As your confidence and skill level grow you can design and build your own components. In addition as you work with different materials such as wood plastic and metal you will learn the properties of each and how you can use them in your own robot designs. When I first started to design and build remote-controlled robots I used a very simple motorized wheel assembly taken out of a toy car and made bodies out of poster board and construction paper. Figure 1-11 shows the plans for one such robot. I tried to make these robots life size 3 to 4 feet tall. They were fun to design and build and taught me a lot about what would work without being expensive to construct. If you are a first-time robot builder I suggest that you try one of these paper robots. Whether made of paper or wood and metal all my robot designs have four basic subsystems a motorized base a remote control system a power supply and a body. Motorized Base The motorized base for your robot can be the most difficult subsystem to design and build. You can save yourself a lot of trouble if you design around this part of the robot. Instead of designing the robot first and fitting the motorized base to your design design and build the base first and then fit your robot body to it. The base generally holds all of the internal parts or guts that make your robot work. In Questor for example the base has the wheels mounted on it as well as the batteries which can be quite heavy and the control system. That is why he looks the way he does. The old saying form follows function is true in robot design too. The most important part of the base is the motor-driven wheels. This is where many myself included robot builders have the most problems. Do yourself a favor and buy motorized wheel units. A supplier is listed in the back of the book. These units already have a motor mounted to a drive wheel and usually the assembly is in a frame you .
