An object gripping device for removing and installing bulbs and other
objects. The device has around its circumference three or more vertical
gripping posts. The device uses a sun gear and planetary gears to
transmit the user's twisting motion to a gripping force applied equally
around the object's circumference. Furthermore, the gearing ratio can be
adjusted to create more or less leverage or gripping force applied to the
bulb or object. The device could also be applied to gripping any object
that is semi-cylindrical in shape. For instance, a robot can use the
invented gear system to pick up or grip objects in a factory, laboratory,
hospital, space exploration or home setting. Instead of a handle used to
rotate the sun gear a drive shaft can be attached. An electric motor, a
gas or diesel engine, a hydraulic power pack can rotate the drive shaft.
