MyActuator RMD X8-32 V4 Planetary Actuator (RS485, Single Encoder)
MyActuator RMD X8-32 V4 Planetary Actuator (RS485, Single Encoder)
🚀 Cost-optimised V4 smart joint actuator for volume builds
🔍 Product Overview
The MyActuator X8-32 is an RMD-X V4 integrated planetary joint actuator (RS485) - a complete robot joint in a single unit that packs a BLDC motor, planetary reducer, FOC driver and encoder into one module, using an RS485 bus and a single encoder to hit a lower price point for multi-joint builds where budget scales with joint count. It eliminates the need to engineer your own motor + gearbox + driver + encoder stack, which is why integrated smart actuators are the single most important building block of a modern humanoid robot.
