Meets for 3 hours of lecture and 3 hours of laboratory each week for 10 weeks.

For laboratory write-ups and data acquisition.

Exercises: Handouts that describe the experiments will be made available on the course web site, along with their solutions. You should work through the lab, referring to the solution. The solution is provided to relieve time pressure and to act as a “consultant” if you get stuck. You can also ask the TA for help if you are confused. Be creative, explore, and have fun in the lab. This is your opportunity to build things that move and see how they work. Pre-Quizzes: There will be a brief quiz at the beginning of each lab testing whether you have read the experiment handout before coming to laboratory. Write-up: Each student will be required to turn in a brief write-up for the lab. The write-up must be typed. You must use a computer graphing program (e.g. Microsoft Excel or Matlab) for all graphs. Zero credit if you don’t do this! Post-Quizzes: There will be a 30-minute quiz in lecture the Tuesday following each laboratory. Final Project: There will be a final project competition involving the design and head-to head testing of a robotic device. The final project tournament will take place on the day of the scheduled final exam, and will replace the final exam. There will be a write-up due on the day of the final paper.
