Table 2. Current sent to individual wires

Table 2. Current sent to individual wires

The current sent to each wire changes during one period. For this reason it is difficult to accurately calculate the power consumption of the prototype using the basic multi-meter available. Since exact power consumption data was not needed, a more complicated data acquisition system was not implemented. To calculate a rough estimate of power consumption, the current in the two supply wires to the power supplies (instead of individual wires) was measured. The current draw on these wires was found to be relatively steady. Table 3 contains the maximum and minimum current in supply wire one (for vertebrae 1 and 4) and two (for vertebrae 2 and 3). The minimum and maximum power consumptions were calculated to be 292.8 W and 333.6 W respectively.
