Layout Drawings







The layouts are edited such that the components appear as they would on the printed circuit board. The layout will however become a copper layer on the bottom side of the printed circuit board and will thus appear mirrored when looked at. Therefore the text is mirrored in order to read correctly from beneath the PCB.







The PCB base is designed to fit the original motorized base's mounting brackets. The PCB is mounted to the base with threaded aluminum standoffs. The base PCB is the support structure for the stepper motor, scoreboard, transmitter and receiver.






The transmitter PCB was designed to mount over the side of the stepper motor. The transmitter is connected to the base PCB via a header connector; the connector facilitates prototyping by permitting easy disassembly.






The infrared LEDs are mounted in 360 degrees radius. The PCB is soldered to the transmitter PCB and fits dicrectly over the stepper motor shaft. The stepper motor supports both transmitter and IR PCBs.






The receiver is fixed to the stepper motor shaft with a brass sleeve. A Molex connector is used to connect the receiver to the main controller. The reveiver is removable for prototyping purposes.






The scoreboard is fixed to the rear of the robot via standoffs. The scoreboard is connected to the main control board via a header and is easily removed. The scoreboard may be replaced by other modules for different purposes.






The charger is designed to fit to the side of the robot. The charger has a DC jack for power input. The power source may be a battery eliminator or a remote docking station for the robot to automatically recharge.
