Salto-1P, the jumping robot has been made by the UC Berkeley’s Biomimetic Millisystems Lab. This jumping robot can perform some really impressive saltatorial stunts.
SALTO stands for, “Saltatorial Locomotion on Terrain Obstacles”. The project was originally launched in 2017. Salto-1P jumps up and down, back and forth like a grasshopper, and like some other animals like Kangaroo, but with enticing precision and speed.
The robot has one 14.4 cm (5.5 inch) long leg, 2 thrusters and a tail for reorientation. It can perform a maximum jump of 1.25 m and has a maximum Vertical Jumping Agility of 1.83 m/s.
This jumping robot uses a small motor, a system of linkages and gears to jump. It uses a rotating inertial tail, 2 little thrusters to stabilize, as it spends little time on the ground, so, it has to do most of the controlling in the air only (in between jumps) to land properly on the ground and to generate proper thrust for the next jump.
The two little thrusters installed control Salto-1P’s yaw and roll. When the two thrusters thrust in two different directions, the robot yaws and when both the thrusters thrust in the same direction, the robot rolls. Having the tail, gives it the capability to control itself in three dimensions, even in the mid-air, which allows it to chain together and perform multiple jumps. This ability of reorienting itself in between jumps makes Salto-1P different and better than others.
Further, modifications even allow the robot to transfer more energy to the springs so as to achieve the highest jumping ability.
Salto-1P is not the only jumping robot and there are others as well, but it does saltatorial stunts with more beauty and precision than any other.
