1. Smart Lens Robot
William McCombie
IMDL Spring 2007

2. What it does
Reads RFID tags from the environment to determine its next location
RFID tag will contains commands such as “Face 37º north, go forward 10 units. Camera level, camera height 42 units. Take picture”
Captures pictures or video from certain points
Uses RFID instructions and on-board compass to determine motion

3. How it will be set up
The robot will be a flat triangular platform with two sets of wheels for locomotion
Each wheel will be independently controlled, with a set of free moving casters for stability
A standard tripod will be set on top

4. Parts to be used Atmel ARM CPU with board Re-used from previous class
USB
USART
A/D
PWM
RFID reader and tags
Available in the Packaging Lab on campus
Interface with the board with serial connection
Compass and IR sensors
Ordered online
Servos and motors
Need to be capable of carrying a load
Power supply
Specs to depend on what parts are used

5. Sensors
Camera – Not a sensor – Images will be recorded but not interpreted. Memory card can be removed and plugged into a PC
IR/Bump switches – collision avoidance
RFID device – Can read and write to RFID tags
Compass – Used to determine current direction

6. Actuation
Motors and Servos
Two for motion and rotation
Two for camera adjustment
One for height
One for tilt/pitch

7. RFID Tags Can contain 64 or 96 bits of information
Some bits used for overhead if standards are complied with
Can be programmed and reprogrammed with the right hardware
