Abstract

The invention provides a free motion device which comprises a base, at least one driving motor and at least one connecting rod, wherein a turning joint is arranged on the base, and a motion platform is supported through the turning joint; a swing arm is arranged on the output end of the driving motor, and driven to rotate during the rotation of the driving motor; and one end of the connecting rod is movably connected at the tail end of the swing arm, the other end of the connecting rod is movably connected to the other side of the motion platform, and the motion platform is driven by the swing arm to move around the turning joint. Two driving motors, two swing arms and two connecting rods can be arranged in a preferable embodiment of the invention, the swing arms drive the corresponding connecting rods to move, and the motion platform is further driven to move back and forth or sideways around the turning joint or move along the central axis of the turning joint. The free motion device has the characteristics of small volume, succinct structure, low cost, high precision, convenience in control and defined motion mode, makes the technical progress and achieves better motion effect.

Description

technical field [0001] The invention relates to the technical field of mechanical control, in particular to a free movement device. Background technique [0002] At present, in order to realize the neck movement of various intelligent robots, the existing technical solutions are to drive the screw rod and slider with a motor or use a servo push rod or directly use a linear motor to drive the movement of the motion platform, thereby driving the neck of the robot. sports. This processing method has problems such as high cost, complex structure, difficult manufacturing, difficult control, low precision, an encoder or other sensors are required to sense the position, and it cannot be small in size, so it is not suitable for small devices. [0003] A similar technology has a two-degree-of-freedom space parallel mechanism (Chinese utility model patent application number: 200620021872.7, publication date: 2007-11-28), which includes a fixed platform, a moving platform and a branch...
