Let's Make Robots!



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?

My first Arduino SHR


Hello LMRians. I'm now super exited as most of my robot parts have finally arrived!

These parts are going to be used for my first SHR. The brain, if you would like to know, is an Arduino-based microcontroller.

It is indeed the Ubotino Controller V3 and measures at a mouth-gaping (for me that is) 5 x 5 cm!

This board can be bought by our well known Ro-Bot-X at his online shop : http://robotxdesigns.ca/

Here are some very bad pictures of the parts :

Battery help



What is the difference of a 9v battery and a battery holder that can hold 6 aa batterys 3 on each side? (it comes out to have 9v) Which one is better for the arduino or any other microcontrollers??

Driving motors not working

I got my Picaxe kit in today and i was hooking everything up when i tried to get it to drive though, the motors were not working.

I put in High 5 and low 4 and high 7 and low 6 in my programmer but the wheels did not even move one inch HELP! :P

Adafruit motor shield, just running one motor

I have looked at the tutorials from adafruit, such as this one:  http://www.ladyada.net/make/mshield/use.html and I can include the library in my program, I tried the examples and I get nothing. I am using 7.2 volts for my power supply and the motor is from an rc car. I have tested the motors with a different h-bridge that came with my DFrobotshop rover and it works fine.

What batteries to power my Arduino robot.

I would like to know what type of battery setup I should use for my robot. I have 6 AA batteries powering my motors so it's just everything else... which currently consists of...

Arduino UNO

SN7...etc.   H bridge motor driver chip

Mini Servo

Sharp IR sensor

piezo buzzer?

hello LMR, can i ask a little question? what is the simplest circuit of a piezoelectric to produce a buzzing sounds?

Is the POP-BOT arduino microchip compatible with the BOE-BOT developer board?

I have an Inex POP-BOT which came with an arduino-like microchip, and was thinking of getting a BOE-BOT, which uses a Board of Education with a BASIC stamp microchip attached to it. Now my question is, there two chips seem to look identical in size, and can both be detached from their respective developer boards, so what I'm wondering is, would they be interchangeable?

Here we have Boxxy, my SHR. I had originally intended to give it a nice plexi-glass chassis; however, I chose instead to use an old cellphone box. There's something … Read more

what board



im new here and i am still very young (17) and i would like to learn how to build robots so i may get introduced in this category.

is there any way of education (i preffer in holland) to learn all about robots? and if there is (even if there isn't) i would like to know wich board you recommand to use ALSO for future use.. like the professionals do! picaxe andruino or maybe somthing else

i do know programming and its C++ is not too hard for ME xD


soo bring it on thankks alot,
