Claim 0:
1. An overhead drill press, comprising:
an onboard controller;
a cart chassis;
a shaft connected to the cart chassis, the shaft being configured to selectively move vertically between a down position and one of a plurality of raised positions;
a turret attached to an upper portion of the shaft;
a first drill connected to a first portion of the turret and a second drill connected to a second portion of the turret;
a first motor connected to the shaft which when activated by the onboard controller causes the turret and the first and second drills to selectively rotate between different rotational positions;
a second motor configured to move the first drill vertically between a lowered position and a raised position;
a third motor configured to move the second drill vertically between a lowered position and a raised position;
a plurality of motorized drive wheels; and
a sensor suitable for measuring distance, an angular velocity sensor, said sensors configurable to report measurement data to the onboard controller;
wherein the onboard controller is configured to control the shaft to move the shaft to position the turret adjacent to a surface to be drilled, to control the second motor to raise the first drill to a drilling position of the surface to be drilled, to control the first drill to drill a hole in the surface, to control the second motor to lower the first drill away from the surface,
further wherein the onboard controller is configured with a pressure switch and a laser to control speed of movement of the shaft and the pressure the drill exerts onto a drilling surface.
