Initial Objectives

• Build a wall-hugging mouse
• -Materials
• Sensors Top down infrared
• Motors 1.8 degree stepper motors
• Processor Rabbit Card
• Motor Drivers The provided Circuit
• Chassis Made from sheet metal (Aluminum)
• -Additional Materials needed (for initial design
  only)
• Circuit Boards Perforated Type
• Screws for keeping motors and sensor array in
  place
• Wheels (expected to come soon)
• Wire connectors
• Batteries
• Resistors, Diodes, solder and other rudimentary
  parts

4
The Steps of The Dance

• Build the Chassis.
• Complete Sensor array.
• Create the Motor Driver Circuit.
• Create an effective Tracking algorithm.
• Perfect the Tracking algorithm.

Details
2D Plans for Mouses Chassis
-The Motors are off-center because it is
anticipated the batteries will be lighter than
the Motors. -Final Mouse will have the center of
mass aligned on the axis of the geometric
center. -Less Chassis out-front permits a shorter
sensor array to detect on-coming walls. -Flaps
bend up to hold motor in place

More details Sensors
-Sensors are expected to be on one side only (for
wall hugging mouse). -Sensors will originally be
aligned as shown in the diagram on a rectangular
strip protruding over edge of mouses side. -One
sensor, possibly two will be out in the front to
detect on coming walls. -Other sensors detect
side wall.
-Sensors will not be soldered onto sensor array,
but will be attached via use of connectors. This
way any corrections needed will not require
resoldering. -Sensors will be adjustable so that
their height over the mazes wall can be adjusted.

Power

• 12 V will be needed (of course)
• A formal decision on the type of batteries to be
  employed has not been made
• -Nickel Metal Hydride (possibility)
• For this initial design, battery selection is not
  of incredible importance, as we expect to upgrade
  our wall-hugging mouse in order to make it
  competitive.

Motors Motor Drivers

• As provided by the Kit, 1.8 degree stepper motors
  will be utilized.
• Initially, the tutorial provided Motor driver
  circuit will be used.
• This circuit may be modified in the future
  following the demonstration of a capable hugger.

The Expected Mouse
The diagram does not include a missing frontal
sensor (for the purpose of detecting on Coming
walls) Also, the diagram does not include the
sensor circuitry that will be ON board the mouse
