Now clamp a rectangular piece of card- board or plastic strip of about 40 x 10 cm between the gripper jaws as an adjustment aid so that about 1 cm protrudes. Confirm using 'Enter'! Now drive the gripper using the '+' and '-' keys until the gripper (more precisely: the longitudinal axis) is located parallel to the base plate. Confirm the position using 'Enter'. As before, the ROB3 again drives dynamically to this position, and you have the possibility for correction. When the gripper (with horizontal upper arm and vertical lower arm) has been aligned as horizontally as possible to the base plate as possible: press 'Ctrl-Enter'.
