  • Patent number: 11787042
    Abstract: A transport apparatus including a drive with a drive axis and a first arm connected to the drive. The first arm includes a first link, a second link and an end effector connected in series with the drive. The end effector includes a substrate support section and a leg connecting the substrate support section to a wrist joint of the end effector with the second link. The leg has a first section connected to the wrist joint, a second section connected to the substrate support section, and a bend portion between the first and second sections such that the first and second sections are angled or offset relative to each other. Connection of the leg to the second link at the wrist joint is offset relative to a centerline of the substrate support section and offset relative to the drive axis.
