An apparatus including a robot drive having motors and coaxial drive shafts connected to the motors; and a robot arm connected to the robot drive. The robot arm includes two upper arms, a first set of forearms connected to a first one of the upper arms, a second set of forearms connected to a second one of the upper arms and end effectors connected to respective ones of the forearms. The first and second upper arms are connected to respective first and second ones of the coaxial drive shafts. The first set of the forearms is mounted on the first upper arm and connected to a third one of the coaxial drive shafts by respective first and second drive belt assemblies. The second set of the forearms is mounted to the second upper arm and connected to a fourth one of the coaxial drive shafts by respective third and fourth drive belt assemblies.

A method including, based upon a desired path of a reference point from a start position to an end position, where the reference point is on an end effector on a robot arm, determine an included angle that corresponds to the start position and the end position, calculating a trajectory in radial coordinates of the reference point on the end effector at least partially based upon the included angles; calculating corresponding angular coordinates of the reference point on the end effector, based on the calculated radial coordinates, so that the reference point follows the desired path; using a modified formulation of inverse kinematics, converting the radial and angular coordinates supplemented with the included angles of the trajectory and corresponding angular velocity and acceleration of the end effector to form motion setpoints for the robot arm; and controlling the motors of the robot drive.

An apparatus including a linear transport configured to move in a transport chamber along a straight path; a robot connected to the linear transport, where the robot includes a robot drive and a robot arm connected to the robot drive, where the robot arm is a dual-link arm having a first link connected to the robot drive and a second link forming an end effector for supporting a substrate thereon; a controller connected to the linear transport and to the robot drive, where the controller is configured to provide movement of the linear transport along the straight path at a same time as extension and retraction of the dual-link arm to thereby move the end effector into or out of a substrate process chamber or a substrate holding area while both the linear transport and the dual-link arm are moving.

摘要:
A substrate transport arm including a first link; a second link rotatably connected to the first link; a third link rotatably connected to the second link at a wrist joint; and a mechanical transmission having a pulley. The third link includes an end effector configured to support a substrate thereon. The mechanical transmission is connected to the third link to control rotation of the third link on the second link. The mechanical transmission is configured to control rotation of the third link as a function of an angle between the first and second links such that, as the first and second links are rotated relative to each other, the wrist joint follows a wrist path which includes a curved portion, and where a center of the substrate supported on the end effector is moved along a substantially straight substrate path as the wrist joint follows the curved portion.

An apparatus including a controller; a robot drive; a robot arm connected to the robot drive, where the robot arm has links including an upper arm, a first forearm connected to a first end of the upper arm, a second forearm connected to a second opposite end of the upper arm, a first end effector connected to the first forearm and a second end effector connected to the second forearm; and a transmission connecting the robot drive to the first and second forearms and the first and second end effectors. The transmission is configured to rotate the first and second forearms relative to the upper arm and rotate the first and second end effectors on their respective first and second forearms. The upper arm is substantially rigid and movement of the upper arm by the robot drive moves both the first and second forearms in opposite directions.
