Force-controlled manual guidance
Force-controlled hand guiding enables intuitive programming of cobots by directly grabbing and leading the robot arm in 'teach-in' mode. It allows ergonomic and fast path recording without programming knowledge.
Physicochemical Working Principle
Force-guided manual guidance uses sensors that measure the force at the cobot's gripping tool. This data is transmitted to the robot system in real time and processed to control the arm's movement.
Metallurgical Relevance & Welding Risks
This technique is especially useful for welding fine or complex parts. It enables precise motion control and can improve weld seam accuracy. However, a badly adjusted force sensor can lead to inaccurate paths, which can result in failures or incomplete welds.
Shop Practice & Action Instructions
To use force-guided manual guidance successfully, sensors must be calibrated regularly. The maximum force should stay below the specified limits (e.g., 50 N). For complex tasks, it's advisable to run several 'teach-in' sessions to optimize the paths.
