Is it true that jittery arm movement can occur if one If statement turns on the motor and another Else statement turns it off?

The statement is true because jittery arm movement in robotics often results from rapid switching of motor commands, such as when one If statement activates the motor while an Else statement deactivates it. If these commands are evaluated continuously and in quick succession, the motor may frequently oscillate between being on and off. This rapid toggling does not allow for smooth movement, leading to erratic or jittery behavior.

In a well-structured program, conditions for motor control should be carefully managed to create smooth transitions and avoid conflicting commands that can cause such instability. Proper implementation of timing or smoothing algorithms is essential to achieve steady motor control and prevent jittery movement that might arise from conflicting commands in consecutive conditional statements.
