Assemble Elegoo Smart Car Robot Kit

Recently I received a Smart Car Robot Kit donated by Elegoo for the Visuino development. I already had another kit that I have used in few Tutorials, but I must admit, the Elegoo kit really impressed me, and immediately became my primary platform for robotic experiments with Visuino!

The kit is by far the most affordable robot kit that I have seen for the features that it includes, and I would wholeheartedly recommend it to you. As you can see from the pictures that I have taken during the assembly, the quality is also very good.

Before I post some Visuino Tutorials with it, I decided to post Assembly Instructions, and made this tutorial.

Step 1: Opening the box

Opening the box

The Smart Robot Car kit comes in a nice plastic box with top layer organizer (Pictures 1, and 2), and includes DVD with assembly instructions, tutorials, and demo projects.

Step 2: Preparing the motors to be installed

  2. Take out the Motors, the Aluminium Blocks, the bolts and the nuts from the plastic bags (Picture 2)
  3. For each motor insert the long screws through the holes from the side with the small sticking out yellow pin to the flat side (Picture 3)
  4. Place the Aluminium Block so the screws will go through the holes on its big flat side (Picture 4)
  5. Screw the nuts on the bolts (Picture 4) and tighten them with the hexagon tool (Picture 5)
  6. Do the same for the 4 motors (Picture 6)

Step 3: Installing the motors on the Chassis
