Abstract
Combining a plurality of two dimensional drive systems, a plurality of moving bodies can be independently moved by each of the two dimensional drive systems. Therefore, tools, robot-heads, work, etc. attached to the moving bodies can be moved independently. By attaching one of the two dimensional drive systems to another, the movement of both moving bodies are composed, so that the moving body of the one attached to another can be moved compositely. Therefore, the moving body or a tool, etc. attached thereto can be moved in a complex motion.
Claims21
A drive system comprising:
- a plurality of two-dimensional drive systems connected in three dimensions, each of the two-dimensional drive systems having a frame, a body and a pair of rods connected to the body, the body and rods being within the frame such that the frame surrounds the body and rods, the rods each having ends adjacent the frame, the rods being generally perpendicular, each of the bodies being movable along one pair of rods to discretionary positions in a plane, each of the planes for the bodies being noncoincident;
- and
- driving means for driving each of the two-dimensional drive systems.
