Description

Scientists from the University of Notre Dame have taught a four-legged robot to land on its feet after falling. To solve the problem, the researchers weighed the robot's legs and trained the neural network to quickly determine the position of the device in space, detect the state of a fall, and make a decision to correct the trajectory.
One of the problems of four-legged robots is falling from a great height, after which the devices are damaged and sent for repair. The researchers noticed that nature already has a mechanism for solving this problem - cats have learned to land on their feet to minimize damage. Scientists decided to implement a similar technology for the Mini Cheetah robot.
First, the researchers conducted an experiment, collected data and found that cats swing their paws when falling in order to align their bodies in space. The legs of four-legged robots are usually made as light as possible to allow them to develop sufficient speed when moving. Therefore, it was decided to modify the design of the device. Scientists have 3D-printed shoe covers, which are filled with five-cent coins. Each leg of the robot had 532 grams of additional load.
Next, scientists trained a neural network using simulation to determine the position of a four-legged robot and make a decision in which direction to shift the weight of the legs for a correct landing. At this stage, it was important for the researchers to achieve reflex working out of the algorithm, since the speed of decision making directly affects a successful landing.
The scientists also noted that the key to improving the technology could be the development of flexible spines for robots. This design will help simulate the wriggling movements of cats, so that four-legged robots will be able to quickly change their position in space.
The Mini Cheetah robot was presented by the Biomimetic Robotics Laboratory of the Massachusetts Institute of Technology. The development is positioned as a lighter and faster competitor to robots from Boston Dynamics.
