Update 6: Pan, tilt, see... Vision challenges in progress...

2018-3-12

Another weekend... and yet another, smaller than expected turnaround... but we have made progress. As mentioned in the last post, I have been racing to complete the Pixy camera integration before I finalize the routing logic for Pi-o-steer. I thought this week would be it, but we had a scope creep... we ended up designing, 3D Printing and assembling a full Pan-Last mechanism. On any other day I would have considered that a big achievement but in the big scheme of things it wasn't as big.

Two weeks have flown by since the last update and as I sit down to write this I realize, inspite of what seems like quite a bit of progress, we maybe falling behind. Anyway, we made some progress in the last couple of weeks. Following are the highlights in no particular order in which they were achieved.

Update 3: We are going to PiWars 2018!

2018-2-7

Happy new year everyone; Oh wait, it's February already (how did that happen O_o ?!?). January just flew past and among all the excitement of New Year, squat in the middle of NDC London, I got the magic email from Mike Horne, one of the organisers of PiWars - there had been a drop off and our team had been bumped into the qualifiers list. So team Pi-o-steer is going to PiWars, Yaba daba doooooooo! This news provided impetus to my sagging morale that had seen me procrastinate about the bot for over a month.

Putting together a digital photo frame using a Raspberry Pi

2018-1-12

I have had this idea of a portable Pi tablet style computer for a while. My first touchscreen purchase was specifically for building such a portable Pi device. However the driver for the WaveShare display went bust and with that it got consigned to my heap of "Todo later" projects.

PiWars Update Two: Steering Geometry, say what now?

2017-12-2

As I mentioned at the end of my last post, I was planning to re-design the front motor mounts and the entire steering mechanism. While this would cause a delay, I thought might as well get as deep as we can given we didn't have any time pressure. Even if we got the bot moving with sensor input by Christmas 2016, it would leave enough time to hone the software for guidance. Though chances of getting the nerf dart launcher built looks a little sketchy now.
