Robot Arm Collision Detection
Collision detection in the robot arm detects unexpected forces by motor current analysis and prevents mechanical damage on impact.
Physico-Chemical Working Principle
Collision detection monitors the current flow at the robot's joint motors. A sudden increase in current indicates an unexpected force or impact.
Metallurgical Relevance & Risks in Welding
If mechanical damage occurs, the joints and their components can be damaged, leading to robot failure. This can extend production times and increase repair costs.
Workshop Practice & Action Instructions
To check collision detection, perform the following steps:
1. Start the robot arm and move it slowly in different directions.
2. Observe the current values at the joint motors on a display or monitoring camera.
3. If a sudden increase in current is detected, stop the movement immediately and inspect the joints for damage.
4. If damage is suspected, contact service or perform a repair.
