- Five degrees of freedom
- Support for Robot Operating System (ROS)
- Reach of 650 millimeters
- Payload of 250 grams
The WidowX 250 Robotic Arm belongs to a new family of arms from Interbotix featuring the DYNAMIXEL X Series Smart Servo Motors. The X Series actuators offer higher torque, more efficient heat dissipation, better durability, and a smaller form factor compared to previous DYNAMIXEL servos. The DYNAMIXEL XM 430 W350T and DYNAMIXEL XL430 W250T servos offer high resolution of 4096 positions and user definable PID parameters. Temperature monitoring, positional feedback, voltage levels, load, and compliance settings are all accessible to the user. At the heart of the WidowX 250 is the Robotis DYNAMIXEL U2D2, which enables easy access to DYNAMIXEL Wizard software as well as ROS. The WidowX 250 offers five degrees of freedom and a full 360 degree rotation.
ROS packages for Kinetic and Melodic on Ubuntu Linux 16.04 and 18.04 make it easy for one to get started with the WidowX 250 arm. These packages include full meshes and URDFs (including accurate inertial models for the links), a driver node that controls the physical robot arm and publishes joint states, as well as Gazebo and MoveIt support. Examples are also included to demonstrate how the core packages work.
The WidowX 250 Robot Arm has a 65cm horizontal reach from the center of the base to the gripper, with a total span of 130cm. Its working payload is 250g. Working payload is the weight which the arm should not exceed under normal working circumstances, and is measured by the arms ability to repeatedly lift an object at roughly half extension without failure. While the WidowX 250 can lift more than 250g, it is not recommended to exceed this number.
