Basics: Project 040a

 Project name:  How to build the 4WD smart robot car Part 1

Tags: Arduino, 4WD smart robot car

Attachments: none

In this project, you need these parts :

1. 4WD smart robot car set 1pc

2. Soldering Iron (optional) if you need to solder wires to each motor terminal

General

We will learn how to assemble 4WD smart robot car chassis.

 

  • 2pcs acrylic boards (robot chassis)
  • 4pcs wheels
  • 4pcs DC gear reduction motor
  • 4pcs the DC gear reduction motor metal brackets
  • copper collars, bolts, nuts

Step by Step instruction

  1. Robot chassis has a stick-on paper covering. Remove it if you want the clear plastic to be shown.
  2. Attach the four metal brackets (they’re rectangular, drilled blocks of metal) to lowest part of robot chassis using two medium size bolts.
  3. Prepare DC gear reduction motors (
    Strip out the insulation from the wires at each end
    Solder the wires to the motor terminal.
    You can check the motor polarity by connecting it to the battery pack.If it rotates in forward direction ( red wire with positive and black wire with negative terminal of the battery) then the connection is ok.
    If you have motor without wires attached then you need to solder them to the motor. Strip out the insulation from the wires (black and red) at each end, solder the wires to the motor terminals. You can check the motor polarity by connecting it to the battery pack.If it rotates in forward direction (red wire with positive and black wire with negative terminal of the battery) then the connection is ok). Attach each DC gear reduction motor to the metal bracket (they’re rectangular, drilled blocks of metal) using two long bolts and two nuts. Each DC gear reduction motor has 2 wires attached (black and red). Make sure that the wires go towards the center of the robot chassis.
  4. Each wheel has holes with two flat sections. Make sure you line this up with the motor shafts later when you attach them.
  5. Completed the lowest part of robot chassis. Let's start to assemble the top part. You will need four copper pillars and eight medium size bolts.
  6. 4WD smart robot car base assembled. The other copper collars, bolts and nuts we will use to attach modules, extention boards, sensors). See How to build the 4WD smart robot car Part 2.
