Reverse Engineering

Evidence of Work

Reverse Engineering is a bit different than taking it apart. In this section we have to grab one of our inventions and either improve on it or describe how to remake it. Since this RC car is not really worth remaking, we decided to improve on it.

The main issues were the drive line connections, right steer drift, front locking steering, and inverted steering. Right away we could deduce that the cervo that controlled all the steering mechanics was broken in some way. All work is attached in the report ---->

The first thing we inspected was the cervo. We could tell that it hit something and was a little bent. The steering was inverted and that was because one of the cervo switches was inverted. I don’t know why this is a setting, maybe for British people. The car was also pulling/drifting to the right when driving forward but had no problem reversing straight. We tightened the bolts on both wheels in order for it to drive straight, but that didn’t work. The cervo had some sort of internal issue so we used the remote to overcorrect the right steer by constantly having the cervo positioned left at 0.6. For speed we just used a different battery. We used a Venom LiPo battery 5000mA 50C 11.1V 3 Cell. We had to use 3 adapters, but now it tops out at 40 mph.

reflection

One thing we did well on is problem solving and critical thinking. We we faced a challenge we overcame it very quickly and effeciently. Another thing we did well is deviding the work for the report. We had amazing coloraboration and everyone got to contribute in their own way. One thing we didn't do so well on is finding research for the RC car. Since it was from 1993, we couldn't discover a lot of specific information on the specific model. Lastly, one thing I didn't do well was give my group a chance. I felt like it would just be easier if I did it when they couldn't figure it out.
