According to reports from Fast Technology on May 20, a research team from Carnegie Mellon University in the United States has announced the development of the world’s smallest electric autonomous micro bipedal robot, “Zippy”.
This robot stands at less than 4 cm tall, and with its compact onboard battery, actuators, and control system, it can not only start autonomously, but also walk, turn, jump, and climb at a speed of 10 steps per second.
It is understood that the secret to “Zippy”‘s walking lies in: the forward shift of the center of gravity when the front legs are lifted, combined with the arc-shaped design of the front feet, allowing ample swinging space for the hind legs, thus achieving significant strides.
This ingenious mechanical structure enables its step frequency to be comparable to that of a human running at 31 km/h, setting a record for the running frequency of autonomous bipedal robots.
The research team pointed out that this micro robot can access narrow spaces that are difficult for humans and other devices to reach, making it applicable in post-disaster search and rescue, industrial inspection, and geological exploration fields.
