Battery power calculations 

To power our CVC we used a 6-pack of AA batteries (~9V nominal) that have a rating of 2500 mA-h. A detailed analysis of our current draw is seen in the table below. We had to measure the quiescent current draw of the servos, and for the others we used the worst case scenario for all the components (accelerometer at +/- 1g, force sensitive resistor at lowest resistance), and we assumed that the components were on 100% of the time which is definitely not true. Even with these safety factors we get only 166.9 mA of total current draw, which equates to 15 hours of battery life!
