The Raiders of the Lost Cam

Hello fellow Robot-eers!

I just wanted to share how I’ve finally got my test PiCam.

It took quite a long time because I searched everywhere for a good deal. I found that the options are quite limited: I could choose either to pay up to £25 for a camera on the official UK websites (like ThePiHut and similar), or to get it from China, which would take at least a month and may never arrive (this scenario actually happened to me, making me wait a month for nothing) or arrive broken.

Fortunately, I found this Amazon item which provides a good compromise between price and shipping time (the seller is in UK and it took only 4 days to arrive).

As you can see, it comes with a nice acrylic enclosure, so you don’t need to create your own holder which is very handy if you want to experiment without mounting the camera on your Robot.

It was a bit fiddly to put together the small plastic screws, but once I got the hang of it, it took just a few minutes.

There’s also a nice YouTube tutorial that shows how to build the enclosure (which is shipped with no instructions whatsoever!).

I’m now ready to try my OpenCV code on the real hardware 🙂

I hope this post will help others as well!

And so it begins…

Hubble, Bubble, Toil and Trouble!! <Evil Cackle> After months of talking and scheming, we have started this year’s build…

This year we have decided to move up to a better platform; well better than last years anyway. To this end, Phil investigated various different methods of building and settled on this…


This is basically a set of Anodised Aluminium bars in various lengths, with angle brackets to allow us to connect them at various angles.

For motors, we have moved up to these…

12v 220rpm motor and wheelsets

These were actually quite hard to get hold of, for some reason. They had them of 140 and 330rpm and 6v but no 12v 220rpm! Why 220 I hear you ask?? No particular reason, other than I bought one and thought it would be sensible that all 4 matched. Phil has the 140rpm variant and we will decide which to go with as development progresses.

These motors have sensors attached to count revolutions. We are yet to decide if we are going to use them, but it’s better to have them and not need them….

I managed to control myself and did not play until this weekend. So while at HH this month I copied the 1st one, that had been built by Phil.

Now I need to get with the program and wire the motors and Pi up. Then we can start to build the challenge code.

Watch this space….
