasonably well known. The body of the robot measures
58 cm by 14 cm by 23 cm length, width, and height. It has an
additional 15 cm ground clearance when standing. The legs,
projecting laterally and to the front, add about 38 cm to the
width and 18 cm to the length. The robot weighs approximately
11 kg, most of the weight being in the valves that control the
pneumatic actuators. The physical dimensions of the robot body
and legs are generally between 12 and 17 times the size of the
comparable dimensions of the cockroach. The robot, however,
is considerably heavier in relation to its size due to the weight
of the valves.

Hexapod Robot III

MHEX II Walking Hexapod

Mhex II is an omnidirectional hexapod (6 legged) walking robot.
Each leg has 3 motors which allow the feet to be placed
anywhere in 3D space within mechanical limits. Unlike my first
hexapod robot (MHEX), this configuration allows the robot
to walk in any direction keeping it's feet fixed at a point on
ground without slipping.
http://mikael.geekland.org/

An 18-DOF hexapod robot developed at the University of Florence



An 18-DOF hexapod robot was complete designed and
developed at the University of Florence by Andrea Foschi in
2005. It was later tamed by Marco Natalini and Alessandro
Mambelli using Evidence Srl's FLEX Light board and ERIKA
kernel. The main purpose for adopting FLEX is due
to its low-cost development kit that permits easy addition
of features i.e. Sensors and behaviour. Since then, a number
of students have worked on this hexapod. The future version
would use the FLEX Full board.
http://www.evidence.eu.com/content/view/261/266/

Hexapod - Build Blog



Our design for the first hexapod is simple. It is supposed
to be a prototype for a more complex robot that we will
build this fall. The design includes three servos per leg.
One servo will rotate the leg while the other two perform
the functions of a hip and a knee.



Stiquito is a small, inexpensive hexapod (i.e., six-legged) robot.
Universities, high schools, and hobbyists have used
it since 1992. Stiquito is unique not only because it is so
inexpensive but also because its applications are almost limitless.
The propulsion in these robots is nitinol, an alloy actuator wire
that expands and contracts, roughly emulating the operation
of a muscle. The application of heat causes a crystalline
structure change in the wire. Nitinol contracts when heated
and returns to its original size and shape when cooled.

Hexapod Robot II

Robot II

Robot II is a hexapod with three active, revolute degrees of
freedom (DOF) and one spring-loaded, translational DOF per leg.
Each active DOF is powered by a separate 6 Watt DC motor
with an integral transmission. The sensing of joint position is
accomplished by a rotary potentiometer attached to each joint.
Foot forces are monitored by load cells mounted on the tibia
segments. The structure of the body is composed of
lightweight aircraft plywood, balsa and aluminum.

The SIL06 Walking Robot


The SILO6 is a hexapod designed as the mobile platform of the DYLEMA project
intended to configure a system for detection and location of antipersonnel land mines.
Walking robots are intrinsically slow machines, and machine speed
is well known to depend theoretically on the number of legs the
machine has. Therefore, a hexapod can achieve higher speed
than a quadruped, and a hexapod achieves its highest speed
when using a wave gait with a duty factor of β = 1/2, that is, using
alternating tripods. Although stability is not optimum when using
alternating tripods, a hexapod configuration has been chosen just
to try to increase the machine’s speed. The walking-robot
development is based on certain subsystems developed for
the
SILO-4 walking robot. The SILO4 is a quadruped robot
developed for basic research activities and educational purposes.
For this reason, this new walking robot is named SILO-6,
referring to its six legs.

Sprawlita


Sprawlita is a Shape Deposition Manufactured platform with six legs of 2 (actuated) DOF each. Based on the Sprawl 1.0 and Mini-Sprawl prototypes, it is a platform to test ideas about locomotion schemes, leg design and leg arrangement and to build compliant leg structures using SDM. The size is the same scale as Mini-Sprawl, with slightly more mass (270g vs. 250g) and less stiff compliant hip joints with only one (intended) degree of freedom.

BILL-Ant Series Robots



The Biologically-Inspired Legged Locomotion Ant (BILL-Ant) is an 18-DOF hexapod with six passive DOF feet for force sensing, a 3-DOF neck and actuated mandibles with force sensing pincer plates (28-DOF total). The robot uses force Sensors in the feet and pincers to actively comply with its environment and respond to external pertubations.

Hexapod Robot I

Mike Smyth's Hexapod Robot


This is my autonomous hexapod robot that I built a few years ago.
It uses 12 R/C servos for actuators. The 6 that raise and lower
the legs are Hobbico CS-72 1/4 scale and the 6 that move the legs
forward and backward are several brands of standard 1/10
scale servos
http://home.ctlnet.com/~robotguy67/hexapod/hexapod.htm


Robot III



a hexapod with kinematics based on studies of the cockroach
Blaberus discoidalis performed in the Ritzmann Lab in the
Biology Department at CWRU. It has a total of 24 degrees of freedom
with five for each front leg, four for the middle legs and three for the rear
legs. The robot is pneumatically actuated using off the shelf cylinders and
blocks of three-way pneumatic valves. Pulse width modulation of the
valves is implemented for variable position control of the cylinders.
The structure of the robot is machined from high grade aluminum alloys.
http://biorobots.cwru.edu/projects/robot3/robot3.htm


Bio-Robotic Choreography





The 6-legged robot will use a pentagraph mechanism where the
movement of the foot is mirrored by the joint at opposite end. The
effect is that the robot is hanging from a virtual pendulum in the sky.
This will help the robot to stay on it's feet. Stationary it will be nearly
5 metres across and measure 2 metres from knee to foot.
The designers are hoping to limit the weight to less than 250 kgs.

Rhex

RHex is a small, power and computationally autonomous hexapod
robot with passively compliant legs. Its basic design incorporates
only one actuator per leg, capable of achieving fast (~2.5m/s)
and robust locomotion over complex outdoor terrain. As a result
of the minimal use of exteroceptive sensing, most of its behaviors
are task-level open loop, driven by an internal clock. These basic
behaviors rely on a human operator for more complicated
tasks such as navigation.

Robotic Gripper 2

pneumatic gripper


A gripper was designed for transplanting. The gripper seedlings
grasping is composed of a pneumatic piston which actuates
two parallel hinged jaws that perform a scissors type movement,
which cause the jaws to grasp the plant in between. The size
and shape of the gripper was adapted to fit trays with different
plant cells sizes.

http://old.agri.gov.il/AGEN/Reports/AgriculturalRobot.html




slider gripper


This is the first of six soft tissue grippers. The gripper, thanks to two
suction cups, can pick and place large portions of fabric.
The distance between the two suction cups can be adjusted to
better fit the fabric size.

dimec.unige.it/PMAR/pages/research/robot

The 3-Jaw Parallel Gripper


The 3-Jaw Parallel Gripper is ideal for applications requiring three
points of contact, positive pick and place, and the flexibility of stroke.
It offers self-centering of parts and a high clamping force for
rapid part transfer and part gripping during grinding or de-burring, etc

Robotic Gripper 1

A parallel jaw gripper


A parallel jaw gripper A parallel jaw gripper was developed for the
robotic arm for pick and place operations. To maintain the jaws
of the gripper parallel to each other, they were connected through
a parallel mechanism of links. A linear actuator actuates the gripper.
A CAD model of the gripper mechanism is shown on the
right. The mechanism simulation was done in Idea8 mechanism
solver.

http://www.cs.cmu.edu/~amampett/pastProjects.html

Robotic Gripper Sizing


The force that a robotic gripper applies to a part is typically used by
engineers to select grippers. While gripper force is a first order
consideration, the torque that is experienced by the gripper is equally
as critical and, unfortunately, usually only addressed in a cursory
manner. In some cases the torque is addressed via the gripper
manufacturer supplying jaw length vs. force charts. These gripper
charts are helpful but are only useful in low G-force applications
and provide rough guidance at best. The result of this situation is
that “rookie” gripper application engineers end up with dropped
parts and “old hands” end up with grippers far larger and more
expensive than required. Before we start let's look at some of the
lore that is wrong!
http://www.grippers.com/size.htm

Rotational gripper



The 1 DoF gripper is the end effector of a parallel robot for
high speed assembly tasks. The gripper is mounted on a triangular
plate. The parallel architecture of the robot drives the plate
translation. An actuator rotates the whole robot (instead of the
plate itself) to allow the gripper rotation around an axis normal
to the plate; this solution minimizes the inertia of the end-effector.

2 wheel robot turns

Robot wheels have very little, if any, sideways motion
(assuming that the center of gravity of the robot is close
to the two wheels). The circle in the front of the robot is
a skid of some soft (this is any smooth piece of plastic,
such as a ping-pong ball or a bottle cap). Because this
skid is smooth, it doesn’t mind making the large sideways
motion, and the robot will turn easily.


We use two step motor and one ping-pong ball

FM Radio project


Here we will explore the wonderful world of radio. Now we will start by making L1 the tuning coil of this radio. You will need 22 gauge hookup wire and a metal bolt, 1/4 inch in diameter. Start by striping the insulation off of a 1 foot long piece of wire. Then rap it in the groves of the 1/4 inch bolt 6 times and cut off the excess wire. Leave the bolt in the coil because turning the bolt in and out of the coil tunes the radio.


The antenna is a 30 inch long piece of 22 gauge hookup wire and the mic is a condenser microphone. I have tested this circuit up to 1000ft!!! line of site
and can probably go even farther with some minor adjustments. You can receive the signal on any FM radio. If you have any questions email me at (ericgoodchild@yahoo.com)
