Patent attributes
An apparatus includes a platform configured to traverse a stationary base along a motion path; a drive coupled to the platform; and a movable arm assembly. The movable arm assembly includes a pivoting base connected to the drive, first and second linkages connected to the pivoting base, each linkage having links connected via rotary joints and each link having at least one end-effector. The platform is configured to traverse the stationary base along a motion path in two opposing directions and the drive and the movable arm assembly are configured to cause independent and simultaneous movement and transfer of substrates from at least one of a first substrate holding area, a second substrate holding area, a third substrate holding area, or a fourth substrate holding area into or from a respective substrate workstation.
