← TechnologyWhich consequence results when resolvers within a robotic arm's joint exhibit signal aliasing due to insufficient sampling?
A)Sudden joint overheating occurs
B)Erroneous position feedback is introduced✓
C)Link stiffening reduces payload capacity
D)Electromagnetic interference is generated
💡 Explanation
Erroneous position feedback occurs, because under-sampling causes the signal to be misinterpreted via **signal aliasing**. Therefore, the control system receives incorrect joint angle values, rather than accurate high resolution data which is needed for inverse kinematics
