← TechnologyWhich outcome occurs when the inverse kinematic solution for a robotic arm positioning a weld torch near its joint limits becomes multi-valued?
A)Oscillation near the target pose✓
B)Motor overheating due to saturation
C)Accurate, smooth path trajectory
D)Consistent, repeatable weld deposits
💡 Explanation
Oscillation results because the **control system hunts** between multiple mathematically valid solutions, rather than converging smoothly; this is because the physical limitations prevent a single solution. Therefore, oscillation occurs, rather than accurate or repeatable motion in a restricted workspace.
