A machine-learning model worked out how to keep this robot stable on three legs while it uses one leg to open doors<\/p>\n

A robot dog can use a leg to open doors<\/a>, press buttons and pick up rucksacks while balancing on its other three legs.<\/p>\n

Four-legged robots like Spot, the star of Boston Dynamics\u2019 viral videos<\/a>, normally need an arm attached to their body to open doors or pick up objects, but this can add significant weight and make it harder for the robot to squeeze through narrow spaces.<\/p>\n

Philip Arm<\/a> at ETH Zurich in Switzerland and his colleagues used a machine-learning model to teach an off-the-shelf robotic dog to use one of its legs to perform tasks while standing still or moving with the other three legs.<\/p>\n
