General information

For remote access to the robot, i.e. from ROS or via a Python scrict, use the host name rt29.

Starting the robot

To power on the robot, press the green button on the control box.

After the controller computer has booted, the screen will report that the robot has changed state and needs to be initialized. To do this, press the button in the noticifation box on the screen. On the new screen, press the top Auto button until the joints reports Ready. Then hold down the Auto button until all joints report ok. Note that this will make the robot joints move, if the robot is about to collide with itself, release the auto button and move the apropriate joint(s) to avoid a collision. When all joints are 'OK', press the Ok button in the lower right corner.

To move the robot into a desired position, press either of the top two buttons, and select the Move-tap. Then move the robot by using the arrows or by holding down the Teach button and move the robot by hand.

Denavit-Hartenberg parameters

All values used for inertia and kinematics calculation can be found in the ROS Model data file.

The most important DH parameters are listed here for reference:

Denavit-Hartenberg parameters
Joint Type a α d θ Offset
1 Revolute 0.00000 π/2 0.089159 q1 0.00
2 Revolute -0.42500 0.00 0.00000 q2 -π/2
3 Revolute -0.39225 0.00 0.00000 q3 0.00
4 Revolute 0.00000 π/2 0.10915 q4 -π/2
5 Revolute 0.00000 -π/2 0.09465 q5 0.00
6 Revolute 0.00000 0.00 0.0823 q6 0.00

Gripper information
