Claim 16:
17. A machine for roadwork, the machine comprising:
a frame;
a power source;
a milling rotor operatively connected to the power source and the frame;
a pair of side plates, the milling rotor is located between the pair of side plates, and at least one of the side plates includes a sensor configured to measure cutting depth of the machine;
an inboard ski connected to the milling rotor, the inboard ski including at least one sensor configured to detect the cutting depth of the machine;
a grade and slope system that can be turned on by an operator of the machine, the grade and slope system includes a slope controller that automatically adjusts at least one milling parameter to maintain a grade and a slope entered by the operator;
an obstacle detector which detects obstacles around an exterior of the machine; and
an obstacle detection trigger which activates an obstacle-detection response upon determining that an obstacle will contact either of the side plates, the obstacle-detection response:
raises one or both of the side plates above the milling rotor; and
directs the grade and slope system to use the at least one sensor on the inboard ski to measure the grade or slope of the machine.
