WidowX Robot Arm Specs (Video)Here's a robot video that I found interesting:
http://www.trossenrobotics.com/widowxrobotarm The WidowX Robot Arm is Interbotix Labs' entry level arm offering for the MX series of DYNAMIXEL Servos.The MX series actuators provide a full 360 degree freedom of movement in the base, ultra-high resolution of 4096 positions, user-definable PID parameters, and extremely smooth interpolation. The hefty MX-64 shoulder servo gives the WidowX very strong lifting strength in a slim frame. If you are looking for medium lifting strength and desire smooth control, high accuracy and repeatability the WidowX is a great mid-level arm choice. A rugged ABS boxed frame design and 14cm diameter ball bearing rotational base ensures maximum rigidity and accuracy. Optional wrist rotate allows for up to 5 degrees of freedom, along with a custom designed parallel gripper for high precision and maximum gripping strength. The WidowX Robot Arm has up to a 41cm horizontal reach and 55cm of vertical reach. At a 10cm reach it can lift up to 800g, and at 30cm up to 400g. The gripper itself has a rated holding strength of up to 500g, while the wrist itself can lift up to 500g horizontally. (400g if using wrist rotate). Dynamixels support up to 360 degrees of motion, which results in an extraordinary range of motion and reach on the WidowX . Temperature monitoring, positional feedback, as well as voltage levels, load, and compliance settings are user accessible as well. The onboard Arbotix Robocontroller can be programmed using the Arduino IDE or custom firmware, providing 8 digital and analog IOs, Xbee wireless or USB connectivity, and a powerful ATMega644p capable of handling Inverse Kinematics code onboard.
