This means that the heavier components like the battery and the electronics should be as close as possible to the motors. So the center of mass should be right between the motors. Height, Length, Width and Center of Mass: To make the most out of the force that the motors are making, we should make sure that all parts of the robots are as close to the source of the force as possible. I found that the motors I chose, which are linked above, did the job flawlessly. For this robot, we want the most speed we can get while still having enough torque to take advantage of it, since if we have too little torque the robot will struggle to move its weight in spite of having high speed rated motors. Torque vs Speed: When choosing our motors we will see that often times the same model has different torque and speed options you can choose from.

This means we have to choose the smallest battery possible without it being so small that it runs out too fast, the lightest wheels possible without loosing the much needed traction, and also light materials in general like making a thin plastic base instead of using heavier materials. So as a first key concept we need to keep the weight of the robot into consideration since less weight = more speed. Weight: If Force = Mass*Acceleration, it is pretty clear that with the same motors, meaning the same force, we need to decrease mass to get the most acceleration, which translates to the highest speed.

Base: 3D printed design - Alternative: plastic, wood, cardboardīefore designing the robot and choosing its parts, it is very important to analize certain aspects of the robot to ensure we will get the most speed out of it.

LiPo battery: 7.4v (2 cells) 450mAh, almost any brand is fine.

Wheels: Pololu wide wheels - Alternative: Pololu thin wheels.

Motor brackets: 3D printed motor brackets - Alternative: Pololu motor brackets.

Something to make the base, I used 3d printing but it can easily be made with wood, plastic, cardboard or whichever material you have and think would work.

8 push-up resistors (can be anything from 10k ohm to 100k ohm).

LiPo battery of required voltage - Can be exchanged for regular batteries.

Some screws to hold things together - 1/8 inch or less if you want them to be able to hold the Arduino.

PCB etching tools and materials - Can be replaced with a breadboard but will take up more space.

The competitions I go to have a 2cm line width of white over black and also have small horizontal lines at the start and end of every straight section for the robot to detect and change speeds taking advantage of the straight path. The race track can be either a black line on a white background or the other way around. My robot, called Yeti, is almost 12cm wide and 20cm long, which are the competitions limits in my country, and the cost was aproximately 75 US dollars, but the price might be different for you depending on what components you choose.

Nonethless, every or almost every aspect of this robot can be modified to adjust for the needs, skills or budget of the maker. The original objective of this robot was to take it to competitions where it would race against other robots, so my design always focused in achieving the highest speed while conforming to the rules of the competitions. This type of robot is very popular and can be used to teach some very powerful physics, electronics and programing skills and concepts while still being very fun and simple to make.
