Description:Description:
The Lab Rat is a micro-controller motorized maze The Lab Rat is a micro-controller motorized maze navigating machine. The rat will be able to navigating machine. The rat will be able to traverse a maze either using an built-in algorithm traverse a maze either using an built-in algorithm or following IR checkpoints within the maze. The or following IR checkpoints within the maze. The Lab Rat will also follow a user.Lab Rat will also follow a user.
► Lab rat will traverse mazes using the following methodsLab rat will traverse mazes using the following methods ““Left hand” algorithmLeft hand” algorithm Infrared Tracking of checkpoints within mazeInfrared Tracking of checkpoints within maze
► Lab rat will store its path within onboard memoryLab rat will store its path within onboard memory► Lab rat will follow a user wearing IR TransmitterLab rat will follow a user wearing IR Transmitter

Risk/Contingency PlansRisk/Contingency Plans► Fall behind on schedule
Descope non-critical project functions Keep all designs at simplest level and add difficulty only upon
completion► Much of the technology is unfamiliar
If we fall behind on one, keep pushing the rest ahead If we’re unable to figure it out one way, try other methods
► Issues with RF link Permanent tether
► Issues with recording the path Send data over RF link to store on laptop
► Unable to achieve battery power source Use tethered power source
► Fail PDR Staple a nice bribe to the user’s manual
