Robot that can jump like a grasshopper and roll like a ball
The first robot that can jump like a grasshopper and roll like a ball could play a key role in future space exploration.
The ‘Jollbot’ has been created by Rhodri Armour, a PhD student from the University of Bath. It’s hoped his creation, which can jump over obstacles and roll over smoother terrain, could be used for space exploration or land survey work in the future.
The ‘Jollbot’ is shaped like a spherical cage which can roll in any direction, giving it the manoeuvrability of wheels without the problem of overturning or getting stuck in potholes.
The robot is also flexible and small, weighing less than a kilogramme, meaning it’s not damaged when landing after jumping and is therefore less expensive than conventional exploration robots.
The components of the robot were made by rapid prototyping technology, similar to that used by the RepRap machine pioneered by the University, which builds parts by “printing” layers of plastic on top of each other to produce a 3D object.
