1. A method for preventing and mitigating collisions between a dipper and tracks of a mining machine, the method comprising:
receiving dipper position data indicative of a position of the dipper;
setting, based on the dipper position data, a motion command limit for a dipper motion, the dipper motion being selected from a group of a swing motion, a crowd motion, and a hoist motion;
comparing a dipper motion command input to the motion command limit;
controlling the dipper motion according to a first dipper motion command when the dipper motion command input is less than the motion command limit; and
generating a second dipper motion command and controlling the dipper motion according to the second dipper motion command when the dipper motion command input exceeds the motion command limit.
