I originally made a instructables about my beetle robot version 1.
It is now time to show you a new version of this wonderful robot. This new version is much easier to build and fool proof!
The beetle robot (Beetle bot), is a very simple and efficient robot that use no electronics component to avoid obstacle in his path. It use two SPDT switch to avoid obstacles by reversing the opposite motor to pivote and free himself. There is no silicon chip, that is, no integrated circuit, no transistor, no resistor, capacitor, etc.
This mean very cheap to build!
The major modification is the cross antenna. When you have cross antenna, obstacles like a chair leg won't be any danger to the robot. The robot will be able to avoid it. On the original design, the antennas where in a V shape and the chair leg would go right in the middle of the V and the robot would had a hard time to get free.
By having the cross antenna, it also help with the assembly of the robot. The switch are closer together which help in the soldering of the wires.
Here is a little resume turn into a video. Check it out!
This article was created because I got contacted by a Make editor. I then took pictures and redid the beetle for an article that I wrote in the MAKE magazine Volume 12.
After a few month I saw this: Top articles in MAKE 1 - 12.
It turns out, that my article was one of the most read of there digital magazine!
Here is the digital version of my article.
I took 134 pictures, that is 235Mb of files! I had a really hard time to choose the perfect pictures to make this instructable!
In 2010 I made a internship at www.solarbotics.com and made this solderless kit
Look at blue and the green beetle bot in the pictures! They look awesome!
The only thing you need is a screwdriver that we give in the kit!
