- Six degrees of freedom
- Support for the Robot Operating System (ROS)
- Reach of 680 millimeters
- Payload capacity of 250 grams
The WidowX 250 Mobile Robot Arm, 6DOF belongs to a new family of arms from Interbotix, featuring the DYNAMIXEL X Series Smart Servo Motors. These X Series actuators offer higher torque, more efficient heat dissipation, better durability and a smaller form factor than previous DYNAMIXEL servos. The DYNAMIXEL XM 430 W350 and DYNAMIXEL XL430 W250 servos offer a high resolution of 4096 positions and user definable PID parameters. Temperature monitoring, positional feedback, voltage levels, load and compliance settings are also user accessible. At the heart of the WidowX 250 6DOF is the Robotis DYNAMIXEL U2D2, which enables easy access to DYNAMIXEL Wizard software, as well as ROS. The WidowX 250 offers 6 degrees of freedom and a full 360 degrees of rotation.
ROS packages for Kinetic and Melodic on Ubuntu Linux 16.04 and 18.04 make it easy for users 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 show users how the core packages work.
The WidowX 250 6DOF Robot Arm has a horizontal reach of 68cm from the center of the base to the gripper, with a total span of 138cm. The working payload for the WidowX 250 6DOF arm is 250g. The working payload is the weight that 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.
