When dealing with items like car dashboards, irregularly shaped metal castings, or plumbing fixtures, achieving uniform coating coverage is challenging. Drag-and-Teach Robots offer the most flexible solution for these complex geometries.
Technology Behind the Flexibility
Drag-and-Teach (also known as lead-through programming) uses high-resolution encoders and specialized safety sensors integrated into the robot arm's joints. When the safety-release button is held, the operator can physically move the arm.
Trajectory Recording: The robot records every spatial coordinate, velocity vector, and tool orientation (pitch, yaw, roll) with high fidelity.
Automatic Path Optimization: The integrated control system then smooths out the human "jitters" and automatically optimizes the path for continuous, smooth robot motion at optimal speed, ensuring no missed spots (holidays) or excessive buildup.
This process is vital for industries like aerospace and heavy machinery, where complex components require multi-angle spraying to ensure protection and structural integrity. Drag-and-Teach is faster, more accurate, and less prone to errors than manual programming for 3D surfaces.
