Typically, four-legged robots require an arm to open doors or pick up objects, but this robotic canine can perform these tasks using its front leg.

The research team at ETH Zurich in Switzerland, led by Philippe Arm, employed a machine learning model to teach the robotic dog how to handle different situations using its leg while standing or moving with its other three legs.

Arm points out that this development aims to improve the effectiveness of four-legged robots, which face challenges navigating through tight spaces when equipped with an additional arm. Their application in space exploration is one example of the potential benefits of this technology.
