- *Abstract
-
Next-generation robotic technology is driving towards better control of agile motions. This includes a technology focus on generating enhanced peak power for jumping agility. Most leaping robots use a spring mechanism with a latch. Due to the on/off nature of latches, the result is very high-powered releases of energy which are difficult to control. To address this problem, researchers at the University of California, Berkeley, have developed a new mechanical approach using “power modulation” that allows for high amplitude, high frequency jumps without the use of latches. In one embodiment, a multi-bar linkage connected only by revolute joints is capable of minimizing impulse loading and manipulating power output while performing rotation-free jumps. The Berkeley team has demonstrated an 85 gram prototype which delivered almost four times more peak jumping power than the maximum its motor can produce. Moreover, in silico testing predicts the prototype could reach an agility levels exceeding that of the most agile animals if the actuator power is raised to 15W.
