According to foreign media reports, quadruped robots that can walk may be good at climbing obstacles, but wheels are more efficient for running on smooth ground. That’s why engineers at the Federal Institute of technology in Zurich have added power wheels to their existing anymal quadruped robot. The basic acyclic version of < / P > < p > any has been around for several years. It hobbles along on four mechanical legs, able to cross uneven terrain and even climb stairs. However, if the robot simply moves along the corridor or sidewalk and the robot just rolls on wheels, its battery power will be greatly reduced. < / P > < p > when in drive mode, it only needs to gallop on these wheels at a speed of 4 meters (13 feet) per second. When it has to switch to walking gait, the on-board sensor and motion planning microcontroller will selectively control the torque of each wheel. This allows some wheels to brake and use their tires to provide grip, while others roll progressively forward or backward as needed. < / P > < p > although the Federal Institute of technology in Zurich has been experimenting with wheeled anymals since 2018, a new and improved version has recently been created and the action can be seen in the video below. The agency also showed off a wheeled biped robot earlier this year. SpaceX beat blue origin and Northrop Grumman to win a $316 million air force contract
