5.   To hold the axles in place, you can use straws as axle holders. Cut the straws into smaller sections that match
                the width of your car chassis. Glue the straws onto the foam chassis, and ensure that they are straight on the
                foam board. The straighter they are the straighter your car will drive down the track.

                *TIP* Be sure not to glue the axle to the axle holder (straws). This would prevent the axle from being
                able to turn, therefore acting like a parking brake.

            6.   Attach the pulley and wheels to the end of the axles. Be sure to glue or tape them on so that they rotate with
                the axle as it turns. If not attached to the axle it will spin inside the wheel or pulley and the car will not move.
            7.   Attach the hobby motors to the foam board using hot glue or another adhesive. Apply a small amount of
                glue to the bottom of each motor and press them firmly onto the designated spots. Make sure they are
                aligned properly and parallel to each other to ensure smooth movement.

            8.   Connect the motors to the battery holder using wires and connectors. Strip the ends of the wires and twist
                them together with the corresponding wires from the motors. Use electrical tape or soldering, if necessary,
                to secure the connections. Attach the battery holder to the foam board using hot glue or other adhesive.

            9.   Once all the components are in place, insert the batteries into the holder and test the functionality of
                your prototype. Observe how the motors operate and make any necessary adjustments to ensure proper
                alignment and movement.
            10.   Throughout the prototyping stage, take measurements and record data related to the performance of your
                car. This information will be valuable for evaluating and refining your design later on.

            By prototyping with hobby motors and foam board, you'll be able to test and fine-tune your race car design,
            identify  any  potential  issues,  and  make  necessary  adjustments  before  moving  on  to  the  final  stages  of  the
            project. Remember to take your time and be creative in finding solutions during this phase.

            Step 3: Designing the Car Chassis in Tinkercad


























            Once you have successfully tested and measured your prototype, it's time to take your design to the next level.
            Utilising the power of 3D printing and Tinkercad, you will design a custom car chassis that will give your race car
            a competitive edge. Dive into the world of Computer-Aided Design (CAD) as you refine your design, ensuring
            both aesthetics and functionality. Here are the steps to design the car chassis in Tinkercad:





                                                                           Integrating Robots as a System  115
