A robot can lose its calibration due to several factors, including mechanical shocks, collisions, wear and tear on joints, environmental changes, and encoder malfunctions. Mechanical shocks or collisions can cause the robot's joints to shift slightly, altering the robot's kinematic parameters and resulting in positional inaccuracies. Wear and tear on the joints, particularly in the gearboxes, can introduce backlash and compliance, affecting the robot's abili....
