This is my first line tracer robot.I made it about 1 or 2 years ago.
Step 1: How Does It Work?
Step 2: Materials
- CD/DVD disc
- Power Switch
- Motor Driver L293D
- Battery Hold
- Bolt and nut
Step 3: Electronics
Step 4: Sensors
Step 5: Body
On the obverse of the CD there are the motor driver and some of the wires ,battery hold and the power switch. I drilled holes in the CD for the wires ,the power switch and the bolt.
In fact first I put the battery hold on the underside but after that I put 3 batteries and because there was no place for them I put them above everything.But I haven't photo of the final version.
The bolt with the LED on it is for 3rd leg or something like that.
Also the nut is glued to the body and the bolt gets into it.
Motors are on 90 degrees from each other.
Step 6: The Line
This is my line.
