Implement - Manufacturing


Implement - to construct and manufacture our components individually, the platform and the arm, from the raw materials, Acrylic, and then install them altogether onto the car itself.

Firstly, we drew pencil lines onto the acrylic so that we know the dimensions and where exactly we are suppose to cut it and drill holes on it.


Next, we cut the acrylic into the exact size we wanted using the acrylic cutter machine.

Then, we bent the acrylic, using the heating machine, to create the inverted U-shapped platform and an U-shapped arm. 

We decided to drill 3 holes on top of the platform to secure it onto the car. 1 hole on the right side of the platform and another 4 holes on the left side of the platform to secure the motor to the platform. We also drilled a hole on both sides of the arms so that we can attach the right arm to the platform using a pin and the left arm to the platform using screw.

Lastly, we assembled everything together which includes; the screwing of the platform onto the car itself, installing the motor to the left side of the platform, attaching the left side of the arm to the motor and the right side of the arm to the platform using a pin.

Alas, things did not go as planned(as always). We accidentally broke the acrylic while fabricating, but we did not gave up. We redid everything again and persevered to the end.


We have improved our design as it is easier to fabricate and easier to understand too.
We have cut the right side of the platform, and removed it, and bent the right side of the arm inwards as we felt that the acrylic is very stable and we can operate it even if only one end of the arm is screwed to the motor. Moreover, this also helps to reduce the mass and hence improve the speed. And then the other end is held in the air. We think that is helps to reduce friction. 
 
As such, we took the U-shapped arm we have created and bent the right side inwards using the heating machine. 


Secondly, we decided not to drill any holes on the platform. Because we thinks that no holes are necessary as the motor is very secure.
 
We have also changed the number of holes on the arms. We only drilled 2 holes on the left end, which is straight, to tighten it to the motor and the car itself.

We then assembled everything onto the car; the screwing of the platform onto the car itself, installing the motor to the left side of the platform and attaching the left side of the arm to the motor. 

Finally, our fabrication is finished and our car is produced.
