Robotics and Mechanics – Jacob Nielsen – Project 2


In Robotics and Mechanics project 2 Derek Ing and I are building a race car. The race car will include a steering system, a one light sensor for a booster and stopping. The remote control has a light sensor connected to it with a bar to move between white and black. Black being being fast and white being slower. The car has three motors the front motor for steering and the back two for moving the car. The two back motors are hooked up to a gearing system that makes the car go faster. The front  motor will turn the steering system. The control will have two touch sensors, the touch sensors will control the steering. We will try to make this car as close as possible to the car in the inspiration video.



We had a couple problems while working on this. Our first problem was the steering. We could not figure out how to work the steering, we had to settle on programming steering. Our second problem, was the gearing, the gearing was not working so we had to secure the gearing better to the care. The gearing is designed to make the wheels go as fast as possible. At first we thought that the gearing system was on to much weight or it was just broken. We fixed the gearing system by making the car weigh less and that solved the problem. The programming had some problems at first but Derek and I were able to fix it. The car structure at first as not stable and was coming apart, we built a new design and were able to rectify the stability problem. One of our other problems was the wires the wires were kinda in the way of the wheels on the car we could not solved but we just moved the wires out of the way of the car. We solved all of the problems some of the pictures below are the problems we faced.

Final Product/Conclusion:

Unfortunately,we could not hook up the first steering so we had to program it to steer. The controller is the same as we planned and it works perfectly. The structure of our car is now stable and works perfectly. The final product has two touch sensors, one light sensor and three rotation motors. The touch sensors are for moving the car and steering. The light sensor is on the controller with the touch sensors, its main function works as such, you turn a knob with a black or white brick the black one is the the signal to make the car go fast and the white one is in charge of making the car stop instantly.






This is our Blueprint for our project this blueprint includes the remote control and the car. This blueprint helps our plan for our project. Me and Derek created the blueprint from the inspiration video below.

Inspiration Video:



This Steering did not work because of two reasons the moving lego piece was either to long or to short. We could not find a piece that worked perfectly. The second problem we had with this was that we could not stabilise this to the car so we could not put this on to run the steering. The bottom pictures are the final product of the car and the remote control.

Actually My Final Programming

Final Programming

The Programming had some problems such as the steering was not working at first but Derek and me fixed it by changing the steering on a certain block. The light sensor did not work at first because we set it to the wrong light so then we had to fix it by changing the colour on the light sensor. The touch sensors were not the problem they work perfectly. The motors at first did not work because of the programming because it was the motors were set to different speeds and a different direction. The programming took 6 lessons because it was very advanced and we had to think hard to make this programming work
