Abstract

In one aspect of the invention, a machine for degrading a natural and/or man-made formation has picks connected to a drum of the machine and at least one accelerometer mounted to the machine adapted to measure forces acting on the machine. Electronic equipment is in communication with the at least one accelerometer and the electronic equipment has a processor adapted to determine a change in the formation based off of input from the at least one accelerometer. The electronic equipment also is in communication with a mechanism adapted to control, at least in part, a location of the drum.
