Claims
- 1. A robot comprising:
- a motor chamber;
- first and second arm member assemblies, each supported by the motor chamber at a first end thereof for circumferential movement about a common axis;
- the first and second arm member assemblies each having a second end coupled to a common robot element; and
- a drive mechanism mounted in the motor chamber, the drive mechanism having drive members, each coupled to a respective one of the first and second arm member assemblies to controllably move the first ends of the first and second arm assemblies:
- i) in a same circumferential direction to cause the common robot element to revolve around the common axis, and
- ii) in opposite circumferential direction to cause the common robot element to move along a linear path perpendicular to the common axis.
- 2. A robot comprising:
- a robot chamber;
- a motor chamber comprising a side wall structure extending within the confines of the robot chamber and being in an airtight relation in respect to the robot chamber;
- first and second arm member assemblies, each supported at a first end thereof by the side wall structure of the motor chamber within the robot chamber for circumferential movement about a common axis;
- the first and second arm member assemblies each having a second end coupled to a common robot element within the robot chamber; and
- a drive mechanism mounted within the motor chamber and having drive members, each coupled through the side wall structure of the motor chamber to a respective one of the first and second arm member assemblies to controllably move the first ends of the first and second arm assemblies:
- i) in a same circumferential direction to cause the common robot element to revolve around the common axis, and
- ii) in opposite circumferential direction to cause the common robot element to move along a linear path perpendicular to the common axis.
- 3. A robot comprising:
- a robot chamber;
- a motor chamber comprising a wall structure extending within the confines of the robot chamber and being in an airtight relation in respect to the robot chamber;
- first and second arm member assemblies within the robot chamber, each supported at a first end thereof by the motor chamber for circumferential movement about a common axis;
- the first and second arm member assemblies each having a second end coupled to a common robot element within the robot chamber; and
- a drive mechanism mounted within the motor chamber and magnetically coupled through the wall structure of the motor chamber to the first and second arm member assemblies to controllably, selectively move the first ends of the first and second arm assemblies:
- i) to cause the common robot element to revolve within the robot chamber, and
- ii) to cause the common robot element to move in a generally linear path within the robot chamber.
