track testing
Track Testing

Half of total project time

Several runs on track after each new code implementation

integration testing
Integration Testing

Integrate module into main function

Do track test again

day before competition
Day Before Competition

Practice board in hotel

Sign up for 30 minute slot

Completed course twice

Only three teams completed track


Each team had two runs on the track

After first run

One 20 sec penalty for not attempting to grab one of the cans

Placed 2nd out of 37

2 nd run
2nd Run

Exceeded time limit

Obtained one penalty

Did not attempt to pick up one can (20sec)

Placed 9th out of 37


Claw worked great but was too much for this particular competition

More light sensors

Smaller platform and wheels
