Let's Make Robots!

UGV trainer kit - Unmanned Ground Vehicle

Typically when I hear the words "Unmanned Ground Vehicle", I tend to think of military and off-road vehicles but these days big companies are investing millions of dollars on cars that can drive themselves.

This kit is an affordable beginners kit to help students and hobbyist learn the basics. Using the Arduino compatible Micro Magician robot controller with it's library of basic control functions ensures an easy and fun learning curve.

Little Black Duck - 12g, 2Kg/cm miniature servos from DAGU

Have you ever built a robot and then found your miniature servos were not quite strong enough?
Get yourself a flock of ducks! DAGU's little black ducks!

DAGU are now selling a 2Kg/cm servo that is only slightly taller than a standard miniature servo. The height difference allows for thicker, stronger gears and a bearing to support the load.

Polycarbonate 90° bevel gears with aluminium mounting brackets

When you build robots, sooner or later you will need a 90° bend in a drive shaft. Crown gears are fairly common but the teeth are relatively small and strip easily.

DAGU have now produced some relatively small, polycarbonate bevel gears to help solve your gear train problems. Unlike crown gears, bevel gears have a longer, tapered tooth that is much stronger and harder to strip.

Magnetic servo clutches from DAGU

After years of being frusatrated by stripped gears in my servos I have finally done something about it. DAGU is now producing servo clutches to suit 8g and 9g miniature servos.

Unlike normal servo savers, Dagu servo clutches can be continuously rotated without damage to the clutch or the servo. They look like a servo horn but are a few millimeters thicker. They can be configured for both standard and continuous rotation servos. Here are some common configurations:

Micro Robot Controller

 

This is my new Arduino compatible controller for 2012.

I have crammed as many basic features as I can into a tiny PCB and even written a library to help you use these features. The ability to drive 8 servos (3A maximum) directly from the controller make this an ideal controller for a small Quadruped or robot arm.

Building the perfect Beast (robot chassis)

2012 may be the year of the Dragon for China but it is the year of the robot chassis for me. I am trying to create a new range of robot chassis's and I'd like to know what features my robot building friends would like to see in a chassis. Obviously low cost and high quality are preferable but what else?

For example size? As far as I can see there is already a range of sizes on the market. Is there a size that's missing? I was looking at some cool wheels that were about 250mm (10 inch). Would you want a huge chassis and for what purpose?

S.C.O.R.P.I.O.N. Potato cannon mounted on 6WD robot

Ok, to begin with it is just a normal SparkFun "new product post" but check out the last few minutes of the video. They mounted a potato cannon on a 6WD Wild Thumper chassis!

Who thought robots and potatoes could be so much fun?

Struggling with creating libraries for Arduino

UPDATE

Documentation of my efforts will be continued in my blog: Building a new controller - fun and games

Thanks to the help of my fellow LMR members I now have a working library. I have attached the initial library created as a result of this forum. A big thanks to cr0c0, Maus and Mogule who put a lot of effort into helping me with my code. The attached library is not the final product, I need to add more functions and examples yet (I may also need more help).

Cloud computing - the next world crisis?

I have just used my first internet based software tool and I found the number of times it could not save my changes because the server did not respond or gave a bad response to be very annoying!

When I first heard of cloud computing I thought it was a foolish idea. Now more than ever I think any company that becomes dependant on cloud computing is going to suffer badly.

Ok, this is just my personal opinion, maybe I'm wrong, here are the reasons I think it's a bad idea.

Support site for DAGU kits and products

G'day Everyone,

I have been designing products for DAGU for over 2 years now. During this time I have always tried to provide technical support and help in general here on LMR. I will still continue to do so but previously I had trouble uploading manuals because of upload limits.
