Let's Make Robots!

Here's my "ghetto-duino" complete with LCD!

 EDIT: Had to put this picture at the top.. everyone needs their LMR dedication! :D

Stupid LCD... it's 1 pixel short of looking perfect! cuts off part of the first w :/  

PICTURES BELOW (near the bottom of the post) of the solder job under the board.



Well I finally got my camera taking pictures I felt were satisfactory, so you may be getting an excessive amount of pictures of random stuff. :D

IR and Sensor rangefinding data visualisation

These images were created by stepping a pair of servo motors to create a file containing sensor readings for each possible servo position.

I took 3 readings for each position from each servo and stored them in a file, then read the data back in a seperate pygame program running on a desktop to generate the image. RGB values were generated from the 3 readings from each sensor.


Fritsl, seriously, ever since I borded this place, I've been pondering on that picture of yourself.

What the hell are you doing?

Yawning while scratching your early day's beard?

Watching a naked womens parade strolling outside?

Looking out the window in awe because you just saw something surreal pass by?



messing with the motor outs (A and B)

Just a thought:

(lets call the four motor outputs A1, A2, B1 and B2)

What would happened if I connected a GM10 (with the original spring still attached) between B2 and A2? Like in the illustration below


I was hoping to achieve the following:

Anyone used a camera via microcontroller?

Hey All,

Calculon wonders if anyone has used a digital camera and been able to send the image as data? (serial or i2c)? Basically, Calculon wants a bot to send pictures to his PC/Webserver without having to get involved. Is this sort of thing possible with Arduino? Or perhaps XMOS?



I am a beginner

I would not know much about the robot, who has a detailed description about robots? Thanks!(about  Hardware)

Atmega + camera.

I have thought about atmega + camera idea too, but for use on atmega not sending. I looked at CMUcam but it wasn't so low-cost as it was advertised (100$ it too much). I found http://www.robotshop.us/sfe-cmos-camera-640-480.html . It seems cheap, microcontroller friendly and so on. Only problems are - SMD connections, killer programming and impossible debuging.


So, all thoughts and good links are welcome.

Make robots talk.. to each other.. dirt cheap!

I have this thing in the back of my mind that "the next step" for me must be my robots talking to each other.

IR and Ultrasonic

is it possible to connect GP2Y0A21YK0F ir sensor as a obstacle avoiding and SRF005 as motion detection? btw im using picaxe28x
