Build Robot Car Chassis Kit – Arduino

In this post you’re going to learn how to build a robot car chassis kit that is commonly used with the Arduino board. You can either watch the video tutorial or follow the written instructions.

Written step-by-step instructions

1) This is the package that you get with the Smart Robot Car Chassis Kit.

2) Open the package – it comes with one screwdriver, two DC motors, two wheels and one acrylic car chassis. There is also a small plastic bag that comes with a battery holder, a small wheel for the front, some bolts and screws, four wires and other required components to assemble the robot.

3) Although this kit comes with the needed wires, since they are a bit short and not very flexible, we’ve decided to replace them with other wires, because we can easily adjust their length. You’ll need one red wire and one black wire for each motor. You can use a wire cutter to cut the wires to your desired length.

4) After preparing all four wires, you need to solder them to the DC motors. Tin the DC motor pins.

5) Then, grab the wire and solder it to the DC motor pin. Repeat that process to all the other wires.

This is how the motors look like after soldering the wires.

6) Now, you need the screwdriver, bolts and screws, and those metal pieces. Start by attaching the metal pieces to the DC motors.

7) Here’s how they look like after this step:

8) Remove the protective adhesive from the acrylic chassis in both sides.

9) Grab the small wheel and attach it to the front part of the chassis.

10) Finally, it is time to attach the DC motors to the chassis.

11) Lastly,  connect the wheels to the DC motors.

Now, your robot car chassis is ready. Here’s how it looks after assembling:

Additional tips:

  • When it comes to building robots with Arduino, we often use an Arduino Nano board, because it’s lighter and fits well on the breadboard;
  • We use an half breadboard that fits nicer on the robot chassis;
  • We usually don’t use the battery holder. Instead we recommend using a portable charger (power bank), it’s rechargeable, occupies less space and is more practical.
  • We use Velcro to attach the portable charger and the breadboard to the chassis. It’s really practical as you can easily attach and detach the components without any damage.

Wrapping up

We hope you’ve found this post useful. Have you ever built a robot?

Did you buy a robot chassis you did you build your own?

Thanks for reading.
