Students often criticize the course for a lack of experimental hardware.
They also have a desire to work with equipment that is used in the industry. In order to improve system dynamics and controls education at Georgia Tech, a remote access laboratory was created which provides students with practically unlimited remote access to a hydraulic manipulator. The manipulator was given the name HAL, Hydraulically Actuated Lifter, because it is designed to function in a manner similar to a forklift. Access to the manipulator is provided through the Internet connection. The research work that will be presented focuses on the design of the mechanical structure, the hydraulic system, and the electrical interface between the manipulator and its control computer.
