LEGO HUB-ee test 1

Just a very quick video snapshot of our prototype HUB-ee PCB designed for LEGO Mindstorms compatibility.

Arduino and HUB-ee powered balancing bot

Just stumbled across this robot project via google images. A balancing robot made with two HUB-ee wheels and an Arduino™.

New stuff

Details of our new shield for Arduino™ is now on-line, along with a new cable breakout board that incorporates open collector drivers outputs for the sensors. This board, and the revised shield that also includes open collector drivers, should solve any sensor reading problems that people might have had when interfacing to 5V micro controllers.

Unexpected interruptions

You can never do enough testing, but unfortunately when it comes to a commercial product it can also be a case of ‘ship or die’. We did lots of tests on the HUB-ee wheels, resolving various manufacturing issues along the way, and when everything worked great we put them on the market. Then one of our early adopters got in touch with an issue – the quadrature encoders didn’t appear to work properly.

New Video - Load testing

Someone asked us about how much load our HUB-ee wheels could cope with - so we thought we would do a quick test ... We built a little flat top bot with four wheels and a couple of IR distance sensors, and put a 5kg tub of stones on the top to see if it would cope.

With the first test we used the speedy 120:1 wheels -- The robot moves forward quite easily, but the wheels stall when it tries to turn.

Construction Ideas Updated

We just updated the construction ideas page with links to the design files for the TrikeBot from our homepage. No instructions or help files yet, just the cutting files for anyone with a laser, and a desire to try and figure it out themselves.

Sparkfun New Products

Just watched the excellent new product post by Sparkfun - they really did a great job of demonstrating the idea behind HUB-ee wheels - A real time robot build on camera - shows off how easy they are to use.

Watch the video here:

New distributor

The weekly Sparkfun new product post is approaching so I checked their new product page in anticipation ... well, they sure look familar!

So we can now add the magnificent Sparkfun Electronics to our list of distributors - look for HUB-ee wheels in their robotics section.

Stocktastic!

Finally, after several months of delays, we have our first batch of stock. Now the assembly work begins in earnest.

Getting injection moulded parts made in China is a tricky business and it nearly went horribly wrong for us - more about this later.

CreateBots - The Creative Robotics On-Line Store

We have just opened our on-line store:

www.createbots.com

CreateBots

It sells all the products we make so if you wanted a part that our distributors don't stock you can now come direct to us.

Whilst we test out the store and our order fulfilment process we have restricted sales and shipping to the UK only. Shipping to EU member states, the USA and Canada will come on-line shortly.
