The Mentor is the ideal entry point into the world of robotics and Computer Integrated Manufacturing. The Mentor has an articulated arm with joints similar to that of the human arm and this configuration is widely used industrially. Each of the axes is driven by a DC servo motor with its position monitored by a potentiometer. An in-built controller provides closed-loop control of the system and constantly provides monitoring data for the computer. Programming may be from the computer by setting the data for each axis or by incrementing the axes by selecting them and using the + and – keys or the scroll bar.
