Gluing/Melting the Plastic on the Dagu Rover 5

Do any of you know what kind of plastic is used to make the Rover 5?

It doesn't have the "feel" of ABS. My guess is it's polystyrene.

Plastics for robotics

So I'm trying to figure out how to best manage the funds I have for purchasing some construction material. I've decided to go with some plastics and lightweight thin aluminum I can cut by hand.

The issue is, I don't know what the different types of plastics have to offer in terms of machinability and robotics platforms, besides Expanded PVC and Polymorph, which I have worked with in the past and still have some pieces left, but I don't care much for working with those materials at the moment.

Making parts

I spent Thursday night making hubs for new robots.  Enjoy the video.

DAGU will now stock polymorph and can offer you 1Kg for $22 USD. Admittedly shipping cost will increase that price but if you are ordering several other parts from … Read more

Vacuum forming plastic parts.

Heres a few photos of my home made plastic vacuum former and its maiden test. If you don`t know what vacuum forming is check here, and youtube.

Essentially a sheet of heated plastic is placed over some kind of mould which then has the air sucked out from underneath it. The soft plastic schloops to the shape of the mould and when it cools you have yourself a robot part. It really does sound like schloop if you`re wondering.

Polyplasticy goodness

Been rummaging around every local store in search for the perfect container for the M134 controls (read lunchbox)

And so after heavily customizing an ikea 'lunchable-accessories' box I happen upon one of my favorite mischellaneous electronics sites, the one where you put all the crap that really doesnt work in a shiny aerodynamic case that makes whatever whizzbang youve made look really professional, and as an added bonus make anyone operating it and not getting it to work feel like a complete idiot.

Plastic thats invisible to IR light?

There are lots of great and interesting little robots on this site and on the web, but so many of them use the sharp IR detectors that they all start to look the same. I wanted to do something different and a bit more aesthetically nice, so I thought what if I could get some plastic thats transparent to IR. Then I could hide the IR sensors behind them and completely change the look.
