5. Moving the Robot Arm with CPRog
5.1 Introduction
The CPRog programming environment allows to control and program the Mover
robot. Both online and offline working is possible.
Pic. 7: Programmoberfläche von CPRog
In the upper area the three ribbons “Scene”, “Motion” and “Programming” provide
access to the main functionalities.
On the left corner information on the robots current state are provided.
On the lower side four sections are found:
•„Log Message“: Messages regarding the programs state
•„Info Center“: Shows joint values, the Cartesian position and the motor
currents
•„Jog“: Buttons to move the robot
•„Input / Output“: View and set digital IOs

18
5.2 Navigation with the Mouse
A 3 button mouse is recommended to navigate in the CPRog 3D environment:
•Left button: Selection of robots and other objects
•Middle button: Navigation in the scnee
oRotate: drag the mouse while holding the middle button
oPan: drag the mouse while holding the middle button and pressing
down the CTRL-key
oZoom: Drag the mouse while holding the middle button and pressing
down the SHIFT-key (zooms to the center of the scene), or turn the
mouse wheel (zooms to the current cursor position)
•Right button: Opens the context menu
Alternatively the function of the left mouse button can be changed in the upper
menu area at Scene/Navigation. Possibilities are Selection, Rotation, Panning or
Zooming.
5.3 Moving the Robot
The robot can be moved (or “jogged”) manually, as long as no program is running. The
main elements are the button to connect the joypad, the checkbox to choose the
motion type and the override.
Pic. 8: Elements to jog the robot
When pressing the joystick button CPRog connects with a joypad. The device must
have the type “Joystick” or “Gamepad”. Further information are provided in the log
window.
The „Joint“ mode allows to turn the single robot axis from A1 to A4. In “Cartesian”
mode the robot moves in straight lines following the x, y and z coordinate axis. The

19
rotation is defined with the B commands. In „Cartesian Tool” mode the robot moves
aligned to the current tool coordinate system.
The override scales the motion speed between 0 and 100%.
Pic. 9: Buttons to jog the robot in cartesian mode. In joint mode the buttons change to the axis A1 to A4.
While jogging in cartesian mode virtual walls can be switched on to limit the motion
and thereby avoiding e.g. collisions. See section 7 for details.
When the virtual walls are active the robots blocks further motions and
generates warning sounds when leaving the allowed area. These
restrictions do not hold in joint mode.
The most convenient way to move the robot is with a connected joypad, the picture
below shows the assignment of keys.
Pic. 10: Assignment of keys for the joypad. Upper markings for Cartesian mode, lower for joint mode.
Pressing X opens or closes the gripper, pressing A records a linear motion to the
current position and, if necessary, a gripper command.

5.4 Connect with the Hardware
The real robot can be controlled in the same way as the simulated one, only the
hardware has to be connected before: connect, reset errors and enable motors.
Prerequisites are that the robot is connected via the USB-CAN adapter and the
robots supply is running (plugged in, switched on and emergency button released).
Pic. 11: Buttons to connect to the hardware, reset the errors and enable the motors
Step 1: Connect with the hardware. This step initializes the USB-CAN
interface.
The LED on the left side of CPRog changes color from grey to red.
Below the LED several error messages are displayed.
Step 2: Reset the errors. This button resets the error memory of the joint
module controller in the robot. The joint values are copied from the
real robot to the simulation environment.
The 3D visualization of the robot has to match the current pose
of the real robot now. This has to be verified every time the
errors are reset!
The LED stays red. The error messages clear, only “Motors not
enabled“ remaining.
If further error messages remain visible try again and see section
9.3 for possible approaches.
Step 3: Enable the motors. Now the robot can be jogged as described
above.
The LED is green now.
