Beam photovore problem

Ok so I made this beam photovore robot using an online tutorial (google: rays beam robots) and after I completed it only one motor moves. Watch my video below.

arduino and SLAM


I am developing a robot platform for children for educational purposes. My aim is to build a sub 100$ bot with arduino brains. I myself is a good programmer, and if I were to do it for myself, I would use an ARM or a better platform, but I have to constraint this project with arduino.

I have already designed some parts, and I have access to a 3d printer, so it is going all well. I already have a servo/sharp IR sensor scanner, and currently I am using a tamiya tracked vehicle for platform.

Experimental RC Robotic Hand

Introducing my Experimental RC Robotic Hand. I'm going to use it for a robot that I will use to take on Ro-bot-X's "Search And Rescue" Challenge. It's purpose is to get a hold on the drink, obviously. This is only Version 0.2, I'm am currently building a lighter and easier to use grabber to replace the heavier hand that is attached to the winch motor.  More updates soon.

This robot uses two SPDT (single pull, double throw) switches, antennas, motors, and a battery pack. The antennas are connected to the switches, and so when the … Read more

A Robot Operating System

We at RobotBASIC are currently working on a RobotBASIC Robot Operating System (RROS).

The full RROS will manage almost any type of sensor allowing hobbyists
without an electronics background to build and program sophisticated
robots.  The RROS will probably be distributed Open-Source to allow
expansion and customization.  We will even allow users to share their
modifications through our web page.  The LIGHT version is requiring
sensitive coding that will not be appropriate for modification, so it will

This robot uses a beam styled solar engine. It stores up electricity in the three capacitors until it has enough to twitch and move. Hope you like it. Read more

Robot Building Time

I just wanted to start a discussion about how you find time to build robots. I know that I love building robots but sometimes I can not find any time to do this hobby. 

This is my first robot. I build it in a few hours and it it most mechanic. The bot is made using two servo's and a few pieces of wood and plastic.   Read more

Are you ready for the next LMR robotics challenge?


Are you ready for the next LMR robotics challenge?

After the success of my last game Cross the Gap. We had to give you guys another challenge of equal difficulty for you to rack your brains around. Its your chance to come up with creative solutions to win robot related prizes! This time we have asked a guest game official to be the judge of the event and to pick the game winners.


The Game:

follow light, knuckle walking,self recharging, etc.

Complete Newbie - College Project - audio question

Hello all,

I am completely new to robots and it seems like it's gonna be a lot of fun.  I am in a college class right now with a project of designing a robot.  Here is what I know:  We are using parallax microcontroller (I think... Board of Education Rev C), and I have gotten familar with the basic terminollogy.  My team plans on making a simple bot like the start here version, except bigger, with tracks, a nice cover, and some lights.  However, we really want to incorporate some audio clips and music...

Make: Taiwan - Arduino based Robot by Jay Yu aka hardmouse

I stumbled upon a page written in chinese by our member hardmouse for Make: Taiwan. It shows a nice robot featuring an Arduino and my Robot Builder's Shield, with a lot of personality as hardmouse is usualy building. Since he did  not share it with us, I thought of doing it myself. I suggest you guys go to read the chinese page in Google Chrome (it will offer to translate it for you) because you'll have a a good time trying to understand the funy way the words are arranged in chinese.

this is one of my oldest robot named Naltz created on May 3, 2009, i have posted it on my old wikia page, it's now gone because i used the parts for my other robots. but i have created many of this things because it's mechanism is very simple, and BTW, most of his hardware are from cereal boxes that had been drawn for it's face and for the linkages.

so what does he do? well, he can talk, his mouth moves like a marionette or a ventriloquist dummy,and he has sounds from an old toy.

here are some pictures:

Do anybody here build robots on commission?

Hi there,

Forgive me if this is not the right forum to ask this question. But I am actually looking to have a reasonably simple robot created on commission. The robot essentially just needs to be able to play a drumstick at a given velocity, a given amount of times - with a given amount of seconds between each hit. The robot cannot make any noises while hitting, since it is intended for scientific recording purposes, so in essence it needs to be almost silent.

For multiple type sensor robots which is better

For robots that have multiple types of sensors, like adding touch sensors, light sensors, temperature sensors, and a mix, which is easier, Picaxe or Ardunio? Or is there a better microcontroller or setup? I know Lego's NXT has these abilties, but I wanted to know what other setups are out there that work really well or are the easiest to work with or put together.


Welcome LMR members, to my newest robotic top secret project, THE PROJECT RNGTN, which is not top secret anymore.

so what about it? well i have created this to see if my analogue neural network circuit's gonna work which will be using as it's brain, and i also created this as my desktop pet, but why orangutans? well orangutans are being endangred in our times and they look funny.

Robot chassis

Hello everyone! Now i finished my robots chassis and i want to show it to you.

First picture is front of it:

And secon is from left side:

And these are wheels i may use on it:

And parts are taped with two-sided tape.

Picaxe Roboshield

I think to design robot shield with Picaxe 14M.

It has 14M CPU,L293D motor driver,Memory circuit  24LC32, programming input,male headers and some else parts.

Do you think it can be good?

Sensor seeking.

Let's Make Robots! Hello LMRians! I ordered some parts and i order more in few weeks.

I want to do my own sensor using LDR,IR led and normal leds. And yes, it's going to be something like AmandaLDR but not exactly same.

The sensor is going to my mini sumo, project what i'm working for. It's using Picaxe-08M. What do you think about it?
