Just to recap from the last post, here is a listing of the required materials with our parts list pretty well established, let’s start adding specifics. More Information
Base
Housing
Two wheels
Two continuous rotation servo motors5.Ultrasonic proximity board
Arduino controller board
9-volt battery w/ cable
Tour AA batteries w/holder
DPST switch, two LEDs, two 1Kohm ¼ watt resistors
Double sided foam tape, hot glue, paint, and misc.
With our parts list pretty well established, let’s start adding specifics.
First, with a little innovation, a plastic container such as a cottage cheese or yogurt container can be used as a housing for the robot. A circular piece of plastic, plywood, aluminum or cardboard can be cut to act as the Base which will hold the rest of our Robot. Slots need to be cut to accommodate the wheels.
The wheels to be used on our Robot will be driven by modified hobby servos so they must fit directly on the axles. There are a multitude of the appropriate wheels available. They can be purchased individually or along with the servo through Amazon. I have some suggestions on the reviews page.
Mobility and maneuverability can be accomplished by traditional methods using DC motor drive and wheel rotational steering. But, the precision control provided by modern servo motors or stepper motors allow applications requiring robotics digital control much more attractive. The most common mobility mode when considering other possibilities including caterpillar drive, legs, flying, swimming and rolling is the wheel.
The main advantage of using Wheels is that they provide reasonable speed, accuracy, and stability for a robotic base. From Home Robotics Hobbyist to Robotics Engineers they find the simplicity of using wheels one of the best solutions to mobility. Researchers and Wheel manufacture designs many types of wheels including standard, orientable, ball, and omnidirectional wheels. Perhaps the most interesting design is the Mecanum Wheels.
