Summary

NEW VERSION http://www.thingiverse.com/thing:254244

This is Beta.

Beta is a robot controled by Arduino and a L298N. The communication is via Bluetooth as you can see in the video: http://www.youtube.com/watch?v=WrFWBjptyvQ&feature=g-upl

It has 8 servos: 4 to move the legs, and the other 4 to move the wheels; and 4 motors. To power the robot I have used 4 LiPos I had in my house, they are connected in series so I had to use 3 7805 to regulate voltage.

The servos I used for wheels are microservos, NO CONTINOUS ROTATION, imposible to control...

And for the legs, I used a few I already had. This ones I recommend to be more powerful than others.

The motors are geared and are this: http://dx.com/p/high-torque-80rpm-12v-dc-geared-motor-91628?item=6

The Bluetooth module: http://dx.com/p/bluetooth-board-module-4-pin-121326?item=2

And the L298N to control the dc motors: http://dx.com/p/l298n-stepper-motor-driver-controller-board-for-arduino-120542?item=4

The code for Arduino is the file "Codigo.ino"

I'm sorry for the lack of documentation I promise it will be more complete in the next version, Gamma Project.

Instructions

You need 4 wheels, 4 bobys, 4 legs and 2 bases. You can paste them with so much love and a few of cyanoacrylate (super glue).

I repeat: "I'm sorry for the lack of documentation I promise it will be more complete in the next version, Gamma Project."

The code's anotations are in spanish but I think it is understable. It is in progress too.

The plan is glue it to the mars one's rocket with duct tape. But it is a secret!! So shh... ;)

Like it!

It has a different layout than most 4 legged robots I've seen. Is the layout original? If not, where does it come from?Would you please add a photo of the bottom of the robot that shows the connection(s) of leg(s) to the body.Why are the batteries(?) attached to the legs?How are the motors attached to the wheels to make them rotate? I think I see them inside the "Boby" part in the video,Viewed the video and am impressed with the action.-- Don

Hi Don,

the layout is orginal, but it will change in the next version, I have upload a photo of the connetion servo-leg but i don't like it and this will change in the next version too :)

The batteries are there because of the space. I thought would be a good idea to use legs not just for connect the robot with the wheels. They are also so "big" so in this moment the legs are a good place for the batteries.

The motors are glued to Boby so they cant move. The only part can is the rotor, that is glued to de wheels. I've upload an other photo, 

Thanks for commenting:)
