BUTTON MODE

In this mode, you can control the Robot Arm through the buttons:

* BASE
* SHOULDER
* ELBOW
* WRIST
* CLAMP

Start position

At the program start, all counters are set to zero.
The starting position of the robot is now:
• Base in the center position
• Shoulder in the highest position
• Elbow in the highest position
• Wrist in the center position
• Clamps closed

If needed, you might have to bring the robot manually into 
the start position.

With this method, you can easily test the way how the robot works and 
try out more complex movements before you actually program the com-
mands.

The operating buttons clearly display which movement you are con-
trolling.You control the Robot Arm with the left and right mouse but-
ton. Please note that the arm moves in direction of the arrow that is 
displayed when the key is activated. If the arm moves in the opposite 
direction, the voltage polarity is wrong. In this case you have to reverse 
the positive and negative connections of the motor driving voltage.
