The good news is that Nathy has been doing some driving practice in preparation for tomorrow’s “marble test” at the House of Marbles.
The bad news is that PiDrogen1 has suffered a structural failure:
The back axle, which is made from 3mm acrylic, has cracked. It is the first victim of Nathy’s enthusiastic driving style. Still, that’s what testing is all about… Right?
Luckily for us, Exeter Fab Lab is open late on a Thursday night. So here is the new, simplified, surely stronger replacement part:
All we need to do now is rebuild ready for tomorrow.
There was much excitement and celebrating yesterday at the PiDrogen works. We received word that our application to join Pi Wars 2019 was accepted!
We’re in! Whoop whoop!
Uh oh. Gonna have to make something work now!
Double Uh oh. Gonna have to make up for Mother’s Day too.
At team PiDrogen we can’t make up our minds whether we like wheels or tracks best. So we decided to try both. Our wheeled chassis works nicely and we’ve had lots of fun driving that around. So now we have cobbled together a prototype track unit from the Lynxmotion 2in track components that we picked up from Robot Shop UK.
Actually, calling it a “prototype” might be setting the bar a little high. But building this has allowed us to work out the general dimensions of the whole unit. Now we are free to get back to Fusion 360 and edit our existing design. Once that is complete we can laser cut some 3mm acrylic sheet and build a test machine.
We can’t wait to put our two chassis designs head-to-head!
Oh no, Nathy is distracted by his Flybrix. Now we have no driver. ☹️
No longer a pile of bits. Now it’s a fully functional PiDrogen! 😀
We’ve been laser cutting and 3D printing at Fab Lab Exeter and now we have a pile of PiDrogen bits. Time to get the screwdrivers out. 😀
So here is the website for PiDrogen, and I guess this is the first blog post. Assuming (hoping) we get accepted into PiWars 2019 there will be many more to come, documenting a hectic six months of robot development. Fingers crossed!
