Code name Iron-DR – Part 1 – The Bits

So as some of you may know, I have been in to electronics, mechanics and all things relating to robotics since an early age. My later life has taken me on some great adventures and I now have a wonderful family but this has also taken me away from where I started, where my roots are, the building, inventing, tinkering that is robotics.

So over the last couple of years I have been collecting parts, from bits out of skips to cheap parts off ebay and amazon, all gradually building up an idea in my mind as to how and what this robot will do and what it will look like, although the later i’m still not sure about.

So it started with some PTZ motors i got out a skip, thinking hmm these would make great super heavy duty servos , these are unstoppable by hand on even a 12 Volt supply and they are rated at 24 Volt. They also have built in limit switches and potentiometers, so coupled to an Arduino and a bit of code I now have one large, 2 degree of freedom servo, great stuff.

These PTZ housings are probably one the best scores I have ever had from a skip, although they were coated in a thick layer of aluminium oxide from having spent their life out side on the side of roads, damn you road gritters.

So next I needed something to drive this thing along. I thought long and hard, searched everywhere but still have never found a reliable solution at a low cost to make tank tracks, that’s what I would really like, by the way I get a kick out of recycling things, you might of guessed I don’t often pay for things  when building robots. So tank tracks aside, everyone has started buying hover boards, although they don’t hover, they are a great source of large brushless motors, with no need for gearing and incredibly good power output to consumption, ebay it is, and a week or so later a box with 4 of then in arrives, quoted as being 500 Watts each, that will do the job!

Other bits collected, from skips, lithium battery packs from laptops and electric bicycles, check out the other blogs here to see about building up the battery packs for this project.

I was also able to score the below aluminum bars, which are great as they had loads of fitting attachments on them and makes things really easy to make, did I mention its aluminum and looks cool, lol.

anyways that’s all for now, part 2 will be soon.

Mechatronics – Engineering the future

Mechatronics, IoT, and Industry 4.0

Mechatronics is a term which is popping up frequently these days, by the way, it’s not new. If we recognise the first reference to it, when Japanese engineer Ko Kikuchi combined the words mechanical and electronics in 1969 then it’s been around 47 odd years.

In the UK the first MEng course in Mechatronics was established in 1985 and 3 years later in 1988 the first graduates appeared.

Multi-discipline approach for Mechatronics

So what is Mechatronics and why is it of significant importance now? Well actually it’s always been important but with IoT and the Industry 4.0 movement it’s now a go to term which captures all.

Mechatronics brings together an integrated approach to engineering which involves electronics, mechanical and computing disciplines. Most production and manufacturing facilities will employ a high degree of Mechatronics. The division between electronics and mechanical engineering is now more blurred, the outcome of this is a more integrated approach to engineering in general.

With the advent of Raspberry Pi, Arduino and similar single board computers more people are learning to code and looking at wider applications through the open source approach than ever before. Go to any Maker Fair, Fab Lab and Hacker Event and you will see Mechatronics in action.

So what is the scale of Mechatronics?

Well think about motor control, from large 3 phase inverters to small micro-processor control boards and you can see the scope of Mechatronics, even in this technology field it’s large. Now consider all the machine tools, such as laser cutters, pressing and punching tools, mix this together with packaging and conveyor systems and you can see that it’s huge, now add the IoT equation to the mix and we have something which is truly massive.

This is great news if you specialise as a Mechatronics Engineer, you are very employable and more in demand than ever before, seriously, if you want a career in engineering it’s worth considering Mechatronics. For here the field is open for Robotics, Aerospace, Motion Control, and whole host of engineering possibilities.

Moving forward it won’t be long before we are including Augmented Reality as a major part of the engineering mix (topic for another day).

Let me quantify the greater need for Mechatronic Engineers by highlighting the basic requirements of IoT, DATA.

Data is King in modern manufacturing

No big surprise here that the key to IoT is data, but consider how that data is gathered. First of all which data point’s do you need to measure to give a logical coherent output. What do you do with that data once you have it, how do you process it to make sense of it. The reason for all this data is to build efficiencies and cost saving into the system, this plays perfectly into the multi-discipline world of mechatronics.

This might sound too simplistic but who better than a mechatronics engineer to help companies remain competitive in an ever increasing environment where every second counts and inefficiencies cost millions. Asset management is reliant on great system integration and communication between processes. In industrial environments this can lead to a reduction in un-planned maintenance, with orders on specific products being placed before breakdown occurs. In manufacturing, parts are available on assembly lines just as you need them.

Robots and alike wont take over the world any time soon, buts its clear to see in a modern world they and mechatronics play an every increasing part in the world we live.
