1. Overview
The Isaac16 EDU Robot Controller and EDU Motherboard combine to function as one unit. The
functionality of this smaller unit is very similar to the Full-Size Robot Controller and operates on the
same basic principles. The basic differences on the EDU Robbot Controller are: 1) smaller size and
reduced weight, 2) fewer inputs and outputs, 3) the RS422 Radio is integrated and internal to the unit,
and 4) the Motherboard is removable.
The removable Isaac16 EDU Motherboard is designed to mate only with the Isaac16 EDU Robot
Controller. The removable Motherboard allows the Isaac16 EDU Robot Controller to be used in
multiple robots, while the wiring and robot specific program remain in each robot on the Motherboard.
This modular design allows classrooms to build multiple robots without the need for a dedicated control
system for each robot.
The Isaac16 EDU Robot Controller (RC) receives information from the Operator Interface, gathers
additional information from sensors on-board the robot, determines how the robot should function, and
instructs the robot to perform the functions. The EDU Robot Controller also sends data back to the
Operator Interface, giving the human operator(s) feedback of critical information.
Also, the Isaac16 EDU Robot Controllers gather on-board sensor data via the ANALOG and DIGITAL
inputs. There are 8 digital inputs and 4 analog inputs on the EDU Robot Controller. Switches of
various types may be connected to the digital inputs. Sensors that provide a 0-5V output, such as
potentiometers and gyros (yaw rate sensors) may be connected to the analog inputs.
