Robot Servo Motor | Petoi Quadruped Robots

Slim plastic-geared high-performance Robot servo motor with fast and precise actuation to meet the demanding requirements of legged robotic walking joints and head panning.

We use high-end coreless motors in the servo for instant reverse rotation and large output torque. The rated life span is longer than 100 hours of continuous walking. The output gear has a built-in stuck-protection mechanism to instantly release excessive force and then reduce the current. It helps to avoid damage to the gear system or injuries to the operator.

The Robot servo Motors are brushed, and the brush contacts will eventually wear out, so you'd need some spare servos. You may need this 10-servo set if you expect to have high usage, such as for teaching or researching quadruped walking robots.

Note that Nybble isn't compatible with these servos. If you need Nybble servos, please contact us.
