Robot

A pet robot shaped like an animal uses a clever leg design. Inside its body, a motor rotates a central part, and a second motor is attached to this rotating part. This second motor then connects to the robot's thigh, which is designed to partially enclose the motor, while a third motor inside the thigh moves the calf, allowing for articulated leg motion.

Why it matters: The design's compact actuator integration within the leg and torso, requiring complex internal geometries, is now more achievable. Advances in precision 3D printing and miniaturized, high-torque actuators since 2020 make this manufacturing more feasible.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateCustom mechanical joints, multiple actuators, control system.
