Selecting Wheels

By Janavi

Objective: Determine the type of wheel that best suits the chassis

In the Choosing Drive Train E-16 we decided that we will use the chassis BigWheel. We know that our wheels need to be light weight but we need to determine the size of the wheel that will keep our robot far away enough from the ground for us to provide enough clearance to allow us to climb over the crater rim. But, if we choose wheels with a large radius we risk raising the center of mass.

	Pros	Cons
Ironton 12in. Solid Rubber Spoked Poly Wheel	light durable	Large Turns Extremely Large
Ironton 16in. Solid Rubber Spoked Poly Wheel	light durable	Raise center of mass Extremely Large To prevent tipping we now have a much shorter distance to correct imbalance
Ironton 8in. Solid Rubber Spoked Poly Wheel	light durable	Not large enough to significantly move the center of mass
