AUTOMATIC ROOM CLEANING ROBOT
The robotic vacuum is mainly built from a circular piece of foam board. The robotic vacuum uses a rotating brush underneath the unit to vacuum a carpet as it passes over it. Two stepper motors, aligned across the center axis of the robot, are used to accurately drive the robotic vacuum around a room. Because the body of the robot is circular and the steppers are placed along the center axis, the robot can spin in place in any direction. One free-spinning chair wheel is located at the rear of the robot to keep it balanced. The robot is programmed to sense the direction of a collision with an obstacle using an onboard accelerometer.
