Results/Lessons Learned

• Always design for tolerance!!!! 

• Find creative solutions to redesign/re-engineer a component (given that it is cost-effective, non-time-extensive, and doesn't breach the component's functions/objectives/constraints. For example, when the gears I printed didn't have enough tolerance to fit the motor shaft, I heated the gear with a lighter and while it is semi-soft, I pushed the gear into the shaft to make it conform to the right geometry. This saved me printing time and cost.

• Always check for multiple supplier channels - got components for too high of a price in a robotics store VS. cheaper on Amazon

• YouTube and online tutorials are super helpful when you don't know how to use a part. For example, I did not know how to wire up the ESC to the receiver/transmitter circuit at all. Luckily, I found useful tutorials that taught me what the different channels do and what polarity each of the wires corresponded to. 

• I got to practice my soldering skills a lot more too, since I had to solder all the wires in my receiver circuit.

• When gluing things together, bear in mind which components move TOGETHER and which ones move INDEPENDENTLY! For instance, when I was gluing the axle+wheels sub-assembly to the car, I overlooked the fact that the axle needs to rotate about an axis independently, in order to drive rotary motion from the wheels.
