30 m is a new record for a robot. The authors stated that their development will change the approach to design
Authors of similar scientific papers often study livingcreatures to create devices that move as well and as fast as they do. But the elements that create a jump in a biological system can limit researchers.
"Living beings can only jump with suchthe amount of energy they can produce per muscle tension,” said Charles Hayo, Ph.D. Therefore, such a system is limited in the amount of energy it can give off to push off and make a jump.
The authors decided to try to increase the numberavailable energy. They decided to use motors that spin to do a lot of things. So they multiply the amount of energy that they can store in their spring. The researchers called this ability job multiplication.
Based on these findings, researchersdeveloped a jumper that is not biologically similar. The size of the spring in relation to the motor was 100 times larger than systems inspired by living things. In addition, the authors developed a new spring, aiming to maximize its energy storage per unit mass.
In their hybrid tension-compression springThe carbon fiber compression bars are compressed while the rubber bands are stretched by the tension of the line wound on a motor-driven spindle.
As a result, the device could reach speeds of up to 9 m/sec with an acceleration force of 315g. According to the study, for such structures these values are close to the permissible limit.
