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.
Claims9
A drive system comprising:
- a first two dimensional drive system for moving a first moving body to discretionary positions in a plane by first driving means;
- and
- a second two dimensional drive system for moving a second moving body, the first two dimensional drive system being provided on the second moving body, the second two dimensional drive system moving the second moving body to discretionary positions in a plane by second driving means, a through-hole being provided in the center of the second moving body, and said first two dimensional drive system being provided in said through-hole.
