| | | Hi All, I built a little robot that has two wheels that are tilted such that instead of being parallel to the ground the axles stick up at an angle approximately 75 degrees to the ground. Tilting the wheels this way raises the effective axis of (...) (22 years ago, 24-Jul-02, to lugnet.robotics)

| | | | | (...) Wheelchairs, particularly those used for sports like racing and basketball, also use negative camber. They can get pretty extreme too. When I worked for a wheelchair manufacturer, we'd do camber of up to 18 degrees on each wheel. Adrian -- (...) (22 years ago, 24-Jul-02, to lugnet.robotics)

| | | | (...) I don't know if camber is the correct term to use here. If so, my robot wheels have 75 degrees of camber, and the wheels are cambered in instead of out (the wheelbase is really narrow). It's really a different kind of wheel design. I'm not (...) (22 years ago, 24-Jul-02, to lugnet.robotics)

I work for a company that makes equipment for testing vehicle suspension kinematics, compliance, performance and durability. I spent the last (...) (22 years ago, 25-Jul-02, to lugnet.robotics)

| | | | Dean, After looking at the Androbot, I *finally* figured out what is going on here. At first glance, it looks like the robot has some extra camber - well, a LOT of camber. But what is it doing, exactly? In a normal robot the wheels that go straight (...) (22 years ago, 25-Jul-02, to lugnet.robotics)

It uses the big 81mm balloon tires at about -75 degrees of camber and will recover from being tipped forward or (...) (22 years ago, 25-Jul-02, to lugnet.robotics)
