Deadelus
Construction on Deadelus began in the Spring of 2001 and completed in the Fall of 2001 for CSC 419, Software Design Project. The Spring of 2002 Deadelus was retrofitted with a new DC/DC converter and camera.
| Deadelus' new
DC to DC converter is being tested.
The entire electronic stack can now be reliably powered for several hours using two 7.2 volt 3000 milliAmp-hour NiMH battery packs designed for radio controlled cars.

A USB camera is mounted on a two axis gimbal at the front of Deadelus. This semester the camera will be used to locate golf balls. |
| Students etched a circuit
board to eliminate all the wires needed to connect the Sharp GP12D2 IR
distance sensor to the analog I/O board. 3-pin 0.1 inch headers is used
to connect to the sensors while a ribbon cable connects to the I/O
board.

Here is the board ready
to be mounted and connected to the robot. |
| The digital I/O goes to this board designed by Colin O'Brien and is used to control servo motors and lights. |  |
104 Car
| The car's motors, both propulsion and servos, are powered by a 7.2 volt 3000 milliAmp-hour NiMH battery pack. Using pulse width modulated the speed of the car is controlled with the Novack speed controller (orange package). The spped controller also produces a regulated 5 VDC that is used to power the servo motors. |  |
 |
The Pontech SV203 Servo Motor Controller controls up to 8 RC servo motors using a PIC microcontroller. A 5 channel, 8 bit A/D input is also avalable. The interface to the board is via RS 232 serial port. |

Servicing of the robot is
facilitated by mounting the PC104 stack on two rails. The rails mate
with two slots on the deck of the car.
You can see the bottom rail in this picture. |
Handy Board Controlled Robots
|
Lego robots controlled by Handy Boards that use touch sensors to detect walls and then move away from them.
|
 |
| Two touch sensors are on the arm next to the wall. Depending on whether one or two are touching, the robot will back up to avoid the wall and then proceeded again down the hallway. |  |
| Handy Car The Handy Car design is centered around the Handy Board, developed by Fred Martin at MIT. The design is simplified by use of a remote controlled (R/C) car base, and many off-the-shelf parts obtainable at local hardware stores.
