Ah! Critical Error: Step Size 18 → Angle Must Be Divisible by 18 to Be Reachable
(Solve Navigation Bug in Robotics Path Planning Using Cryspal Angles) In robotics, especially in advanced robotic path planning and joint control systems, joint angles often depend on precise step increments. A common critical error arises when step sizes do not align with angle divisibility—specifically, when step size 18 leads to unreachable angles because a valid angle must be divisible by 18. This OS-level warning means your navigation or motion control system cannot safely reach the intended orientation, risking mechanical strain, positioning failure, or system lockout. ### What Does “Step Size 18 → Angle Must Be Divisible by 18” Mean? In robotic joint control, many systems use angular steps (e.g., in servo motors or rotational actuators) corresponding to discrete angle increments. Step size defines how many units of angular movement occur per step. If your system uses a step size of 18 degrees and expects precise angular positioning, then only angles that are exact multiples of 18° are normally reachable without overshoot, missed targets, or joint backlash.
