Can jump twice as high as Big Ben
Using a combination of mathematics, computer simulations and laboratory experiments, researchers have found that it can travel through obstacles several times its own size. to jump high They discovered how to design a robot with the optimal size, shape, and arrangement of parts that allows
The highest jumping robot available is its size 110 times The equivalent can reach up to 33 metres. Now researchers have discovered how to design a robot that can jump 120 meters in the air (or 200 meters on the moon). This, Big Ben It is more than twice the height of the tower.
This advance will revolutionize a variety of applications, from planetary exploration to disaster recovery to surveillance of hazardous or inaccessible areas. University of Manchester Space Robotics Research Fellow Dr John Lo“Robots have traditionally been designed to move by rolling on wheels or using legs to walk.
But jumping provides an effective way to travel where the terrain is challenging. Although jumping robots already exist, there are many major challenges in the design of these jumping machines. The most important of these is to jump high enough to overcome large and complex obstacles. “Our design will significantly increase the energy efficiency and performance of spring-driven jumping robots.”
Researchers found that traditional jumping robots often take off without fully releasing their stored spring energy, causing inefficient jumps and limiting their maximum height. They also found that they wasted energy by moving side to side or turning instead of moving upward.
New designs should focus on eliminating these undesirable movements while maintaining the necessary structural strength and rigidity. Aerospace Engineering Senior Lecturer Dr. “There were a lot of questions to be answered and decisions to be made about the shape of the robot,” says Ben Parslew. “For example, should it have legs to push off the ground like a kangaroo, or should it look more like an engineered piston with a giant spring?
Should it be a simple symmetrical shape like a diamond, or should it be something more curved and organic? Then, once we have decided on this, we need to consider the size of the robot. Small robots are light and agile, but larger robots can carry larger motors for more powerful jumps, so is the best option somewhere in the middle?
Our structural redesigns redistribute the robot’s component mass upwards and taper the structure downwards. “Lighter legs and the use of prism-shaped springs that only stretch are features that we have shown to increase the performance and, most importantly, the energy efficiency of the jumping robot.”
While the researchers have found a viable design option to significantly increase performance, their next goal is to figure out how to use the kinetic energy from its descent to control the direction of the jumps and increase the number of jumps the robot can make in a single run.
