James Bruton’s newest robot climbs stairs | Arduino Blog
After finishing his recent Binbot 9000, James Bruton noticed a serious problem: the robot can’t climb stairs. That is an issue when his home does, in fact, contain stairs. Bruton has plans to build a beverage delivery robot and didn’t want to make the same mistake again. So to test the concept, he developed this prototype stair-climbing robot.
This robot climbs stairs using an interesting series of mechanisms. It has three wheeled sections, and the first and third sections can lift up relative to the middle section. The front two sections have differential drive motors, while the rear section only has freewheeling omniwheels. A sliding lead weight on top helps the robot shift its center of gravity, so it can balance on whichever wheels it needs to at any given time. Finally, the rear section slides forward and backward on rails, so the robot can move forward as it moves up each step.
