Is there a limit to how high a robot can jump? 🤖
"Following these insights, we created a device that can jump over 30 [meters] high, to our knowledge far higher than previous[ly] engineered jumpers and over an order of magnitude higher than the best biological jumpers," they write. Their jumper, which stands just less than one foot high and weighs just more than one ounce , can launch itself 108 feet into the air, with a take-off velocity of 92 feet per second.
"The rotary motors that are commonly found in engineered robots can overcome [these limitations] by acting as a winch to provide a force over a much larger displacement without needing a larger motor, thereby increasing work density," Bergbreiter says."As long as rotary motors can continue rotating, engineered systems are instead limited by the energy density of the springs.
