Sophomore Design
A Proposed Project FormatR. E. Haskell
4/26/2003
Sophomore Design
• Common design project (competition) for all groups
• Model of “automated highway system” in which a vehicle automatically follows a “line” on the road
• Competition at the end of the term in which groups “race” their vehicles by following a “black-tape” course
Automatic Lane Detection
Autonomous Vehicle Lane(AVL)

Have EE faculty give a lecture on how transistors work and howto design an H-bridge to provide proper current to a specific motor.How to solder.
Equation for Vs, Vf, VR, VL
• VR = Vf + (d*Vs) / 2
• VL = Vf - (d*Vs) / 2

Have ME faculty give a lectureon linear and angular velocitiesand how to compute motorspeeds to produce particularrobot speeds and steering.Mechanical design, cutting holes, etc.
CML-9S12DP256 Single board Computer
Have CS/CE faculty givelectures on how to programthe MC9s12DP256 in C.
Have CS/SYS faculty givelectures on how to designcontrol algorithms for therobot
CSE 480 – Fall 2003
• Have groups “design” and test this Sophomore design project
• Each group has a $200 limit for their vehicle
• Design should maximize speed to win race while maintaining safety by not running into car ahead on multiple car test
