WristPushDemo

This is a ros node that uses the force torque readings for the wrist to control movement of the shoulder and elbow motors.

The node will initially extend the arm, and either halt movement or retract the arm depending on the force applied.

Dependencies: This demo depends on the ROS package MAESTRO for robot control.

• ROS Fuerte
• MAESTRO (ROS stack)

To Run

• Maestro must already be started.
• Motors must already be homed and enabled in Maestro
• Motors RSP and REP must be enabled

• run 'roslaunch wrist_demo demo.launch'
• Wait for the robot arm to extend fully
• Press Enter to calibrate low
• While pushing the wrist in the direction of the arm, press Enter to calibrate high
• Push the wrist in to move the arm inwards, and release to make the arm extend.
