We continued our experiments using the Lego Mindstorm and NXT robotics set, and this time we used a flashlight with magnets inside it to produce energy through shaking, and then measure the output of energy through the robot.
The flashlight has several magnets inside of it, and when shaken the motion produces energy that is then sent to a sensor that measure the output. We did this several times for 30 seconds each at different paces, fast, slow, and just for fun three shakes in a row followed by a pause.
In the first round, Jason counted 85 shakes which came out to 153.4535 volts. Sarah’s trial had a count of 32 slow shakes which was came out to 53.09822 volts. Lastly, my trial had 29 staggered shakes (three shakes, then a moment of rest continued for 30 seconds) which came out to 36.59198 volts.
We put this data into a graph in Excel and included a linear trendline. The data shows The more shakes,the more energy it produces, so for more energy the flashlight must be shaken longer and more frequently.
