ROBOTICS
کاربر فعال مهندسی رباتیک
آموزش ساخت ربات سپور به زبان انگلیسی
Introduction
As our final project, we decided to design and build a robot capable of vacuuming the floor of a room or area without any human interaction other than just starting the unit. We realized the need for a cheap and convenient product that can be easily used to vacuum a room on its own, saving a person valuable time.
The robotic vacuum is mainly built from a circular piece of foam board, as shown in Figure 1. The robotic vacuum uses a rotating brush underneath the unit to vacuum a carpet as it passes over it, as shown in Figure 2. 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. If the robotic vacuum hits an object head-on, it backs up and changes direction. If an obstacle is hit at an off-angle, the robotic vacuum turns away from the direction of the impact. The robotic vacuum’s movement is based upon a random walk around a room, which theoretically will cover the entire area of a room given enough time. The robot is programmed to drive straight until an obstacle is hit. At that point, it will turn and continue driving straight until another obstacle is hit, and so on.
