We’re feeling really excited and lucky at PiDrogen HQ today. We just received our prizes for PiWars 2021. There’s loads of really cool stuff! Thanks so much everyone at PiWars and all those PiWars sponsors; you’re very generous! Right, where’s the soldering iron?

P21 Ready for Sidmouth Science Festival
We’ve finished the new game that we mentioned in this post. It’s a kind of desktop variant of Tidy Up the Toys. Take a look: So, hopefully, P21 is ready for the Sidmouth Science Festival. We’ll be in the Kennaway House Cellar Bar between 10:00 and 16:00 on the 16th October 2021. Come and sayContinue reading “P21 Ready for Sidmouth Science Festival”
Is this the cause of P21’s dodgy wheel?
P21 has had a dicky back wheel since it fell off the roof during filming of the Obstacle Course for PiWars at Home. The motor runs, but the speed is not well controlled, so I assume the problem is related to the encoder. After the competiton I dismantled the back axle, reseated the connectors, andContinue reading “Is this the cause of P21’s dodgy wheel?”
Sidmouth Science Festival
Each year, Sidmouth (in the southwest of England) has a science festival. This, year it takes place between the 8th and the 17th October 2021. We like to go to the festival for the rocket car contest. If you’re an avid follower of our blog, you may recall that our entries won the rocket carContinue reading “Sidmouth Science Festival”
The Results
The waiting is over; the results of Pi Wars 2021 at Home have been announced. And I’m delighted to announce that we won the Advanced Category! Here’s a link to the results, the videos we submitted for our entry and some extra videos that were made by P21’s camera as the robot performed the challenges.Continue reading “The Results”
It’s a Wrap
We don’t want to gloat or anything, but we just uploaded the last video to YouTube. Time for a GnT in the sunshine! (Actually, totally gloating. 🙂)
The Bad News & the Good News
Argh! First the bad news: we may have been too ambitious when filming the obstacle course. PiDrogen has taken a significant tumble and is now in “dry dock”. I can’t tell you what happened right now (you’ll have to wait to see the out take at the end of our obstacle course video at theContinue reading “The Bad News & the Good News”
The Obstacle Course
Yikes! It’s June. 18 days left. Better get on with it. When we record the obstacle course, we plan to be running PiDrogen’s recording strategy. This records a video from the robot’s camera and marks it up with various information, a bit like a Head Up Display (HUD). See below. The HUD reports the headingContinue reading “The Obstacle Course”
YACA5 Update
Sorry! I forgot to update the blog on the new catapult arm. (See my previous blog entry). Sadly, it didn’t make a difference on the Feed the Fish game. But I’ll explain it anyway. Nerf Rival balls are obviously made with a mold which has two hemispherical parts. It is clear to see the seamContinue reading “YACA5 Update”
Yet Another Catapult Arm
I’ve fallen into the trap of searching for the Holy Grail of Feed the Fish: that is 15/15 shots. I’ve done so many “takes” that the course has gone darker (from tyre rubber) where the robot makes a right-angle turn to line up on the aquarium! This is my latest attempt at designing a moreContinue reading “Yet Another Catapult Arm”
