Use your weights and the equations introduced in this activity to calculate the
coefficients of static and kinetic friction for the SumoBot tire treads and the
sumo ring surface.
Put the SumoBot on the scale, and add mass until the scale indicates your
SumoBot and payload is just under 500 g.
Repeat these tests with your 500 g SumoBot.
Compare the forces of friction the sumo ring exerts on the tire tread with and
without payload.
Remove the tire treads and repeat the experiment.
Repeat Activity #1, and test to find out if the position of the payload added to the
SumoBot can be adjusted to give it added advantage.
Be creative with testing different materials for tire treads. Try cutting a balloon
in half and then stretch it around each tire. How about the material in surgical
gloves? Neoprene, broccoli rubber-bands, sections of bicycle innertube, silicone
tubing, paint-on urethane, rubber cement?
