Google’s Boston Dynamics, an engineering and robotics company widely known for their 240-pound robot BigDog, has developed their lightest robot yet. SpotMini weighs only 65 pounds and runs for about 90 minutes on a charge. The agile robot has been recorded in a home going up the stairs, ducking under a table, and even loading a dishwasher! SpotMini navigates using a variety of sensors.
In 2015, ten years after its release, BigDog was discontinued. The robot was modeled after a pack mule and intended for use in combat, but it was too loud for this application. SpotMini has an all-electric design replacing the liquid-powered pistons of BigDog, which makes SpotMini one of the quietest robots Boston Dynamics has ever created. However, SpotMini may be applied domestically more than in combat as it resembles a dog and proves to be helpful with household chores.
