Let's Make Robots!

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?

It's been a long time coming but Mr. Tidy is finally here! He is Arduino compatible using the ATmega1280 MCU and can be programmed via the pre-loaded Arduino … Read more

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?

Building a new controller - fun and games

Friday 27th January, 2012
This blog is a an ongoing list of my thoughts, as I attempts to create a library for the Micro Magician. It is boring and should not be read by anyone :p

 

As some of you may already know, I am designing a new Arduino compatible controller for small robots. One problem with small robots is limited space. This makes sheilds, motor controllers and wires difficult to fit. For this reason I tried to incorporate a few useful devices onto a controller while keeping the cost low.

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).

New DAGU products for 2012

Well 2012 is off to a great start with a brand new Arduino compatible controller, A car controlled by your phone and a robot arm with teaching pendant from DAGU.

The Micro Magician is designed for small robots running on low voltage batteries. The controller works on voltages from 3.6V to 9V.The heart of the controller is an ATmega168 running on 3.3V with an 8MHz clock. Check out the great new features!

OddBot marries the beautiful Li Si Ling

It seems in China you must travel to the brides birth city (or a city nearby her birthplace where they keep the documents) to be officially married. 3pm Sunday afternoon we were on our way!

We had to travel 5 hours by bus from ZhongShan to XingNing to get my step sons passport. The bus had beds for the long trip which was great for small Chinese and children. Not so good for a 135Kg Aussie!

There may be times when you have a limited number of I/O pins and you want to drive a small DC motor. You could convert a servo for continuous rotation but servos … Read more
