The Crawler

Let's Make Robots Robots

“The Crawler” is my first indoor robot with a range sensor.<o:p></o:p>

In hindsight I can see that I probably should have gone with motors and wheels, but I wanted to make it move with servos and not hack them for continuous rotation. The original plan was to use two extra servos for the elbows, but then the idea of using only a hinge and some form of spring came to me.

The base is an 8mm aluminum plate to give it some weight and stability. The Arduino is mounted on spacers on the base plate. An Arduino protoshield holds the voltage regulator for the servo power supply and headers for the servos and Sharp GP2D12 sensor.

I think this rates are the creepiest robot I’ve seen to date on this site…but damn is it cool!!!

Very cool first robot. I
Very cool first robot. I wonder if you could make a 4 legged robot with those sort of legs. Hope it isnt scratching the floor :P.

Wow! Nice idea and solid
Wow! Nice idea and solid desighn! COOL!!! :smiley:

On your way
Very nice and solid design. Hope it dosen’i scratch the floor. Next step, add more legs. lol

Cool idea

Cool idea, especially the fold mechanism of the arms.

Good example of the KISS principle :slight_smile:

Creepbot

Didn’t I see this little guy in ‘Half Life’?

I too would like to see this 'bot on a “skateboard”.

Love it!

Cool Robot

I’m new here and I’m not very good at programming a robot, so could you send the code, please? And do you really need that shield?

18

I’m sorry. I don’t have

I’m sorry. I don’t have the sketch anymore and the robot was dismantled a couple of days after I shot the video.

When it comes to the shield it just makes it easy to hook up the servos and the voltage regulator. You could probably do it in any number of ways.

Wow thats really cool. That

Wow thats really cool. That was a clever idea for the elastic hinge. With some life like aesthetics you could really make this robot look alive!
