Robotics and Automation 10, 20, 30

(a)	Explain the purpose of gears, sprockets and chains and pulleys and belts in robotics and automation applications.
(b)	Examine how gears can be used to change the direction of rotation of a drive shaft.
(c)	Compare the suitability of different types (e.g., flat, round, Vee, and toothed) of belts for various robotics and automation applications.
(d)	Calculate gear ratios using the following formulas: gear ratio = # of driven gear teeth/# driving gear teeth gear ratio = diameter of driven pulley/diameter of the driving pulley
(e)	Calculate torque and speed changes using the following formulas: output torque = input torque x gear ratio output speed = input speed/gear ratio
(f)	Convert angular speed of a drive shaft (e.g., rpm) to linear speed (e.g., cm/s) using the formulas: revolutions per second (rps) = revolutions per minute (rpm) x 60 Angular speed (radians per second) = 2 x pi x rps Linear speed = radius of wheel x angular speed
(g)	Describe some of the challenges associated with using pulleys and belts, gears, or chains in robotic and automation applications.
