The new "Shark" model of our robot

Last year we spend considerable amount of time building the new version of our robotics vehicle. Here is the result - the small tracked vehicle which might be intereresting for researchers in robotcs, AI, computer vision as well as for DIY enthusiasts. All the model, assembling instructions and software are open source.


beginer in electronics needs to program

hi, im a twelve year old boy who is not an expert  AT ALL, but knows the basics

i've made bristlebots, speaker tones, dc motor cars  and other stuff


when i have to program  in arduino UNO i just copy other codes from other people

cause...  I dont know how to program at all!!!! i think arduino's language is c,and i don't know  how to program


anybody knows how to program arduino

and can give me a little tutorial about key words and etcetera like setup, delay, control of dc motors sensor etc...

Adventures In Robots: Robot #2 Bert the Bling Bot

Now that robot #1 is almost complete, (Ajax Harbinger of the Robot Apocalypse, robot entry coming soon), I have begun to plan out robot #2.

Robot #2 will be named "Bert the Bling Bot".  The goal of course is for Bert to be bigger and better than robot #1.  To that end Bert has the following requirements/goals.

How to contol servo speed from serial

Hello all

I have  renbotics ServoShield and I have made a code on arduino where from serialport I can send commads to servos and it happens with that way... S01P1200,S14P2300etc..I mean that  Servo 1 to 1200 posion and servo 14 to 2300 posion

The Social drink Machine

Well, the Romanians at Robofun have built a drink mixing robot. It's not looking like the famous Bar2D2, it's looking more like a 2 axis CNC machine, but it has it's share of coolness. To order a drink, you scan the bar code with your smart phone, get to the site and choose a drink. Then wait for a bar code to be displayed on your phone, place a glass in the machine and show the bar code to the machine's webcam.

Wavefront Algorithm Mapping

Hi, LMRians. I've been reading up on this Wavefront Algorithm Navigation and I understand bits and pieces of it, but not everything. I'm trying to learn up on it so I can use it in my next robot : Project 4L-FRED (Alfred), a butler robot. The robot is suppose to navigate around the house from the dining area to the living room and serve drinks to guests. The robot will have pre-recorded messages like greetings and stuff like asking what drinks the guest would prefer.

Artist, first time robot creator

Hi everyone. I'm an art student who's doing my instillation for my Advanced Drawing class on automated art and the creative power of robots. Needless to say I'm quite lost when it comes to the mechanics of it. I got ideas, but ideas don't mean shit if they're not backed up by knowledge. That's why I'm asking you guys for help, and hopefully I can take the advice and use it to make some really effective pieces.


Axe - the sumobot

Hello hello!

As you can guess, I am making a new robot, and it is a small sumo!
- Picaxe 14M
- 2 modified micro servos
- 1 LDR to see the line of the ring
- Sharp IR sensor
- Bottle cap wheels until I make up a better solution (Yes, lol :D)

And when I will receive parts, or get something done, I am going to update this until it is time to post a robot!
Tomorrow (I think) I'm going to post schematics and maybe printed layout ready to make it pcb!
