← TechnologyWhich outcome occurs when a redundant robotic arm joint lacks proper kinematic calibration?
A)Unpredictable end-effector path deviation✓
B)Increased energy consumption at the end-effector
C)Joint motor overheat from high load
D)Encoder signal drift leading to jitter
💡 Explanation
In redundant robotic arms, imperfect kinematic calibration causes misinterpretation of joint angles during inverse kinematics calculations. Because the control system cannot accurately map target positions to joint configurations, that will trigger unpredictable end-effector deviations, therefore decreasing precision, rather than the issues associated with energy, heat or separate signal errors.
