Overview
- Design and build an autonomous robotic mouse to
find its way to the center of a maze as fast as
possible

Sensors
- Top-down Sensors
- Side Sensors
- A/D Converter
- Testing to determine implementation
- Placement
- Coding with Movement
6
Top-Down Sensor
- QRD1114 Reflective Object Sensor
7
Possible Placement
- Two sensors on each side
- One on the front and back
- Testing to determine physical geometry to allow
turning without losing orientation
8
Side Sensor
- Sharp Distance Sensor (GP2Y0A21YK)
9
A/D Converter
- Sensor output analog (voltage), depending on
distance - Rabbit reads in digital
- Sensor --/--gt Rabbit
10
Possible Placement
- Two sensors in front and back of mouse
- Angled to account for the distance limits
- Can determine distance after A/D conversion
11
To Do List
- Test Motor Torque with Prototype structure
- Complete acquisition of parts
- Design PCBs
- Complete final structure
- Develop code
- Test and Debug
12
Expected Problems
- Time! TIME!!!
- Developing/Fabrication of structure
- Programming/Debugging
- USB Charging too slow?
- Motor torque
- Sensors use and implementation
