The Wheeled Walker

An Extreme Creation:

Project: Making a robot with wheels on the feet

Members: William, Steve, Tats

The basic design for this robot is simply a modified hexapod with wheels attached to four of the six legs. The Wheeled Walker is designed to be able to move quickly over smooth terrain using its four wheels. It avoids walls and large objects using two sonar sensors that are mounted on the top front of the robot. When the robot comes across an object that is small enough for it to climb over, it stops and climbs over. There is a sonar sensor mounted on the bottom of the robot to detect smaller objects that the robot is capable of climbing over. To reduce the amount of interference from the three sonar sensors aimed in generally the same direction, there is a divider that separates them. Hopefully we can get better, more consistent readings from this design. The final modification we made to the hexapod was to lengthen the legs so that there was more clearance between the servo motors mounted on the bottom, and the ground or anything that passes under the robot during movement of the robot.
