2. Mechanical System Diagrams Solution allows for some ‘play’ with the universal joint – won’t bind as easily.

3. Mechanical Linkage Constructed From:  Pulley or Gear  2 machined spacers  Connector to Solar Panels (pre- fabricated)  Bolts …but will it hold up to our motor forces?

4. Stress Tests: Affect of a Motor on Assembly Parts Safety Factor: >200 for each piece Deformities: Shown on a 5000:1 scale

6. Summary Problem: The temperature of the solar panels must not exceed a maximum temperature. Constraints:  Must work on any number of panels.  Must have both an automatic and manual control.  Must have a maximum cost of $200 per panel. Solution: Solar panels will be automatically covered when they reach a set temperature. Solution Constraints:  Controller and motor for each panel.  Open, close and power off override controls.  Demonstration system estimated cost of $185.
