setting the current point position at the tail end of the mechanical arm as A, the target point position as B, and the quotient of dividing A by 3 as A_SThe remainder is A_YThe quotient of B divided by 3 is B_SThe remainder is B_Y;

when A is_YKeeping the current arm still when = 0;

when A is_YWhen =1, the motion point position is A, A-1;

when A is_YWhen the number of the motion points is not less than 2, the motion points are A, A-1 and A-2;
