Chapter 2 Gears
Gears have many roles and purposes. Gears is what makes your robot go faster, makes your robot have a lot of power and can also make your robot go slow depending on the gears. There are two words you need to know one is the driven gear which is the gear attached to the wheel, driving gear is the gear attached to the motors. Finding the gear ratio you must first divide the number of teeth on the driven gear by the number of teeth on the driving gear. If it turns out that the gear ratio is below 1 that means your robot will move fast with less power. If somehow you want to increase the speed and power you can create the gear train which multiplies the ratio for gear 1 and the ratio for the second gear. Bevel gears are helpful in changing the direction of the force this is excellent if you don't have room for the wheel. Pulleys can be used to lift an object and have the same characteristic as gears.

Thank you for your post Brandon. I noticed that your writing seams be reflective of some of our short class discussions and picks out some minor points listed in other students' blogs. I feel that it is missing some of the key points from the reading however. I'd love to see your reflection in your blog focus more on what YOU learned from the reading.
