ViperX-250
Overview
The ViperX-250 Robot Arm belongs to the Interbotix X-Series family of arms featuring the DYNAMIXEL X-Series Smart Servo Motors. The X-Series actuators offer high torque, efficient heat dissipation and great durability all at a smaller form factor over previous DYNAMIXEL servos. The DYNAMIXEL XM540-W270 & DYNAMIXEL XM430-W350 servos offer high resolution of 4096 positions and user definable PID parameters, temperature monitoring, positional feedback, as well as voltage levels, load, and compliance settings are user accessible as well. At the heart of the ViperX-250 is the Robotis DYNAMIXEL U2D2 which enables easy access to DYNAMIXEL Wizard software as well as ROS. The ViperX-250 offers 5 degree of freedom and a full 360 degree of rotation.
