Speed holes are a good way to lose those last few grams - I've done that on just the base plates of some of my bots and saved a couple of grams there.

Solderburn's looking good!

Had an interesting week. I found out that my soldering iron had died, so I had to rush buy one off amazon XD. Another thing I found out is that the titanium I have doesn't seem to like sharp 90 degree bends (or at least, the way I was bending it), and was shearing along the fold. So I'm going to sti...

More axebots!

Will it be at AWS60?

That's the plan! (Assuming I get it all ready in time )

I haven't had the chance to wire it all up yet. I should have time to do that this weekend. I'm planning on having translation on the right stick (ELE for forwards/backwards, AIL for left/right) and use RUD for turning. I've worked out how the wheels should turn with either left stick or right stick...

I think for AWS 60 I'll just use two Arduinos, one for each DRV8833. This will let me re-use my existing code to PWM in both directions to some degree, so I can focus on getting the mechanum wheel design to work. I've assembled the wheels and printed the chassis off. Temporarily fixing the component...

That motor doesn't look healthy!

Looking forward to seeing Solderburn V2 in action!

I thought I needed 2 PWM pins per H-bridge :S *Checks Adafruit DRV8833 documentation* Huh. That makes things a bit simpler! So it looks like I only need 1 PWM pin per H-bridge - the Arduino Pro Mini has 6 so I'm good then, thanks for pointing that out! Each DRV8833 board also has a sleep pin, which ...

The plough will be hinged, so it scrapes the ground, but alas, I won't be able to power the plough - there's just not enough room or weight to do so!

So, CAD work has progressed, I now have the design of the whole bot and have a chassis printed off ready for assembly. https://i.imgur.com/zy3wB9O.png https://i.imgur.com/OY3srQp.png It prints off in a single piece with no supports, taking nearly 8 hours! It took me a while to settle on the design, ...
