Jumping Robot 2

Grasshoppper
Grasshoppper "robot" sets new high-jump record
While it doesn't exactly boast all that many robot-like characteristics,
this grasshopper-inspired bot from the Swiss Federal Institute of
Technology is apparently enough of one to lay claim to the robot
high-jump record, which it was able to capture handily by jumping
27 times its own height. That was done with the aid of a motor
originally designed to power the vibration unit of a pager which,
in this case, winds up two metal springs that eventually release
and spring the 5-centimeter tall bot into the air.

Jumping robot makes light work of stairs

Kim's team developed an ultra-lightweight version of an old technology:

the pneumatic ram. Powered by compressed air stored in two 2-litre
plastic bottles, the ram - an aluminium cylinder - is fired to launch
the robot to the required height.
To determine how much compressed air is needed for the jump,
an onboard processor first calculates how fast the robot is travelling,
using information from its 25-centimetre-diameter wheels. It also
works out the distance to the obstacle and its height, using
stereoscopic cameras and ultrasound Sensors . The processor
uses this information to calculate the jump, then sends a signal to
a solenoid valve that squirts high-pressure air into the ram for
the right length of time.

“Jollbot” Jumping robots for space exploration

According to a team of engineers at the University of Bath, “jumping is
a good way to move over rough terrain, and is considerably easier to
design than walking.” PhysOrg.com reports that this is why they’ve
designed two jumping robots inspired by animals. They think that
their two new robots, Jollbot and Glumper, will help astronauts to during
future space missions. As one researcher said, “the cost per
kilogram of launching something into space is very large, so jumping
robots, which are likely to be light in weight to maximize
their own performance, are ideally suited from that perspective.”
Of course, such robots would also be useful to explore any
other places involving traversing rough terrains such as volcanoes.

Jumping Robot 1

AirHopper
we will develop the jumping locomotion robot in this research.
This jumping robot can move around the disaster areas where there
are many high steps and obstacles that cannot overcome previous
walking robot, shown in Fig. 1. This developed jumping robot has
both high terrain adaptability and mobility.

Jumping Robot Prototype at Stanford

During the fabrication of the prototype we had to take into account
several restrictions on the weight and room of the components.
This constraints were imposed by the presence of the flight phase
in the jump.

The robot has two parallel frames, on the right and left hand side,
which are used to keep the motor, the cam shaft and the legs in
place (see picture). In this way it is easy to assembly and
dis-assembly the robot, and the cam and the legs have room to
rotate in the inner part of the robot. Shafts rigidly connecting
the two parallel frames keeps the whole robot firmly resistant
to impacts occurring at every step. This initially was one of
the main problem in making the prototype work, together
with the friction forces

Micro-Cricket Series Robots

Biomimetic research at Case Western Reserve University

Our cricket microrobot is being developed by an interdisciplinary
team of faculty and students as part of the DARPA Distributed
Robotics (DR) program. A "micro-robot" is no larger than
5 cm in any dimension. Our robot will locomote by both walking
and jumping and its design is based upon crickets.
