Let's Make Robots!

Small

I like to work on multiple robots at one time (it gives me time to plan features/programming for the other robots.) This little bot is a quick build on a single CD … Read more

Mini Robotic Shield

 

Make your first robot is a fun thing. Forces you to use creativity to solve those small problems. But not everyone has the space, tools (simple as it may be) available or sufficient knowledge to make your first robot from scratch, it makes some people give up in the early days ... fair will then prevent them to have fun as we make our robots? NO.

Ideas needed for a quiet, high quality, small form factor chassis, wheels, and motors.

I'm looking for a source of a small (think deck of cards size) chassis for a robot.  I'm not interested in two wheel or cheap robots, I'd like a decent aluminum or plexi chassis with some higher quality motors and wheels.  Anyone have an idea or recommendation?

New LBD geared motor for small robots

DAGU have now released a modified version of our Little Black Duck analog servo.

This is the Little Black Duck servo, modified for continuous rotation with the control circuit removed making it into a simple geared motor with a ball raced output shaft. This motor is perfect for small robots and can be easily driven by an L293D or a controller with a built in "H" bridge such as our Micro Magician.

Picaxe Board with very small dimentions: 2.1x2.1x2.6cm (0.826x0.826x1.023inches)!
Board was Updated! Version 2.0 is done. :) I have created this small Picaxe08M2 Board so it can be integrated in small robots or other projects which require small … Read more

Micro Magician robot controller - I can finally tick the project complete box!

I started designing this controller in December 2011. After 4 months and 2 previous revisions it will finally be shipping out April 2012. I think this is DAGU's best Arduino compatible robot controller yet!

Designed for small robots using small batteries, the Micro Magician is a 3.3V controller running at 8MHz.
Working from 4.5V to 9V means this constroller can run from a single LiPo cell or 3x NiMh batteries.
Reverse polarity protection means no blue smoke if you get your power wires crossed (reverse polarity diode rated at 3A).

Uber cheap build idea, needing input...

I'm looking to build an uber-cheap robot arm, with the purpose of just sitting on my desk and picking up whatever i want it to... Probably stick with a basic control (independent forward, off, reverse switches on each motor) setup. What i'm trying to figure out is, I'm planning on using a standard 3 wire (forward, ground, reverse) style motor similar to that found in a cheap rc car, yet i can't find any places to buy them, except in the cars. any sugestions?

nanoDuino, sumo and soccer bots

Hi Everyone,

I'm starting with some new projects.

The first one is nanoDuino, an ultrasmall arduino, based on patrickmaccabe's one. This one has all the input and output's pins broken out and the sockets for FTDI and ICSP cables. It is 18,5x20,5 mm:

Wireless camera advice

I would like to implement a camera in my upcoming robots and I was wondering what is the best small camera on the market. For now, I think this one is good enough, but it still seems a tiny bit too big: http://www.robotshop.com/ca/draganfly-eyecam-video-system.html. Is this camera worth the money (I`ll probably use it if it is) or are there better/smaller ones?

what is wrong?! ..and what can i do!?

okay..         so i just finished my new robot(8 servo quadropod)and started makeing a test program.   when the test program was done i downloaded it to the picaxe and it worked! then i started to try out use the srf05 to see if it was plugged in the right way! so i made another program and tryed it and that worked too!

Mini Biped

I've been wanting to see something like this for a long time, and have never been able to make it.

A couple of people probably know games like WarHammer.

For those who dont, WarHammer is a stratagy game played with mini figurines, out of a Fantastic/Midivel times. Those figurines are generaly abaut an inch (about 2.5 cm) high, unless somekind of Troll or something.

Workspace and Workbench in an apartment

Hi - I'm new to building robotics, and have fooled around with a breadboard with some designs found online and in books. I think i'm ready to etch PCB, solder, create a body for a robot, etc etc - but my problem is that I live in an apartment and don't have a garage. Space isn't really the problem, i've attached a picture of where I want to set up, but the noise is... and also how portable everything is. i.e. when guests come over i'd like to move everything out of the way quite easily.
