Updated this list of open hardware #robot electronics a bit github.com/samuk/list_o...
Messing about with robots continues, this one doesn't work yet, pending github.com/Agroecology-... #ros2 #agbot #sowbot #robotics
I think you're confusing 'shouldn't' and 'can't'
Attacking another state with no legal basis for example; is a bad idea, It doesn't mean that it can't be done.

I think Nichrome wire is what you're looking for with a lead acid battery (I wouldn't risk shorting Lithium) www.amazon.co.uk/nichrome-wir... or if you're feeling flush uk.ryobitools.eu/power-tools/...
Dev was friendly and interested in their Discord too which is a bonus
Although saying that it does seem to be running out of momentum rather than gaining it github.com/openrr/openr... maybe there's an active fork
It's early days for it I think, but maybe in 12 months is my thinking. Bring up ROS now and wait with a working robot rather than a pile of parts? Second link should have been github.com/copper-proje...
State of the Browser is sold out in-person, but £20 will buy you a whole day of online talks by industry experts.

Current thinking about a 2026 ROS bringup github.com/Agroecology-...
Then gradual migration to github.com/openrr/openrr + github.com/openrr/openrr as they (and hopefully I) mature.
Project is sowbot.co.uk
Worth it, or just start as you mean to go on? #ros2 #rust #robotics cc @sequoia.farm
Aaand let's completely refactor that for Jazzy, some new naming conventions and abandon Nav2 sowbot.co.uk

robot control panel with joystick and map of london with a location pin in it
Software stack for it starting to come along too, pretty outdoor focused RTK GPS etc github.com/Agroecology-...
I've even got a WebUI

you design 2-layer PCBs because you're good at making efficient layouts. I design 2-layer PCBs because I'm a cheapass. We are not the same

Been working on the robot brain.. Some docs for it here sowbot.co.uk plan is to build an #Opensource Agbot

✨ New bonus episode! ✨
I asked roboticists what is well known in their field of robotics, but outsiders find surprising. Their answers touch on technical challenges, societal impact, and even students' expectations.

Tomorrow my plan is to
- fork a version of the controller software for the 8 channel servo board.
- put an 8 channel servo board on the robot.
- work out the extents for the servos
- modify the servo board with walk sequencing software.
- finish the robot.
Hi, @octostudioapp.bsky.social and @cocubefun.bsky.social. We love this photo with the MicroBlocks logo in the back.
playback from realtime trainer recording!
I can also do waypoints that are linearally interpolated. (realtime is just a fast stream of the same interpolation)
New Stable Release! Try it out at microblocks.fun/run/microblo... or install from microblocks.fun/downloads/la...
This is also what made Obsidian click for me. I was *so* tired of learning to write in one tool and then having to move to another. Well, now it's just something living atop the markdown files that *I* own.
