• Blinking LEDs
• Miller engine
• One extra circuit
• Lego gear train
• Solar power
• 20 junk points ( points gotten from using
  salvaged parts)

• Blinking LED eyes (555 timer chip circuit)
• Spinning tail (solar powered miller engine)
• Moving head and neck (Lego gear train)

4

• This circuit controlled our monster dolls eyes
  His eyes were made from two red LEDs, which were
  soldered to the 555 timer chip circuit.

• Our Lego gear train moved Lemons head, back and
  forth.
  
• One obstacle that we faced when building the gear
  train was finding the correct amount and order of
  gears to use. It took a while, but we finally
  figured it out.

6

• Our miller engine is powered by a solar panel,
  and it spins Lemons tail with a motor.
  
• It took a lot of trial and error to mount the
  motor inside of Lemon, but we finally got it.

• In this project, we were required to have at
  least 20 junk points, which were earned by using
  parts that were salvaged from scrap. We

• The three main problems that we had were

• One Absences. Both partners were absent for
  much of the project, and that made it difficult
  to complete the project on time.
  
• Two The Gear Train. The gear train took a long
  time to get right. Due to the amount of weight it
  was moving, it had to have a lot of torque, and
  had to be very stable. This took a lot of effort
  to get correct.
• Three Snow/Rain Days. Due to all the snow and
  flooding, getting the project done at
  school/study table also became difficult, and
  time was a big issue with this project.

• How we solved these problems was

• One We solved the absences problem by staying
  after school and working (on the presentation) at
  home.
  
• Two With time, effort, and no small amount of
  help from Mr. Schelle, we finally got the gear
  train to work just right.
  
• Three This one was harder. Thankfully,
  Mr.Schelle let our entire class have an extension
  on this project, due to the off days. This gave
  us the time we needed.

11

• During our project, we had a brief visit from an
  elementary school, Cascadia, to learn about
  robots.

12

• In the end, this project was really fun. It took
  a lot of time, and there were a few kinks that
  had to be worked out, but in the end, it was
  really cool to build such a complex (for us, at
  least) robot.
