Instructables always has neat robots, try this one: http://www.instructables.com/id/FOBO-bipedal-walking-robot/(external link)

I've also found out about a neat robot building site - http://letsmakerobots.com/.(external link)

Enjoy!

I love this video - it brings together two of my favourite things - homebrew hacked robots and music/rhythm experimentation.

The Yellow Drum Machine robot taps on objects, samples the sounds, and assembles beats with them. An interesting way to use a robot, and quite endearing.

Anyway - please enjoy:

This guy has built a Lego walker based all on pneumatics, no electronics or programmable bricks at all. Granted, there is a likely non-Lego air compressor for it, but still. It is an amazing bit of work, and considering all I ever did with pneumatics was a simple 3 cylinder reciprocating engine, I am quite amazed. It must have taken plenty of time and quite a few attempts to get right!

So it has been open since before Christmas, but they did their big grand opening recently (for various reasons).

I paid them a visit to see what I made of it.

First the staff - the store was pretty busy, but the staff were friendly and chatty. They were not necessarily all Lego nuts, but they did know the product and they did help out, including answering a bunch of questions. We were buying stuff for our daughter which helped.

There is a fairly good selection of Lego, including the mindstorms and Lego Technic kit. The NXT 2.0 set was there - with quite a few stocked, as well as many of the power functions motors, battery boxes, cables and controllers - these were just on a simple plain rack so those a little more technical could grab exactly what power gear they needed.

The Pick-a-brick setup, if you aren't familiar with the idea, is a bunch of buckets arranged on a wall with scoops to measure out lego bricks, and you are charged for what you take. Very simple way if you need that many red fence pieces or some similar thing. Obviously there is only a limited number of boxes, so don't expect to find obscure or technic pieces.

There is a "make-your-own-minifig" area, where punters can select heads, headgear, tools, bodys, legs and other accessories to make a minifig, then pay to take that home. Boxes for them are provided.

Also in the store, the current flavour of the month is displayed, as we went in that was the Lego Hero Factory theme(external link).

The layout is pretty well thought out, given that youngsters will want to run around, and there was a very big bucket of duplo set into a table with two studded surfaces, so the toddlers can build towers (as our little one did). Or indeed knock each others over. Each Lego theme has a separate area on the wall, including some special bits.

There were some interesting kits I've not seen before like a minifig display case. In terms of branded accessories, there were wallets - in white with the Logo, many minifig and tiny model keyrings, Lego cups, Lego beachtowels and a white satchel. Shame none were in darker colours, and a shame that they had none of the other apparel.

In all - it is worth visiting a Lego store, there will always be something to find there, and if it is the shepherds Bush Westfield one, then there are other shops to see - they've a number of gadgetshops with robots, nerf guns and similar there.

The arrival of Lego mindstorms kicked off a wave of Lego innovation, but not all of that used official Lego mindstorms kits - some where just motors strapped onto curious contraptions, some of the most interesting being the Rube Goldberg devices, kinetic sculptures, rolling ball machines and similar.

Lego Domino laying contraption:



Early Lego marble machine:



Innovations like this have led to responses with pure Lego, the culmination being the Great Ball Contraption - GBC - This video has trains, robots, and many ball moving machines:



The GBC is many contraptions made by many Lego clubs and fans, unified by a common interface and brought together at Lego gatherings where many are joined end to end to make a circuit. These lead to videos of smaller collections like this one, filmed in a way that makes it clear it has become obsession:

Memory was once built by hand. This memory is good to understand the principles of the system, and will neither be large enough or fast enough to have any hope of being able to extend your computer.

However, understanding these will aid you in programming, electronics, microcontroller usage, and will just be plain fun. Plus it may be handy for a couple of cheeky LED circuits.

I've been considering building my own pick and place, or CNC or similar manufacturing gear for some time.

It appears that others have definitely got there first with some amazing factories, built entirely with Lego, using Mindstorms kits to pick and place and manufacture Lego models. Indeed the earliest I saw (and possibly not the earliest built), was a few years ago. So what is there?

The first I knew of was the Mindstorms Autofabrick - a Car factory.



Then this one, uses the chain links from a Lego technic bulldozer set to make a conveyor, and shows a much simpler pick and place action.



A fabulous aircraft making factory, built using 25 RCX's and 73 Motors. It cost around 8000€ to build, and took over 1000 man hours - an epic creation.



All of those, while amazing, are not as flexible as this latest offering, which was demonstrated at Legoworld 2010 in NL. It is using the NXT and is a monster with 50k Lines Of Code, running on 5 NXT's. Fewer than the 25 RCX's, but yet appears to be a more flexible setup. It is actually putting together Lego designs made in LDD - a simple CAD app from Lego themselves. Truly the greatest of these fabrication plants so far.



So what can you do with these? Build your own - perhaps consider CNC machines - or just be inspired to build something. Have a go!

Most real robots at the moment are confined either to laboratories of big business and hobbyists, or to manufacturing. But what of robots offering more domestic services and being devices you'd want around the home or to be a companion.

With robots that do dishes, make music, prepare sushi and mix drinks, perhaps these are a generation that can make it out of the labs and into our homes.

10 Robots You Can Actually Date(external link) covers these - don't worry there are no unsafe or unpleasant links in that.

Perhaps my favourite is the one that can load the dishwasher. The list forgets the Roomba, a robot that can vacuum floors autonomously.

Why not be inspired to make a halloween costume based on your favourites - either from Sci fi or even reality. Here are 2 ways to build a chicken walker - one as a robot, one as a costume. Enjoy!

What are Chicken Walkers?

Chicken walkers are robotic platforms in both futuristic and steampunk sci-fi. They are essentially a pair of robotic legs upon which a human can ride, either to allow him to carry heavier things over a distance, or to give a disabled person the ability to get around, or simply with legs and a surface as a platform to carry stuff around.

Chicken Walker robot

This video has details on a chicken walker costume (not really a robot), which lifts its legs when a wearer does. It looks more futuristic than steampunk, but the basic idea could be adapted.

Steampunk Chicken Walker Costume

On Instructables is another chicken walker costume - perhaps a little simpler - Build your own steampunk chicken walker mech (costume)(external link).

More Halloween Costumes

I've compiled a list of halloween costumes based on robots, I am sure you can enjoy building one of them yourself... Included are Transformers, Terminator, Star Wars and Gort.

One of the things occurring in modern robotics is that they are increasingly being used to wage in wars by the richest nations. This benefits them in not having to sacrifice men on the front line, as well as being able to send robots for painstaking sweeping/searching missions where the robot will spot things a person may not be able to see.

They may even be manne from a distance, flown or driven remotely.

It is a double edged sword, as while I am no fan of killing machines, or warfare in general, if it must be done, doing it without putting people in the front line might be better. Could this develop into SkyNet? Unlikely and very improbable.
