Apptronik releases humanoid robot with bespoke linear actuators [Video]

In August 2023, Apptronik released Apollo, its first commercial version of a bipedal humanoid robot. The company is no stranger to the development of legged robotics, having built multiple generations of exoskeletons for the U.S. Defense Department.

These projects helped Apptronik develop the kinematics, mechanical and electrical expertise to support the venture into bipedal robotics.

The company’s primary intellectual property is linear actuation. Apollo includes several linear actuators for its leg and arm joints. Apollo uses linear actuators for joints such as the elbow and knee, in contrast to competitors who have opted for rotary motors and gear trains.

By offering a sixth generation of motors, Apptronik has surpassed rivals like Tesla in this area. Not only does this improvement make things cheaper, but it also makes the supply chain more reliable and the manufacturing process more scalable, which is important for expanding Apollo’s uses beyond factories.
