Test 1: Mini Power Draw

The mini ran for 4.33 hours using an inverter on a 12 volt 18 aH battery. Divide the aH by the time so 18/4.33 and then multiply by the 12 volts to get an approximate 50 Watts of power. I had iTunes playing music and SETI running the entire time to tax the CPU and then 2 usb cameras plugged in. Overall, I think this is the upper bound because the battery I was using is quite old (4 years). I am going to pick up another battery and run the test again. Also coming soon will be CAD drawings of the robot layout using Sold Works. In the future, I'll try to convert this to an open source cad program, but for now I am trying to brush up on my SW skills.
