Unformatted text preview: 10 seconds? If not, what are possible explanations for the error? o No the time delay was not around 10 seconds. The errors include anywhere from measuring error to human error. -Did your measurements fall in the ranges in Table R2? o No overall the measurements fell into the ranges of R2.-Explain any error between theoretical and actual resistance in the 15 second delay in Table R1. o The main error is that the results are based off of previous results which could have not been exact which would change the time delay.-Was there any difference in time delays for “go and spin” compared to “spin and go”? If so, what are possible explanations? o There were some differences, for instance the time delay difference is from errors of measuring and errors in the robot itself....
