Building & Development Of The Chassis

I thought it would be an easy task to build the chassis, however it was not as easy as seemed. This was due to the fact that the screws and bolts were very small and fidly. The progression when making the chassis was all recorded by taking pictures of the chassis at different stages. These can be seen below.


























I first started off by building the main body of the chassis which can be seen from the picture above. It seemed to be the strongest way of building the base.

































The progression of the chassis can be seen from above as i added a diagonal strip and attached it to the main body to give the circuitry some protection from falling out and this also made the body of the chassis stronger. The strip you can see at the front is for the rotation of the front wheel .

The two pictures above, show the completed body of the chassis without any of the circuitry and wheels. For extra presentability, a chair was added to the chassis above the block situated at the back of the chassis. The design proved to be strong when holding the circuitry and batteries. This can be seen in the picture below.

The picture above is the chassis holding the circuitry . A better effort could have been made for tidying up the wires on the chassis , however, greater this was not done as we had issues with making the chassis turn when following the line.

A clearer view of the wheels and the LDR's is presented in the picture above. We had to put a cover over the LDR's for their proper functioning and the chassis was following the line. However, unfortunately, one day before the date of testing, our right motor stopped working for some reason, which in my view was unfortunate as the buggy was functioning one day before the test. Also, the backwards slop of the buggy allowed the batter to sit under the circuitry and not move out of place. This can be seen in the picture above.
