Product Description of SP Series Robot Joint Actuators
SP(Servo-Planetary) series planetary robot joint module is an integrated Servo joint actuators developed and produced by Avatar Robotics. SP planetary robot joint module is a highly integrated micro-servo joint with precision planetary reducer, torque motor and professional servo drive, which forming a drive control integration. The planetary joints are connected in series through the CAN bus, the wiring is simple and easy to operate, and the failure rate of the whole robot joints is low; The planetary has small size and large torque, especially suitable for bionic robot, bionic animal, educational robot arm and other multi-joint combination application scenarios; At the same time, the integrated planetary Servo joint actuators can replace a variety of brushless motors and large torque steering gear because of its high cost performance and stable performance

Integrated servo planetary robot joint actuators adopts serial bus connection, which greatly simplifies the system routing, while the joint size is small, the energy density is large, and supports flexible position control and force feedback, which is an excellent solution for simulating robots and bionic animals. Avatar can provide whole-body joint servo motors for artificial robots, with stable performance and low cost. The planetary robot joint actuators has achieved large-scale mass production and established cooperation with a large number of simulation robot companies at home and abroad.

Installation and connection
The upper computer is connected to the joint, and the USB to CAN module needs CAN-able to connect.
Connect cables to the CAN debugger. Connect L to CAN_L, H to CAN_H, G not connect, and R dip switch 1,Dial to ON, and then connect the debugger to the joint.
24V power supply port, plug-in terminal model: XT30UPB-M, distribution terminal model:XT30U-F; 24V connects to the positive terminal of the power supply, GND connects to the negative terminal of the power supply
Communication connection between joint module and upper computer: connect with UCB_CAN connection board, connect USB turn CAN device (Canable_CandleLight) to the USB port of the computer, connect the integrated motor joint to USB ,turn CAN device on and power on.
