Lego Mindstorm/ Robotic Experiment

In class we were taught how to put together a motor vehicle out of lego pieces. I was familiar with putting together and operating a robotic motor vehicle from a few classes I had taken in high school a few years ago.

After putting together the robot, we were instructed to perform different tasks with it, such as rotating the wheels in certain directions, at certain speeds.

We learned how to measure the distance a wheel travels by calculating the circumference of a wheel: pi * diameter. The diameter of my wheel was 5.5, therefore the circumference was 17.3. After converting the circumference into meters, my wheel was .173 meters.

My results after the three power levels were this:

Level 50/1 second:

wheel rotated one time, 360 degrees rotation, .173 meter distance, velocity .173 meters, distance with ruler .22, % error: 23.9%

Level 75/1 second:

wheel turned 1.35, 482 degree wheel rotation, .2317 meter distance, velocity .2317, distance with ruler .26, % error: 11.64%

Level 100/1 second:

wheel turned 2.17, 778 degree rotation, .375 meter distance, velocity .375, distance with ruler .39, % error: 4.38%

    It is my belief that mesothelioma will be the most lethal cancer. It’s got unusual features. The more I look at it the more I am certain it does not behave like a true solid tissue cancer. In the event mesothelioma is actually a rogue virus-like infection, therefore there is the chance of developing a vaccine and also offering vaccination for asbestos open people who are at high risk connected with developing long run asbestos related malignancies. Thanks for discussing your ideas about this important ailment.
