I always felt that the mecanum wheels we use on P21 were too large; they’re about 100mm diameter. I think they are not really suited to delicate autonomous manoeuvres. Over Christmas I decided to gamble on buying a set of these from Pimoroni… These wheels are cheaper than ones I’ve seen before (£24 for aContinue reading “Smaller Mecanums”
Back in December we blogged that our Mk1 chassis was too slow, so we had started development of Mk2. Well, here it is! In this design, the motors drive the track sprockets directly, with no reduction gearing. This results in a top speed of 1.2m/s; the same as P21. Hopefully that will be fast enough.Continue reading “Mk2 Chassis”
Our 3D printer had New Year’s Day off. But now it has a new hot end thermistor; so it’s back to the grindstone. It’s printed some chassis components for PJD’s new motor layout. Team PiDrogen is back on track! :0) Happy New Year folks!
This is going to slow PiDrogen development down. 😕
The chaps at PiWars HQ want an update… So, here it is in a blog post. PJD Mk1 has been built with some temporary electronics (which allow it to be driven by RC). We’ve been driving it around; and basically it works fine. Even the slightly risky 3D printed crown gears seem to be holdingContinue reading “Progress Update”
The apple picker I blogged about a couple of days ago is nice and it works. But I’m not going to use it. MkII is better because it has no moving parts; the robot will just drive up to the tree and the top prongy-thingy will knock the apple off the tree and into theContinue reading “Apple Picker MkII”
Apple picker in action…
Work on PJD is gathering pace. Another vital piece of the robot has been completed and is working. Now that’s done, work can start on the lower priority stuff. *I would like to say that no robots were hurt in the making of this component. However, a certain Hexbug from PiDrogen HQ has had betterContinue reading “A vital part of PJD is now working”
Hmm, possibly a bit behind the curve for this post but… We’ve been accepted into PiWars 2022 at Home! Wahoo, here we go again! :0) And here’s the robot we plan to build for the competition: For context, the theme of this year’s competition is “Old McDoofus had a farm” (Doofus is the name ofContinue reading “PiWars 2022 at Home; We’re In!”
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?
