Boston Dynamics released a teaser video with SpotMini, their new small four-legged robot, and the quietest robot they designed and built. SpotMini weighs 25 kg, it is all-electric, and has a 90 minute range. The navigation is supported by stereo cameras, depth cameras, an IMU, and position/force sensors in the limbs. SpotMini has the ability to maintain balance and negotiate rough terrain.
