Robotic system for automatically manipulating small objects

摘要

The robotic manipulator has an electrically activated actuator, moveable along one axis, angularly abutting a carriage which is constrained to move at right angles to the actuator axis. A piezo-electric actuator (1), driven by a variable high voltage power source (2) advances a head section which is constrained (4) to move along an axis (x) and contacts, through a linear ball bearing 5), a holding unit (6) for the object which has an amplified movement at right angles (y) to the actuator axis depending on the angle of contact ( alpha ). Actuators may be used in other directions to increase the degrees of movement an pairs of piezo-electric elements may be used to hold the objects.
