A small CNC machine is useful when you want to make something mechanical parts by yourself for your robot or other structures.
Recently, I have got a small one for myself and use it to make a simple 2WD Robot Chassis quickly.
Step 1: Materials
Firstly I have got a PVC board for the main part. Then I need two DC motors and wheels.
I bought all of these materials through the internet. They don't cost much.
Step 2: Make the Frame
Use the CNC machine to make the frame.
Step 3: Install DC Motor Brackets
Install DC motor brackets on the frame.
Step 4: Install DC Motors on the Brackets
Step 5: Install Caster Wheel on the Frame
Install caster wheel on the frame.
Step 6: Add Wheels to DC Motors
Step 7: Done!
Next I will make a driver for this robot and use arduino to drive it.
