Gantry robots are automation workhorses. As the big brother of the cartesian-type robot, this machine often handles the most demanding robotic applications. Gantry robots are identified by their large structures vaulting overtop the workstation. Gantry robots will have two large x-axis actuators that travel the length of the work envelope. They will have at least one y-axis actuator to traverse left and right across the work envelope. Additionally, they will have at least one z-axis actuator that travels up and down in and out of the work envelope.
