Pico platform dev kit for the sowbot.co.uk project. Still some slightly annoying software bits to do before it works

Slightly more grown up looking robot nonsense

N3RD first day out did well. #maker #robot #fyp

Rearranged the sowbot.co.uk 'brain' to get it to fit inside a waterproof enclosure #robotics #ros2 #modular

Nathan Charles and Utsav Adhikari will present their work on “ROS2 GPS-based Autonomous Vehicle Navigation in the Agriculture and Livestock Space” at the 2026 TXST STEM Conference: From Lab to Landscape: genstem.cose.txst.edu/txst-stem-co... #ros2 #AUV #GPS #engineering #research #txst

This might be interesting for open hardware enjoyers www.arduino.cc/product-vent... (assuming it actually is open hardware once released)

Updated the 'brain' and 'pico' robot BOM on sowbot.co.uk might try and get the Pico actually running tomorow

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

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

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 #Robots #ROS2 #OpenHardware

✨ 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. 🎧 Listen here: www.patreon.com/posts/bonus-... #Robots #Robotics

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.

The sin/cos differential capacitive fluid inclinometer you never knew you needed? <-- 15mm --> (balancing robot challenges)

First steps! #robotics

This is Plume, my new homemade biped robot. #robot

Given a robots oscillation is 10Hz, and its been given a fresh set of batteries. calculate the excess amount of coffee the robot has been given.

Depth Anything V3 now runs in real-time with our karl.'s camera data predicting metric depth from monocular images. With TensorRT optimization, we’ve wrapped it into a ROS2 inference node that’s ready to drop into your stack. Github: github.com/ika-rwth-aac... #Robotics #ROS2 #TensorRT

Robots don’t work. If it worked they would call it a machine. You can tell it’s a robot because it’s not doing what it’s supposed to do.

100% open hardware Robot brain starting to come together. Octa core Avaota A1 SBC, @sparkfun.bsky.social RTK, talking to @mister.industries Esp32. Next do the breakout for @adafruit.com Canpal and it's ready for @sequoia.farm motor drivers. Electronics power & via custom step down & isolation board.

Oh boy.. finally found our #Bluesky password. Here's what you've missed: - We sold through our first batch of boards! - Ordered 100 more with revisions based on user feedback - Published our first YouTube video - Got registered with #OSHWA - Revamped all of our documentation ..And a lot more!

Made a pen plotter for under $20 and some 3d printed parts. It serves up a whole web server, just connect, draw, and plot. No drivers or installs for the user, just open a browser. Full writeup here hackaday.io/project/2045... #cnc #3dprinting #esp32 #penplotter #stem

Power washed the tanks in preparation for the move. Which is a completely normal thing to do. 😂

A few fixes later, here’s the robot’s new PCB alternating power between batteries and the Jetson Orin Nano’s 19V adapter. In both configurations, different voltages are regulated for the MCU, the sensors and logic, and the motors, with a total max power of around 60W.

Looking over my motor controller to see what components are limiting my max DC motor voltage right now and I check the datasheet for the EG3113 gate driver and it's +600 volts. Like lmao okay not that one then

When I read “oh! the places you’ll go” I didn’t ever imagine that would include an underground robot boxing match, where a pair of people attempt to play rock em sock em robots with 4 foot tall unitree bipeds. Remember the first rule of robot fight club is that we turn off logging.

📢 New Episode Alert! This week, I chatted to Dr. Chapa Sirithunge from the University of Cambridge about what robots can teach us about human anatomy, and vice versa. 🤖 Listen now: www.robottalk.org/2025/11/28/e... #Robots #Robotics #BioInspired

I've actually really started to enjoy this site. There are only like eight of you who see my posts but you're all pretty cool

Made some updates to the USB-C PD circuit and pushed to github. You can view the board in this web viewer [1]. I also remembered I made this smaller than a credit card or a business card! I could use this as a cool circuit board business card. ⚡ [1] kicanvas.org?github=https...

I have made great progress on my RP2350 powered open source brushless motor (and industrial stepper) controller! This board supports up to 53v max, 30+A peak (depends on thermals), and is designed so anyone can order them from JLCPCB. I also just added USB-PD for 100W at 20V via USB-C!

Found a bit of time to play robots..

Open source has always been a huge part of robotics, and this feels more true now than ever, with a proliferation of innovative open-source hardware and software platforms that have made robotics more accessible and dynamic than ever before. Blog post: itcanthink.substack.com/p/the-role-o...

Today, I have been working on a controller for the Giant Unicorn Hat. Have written a function to move the powered fadder to a set position, using a @pimoroni.com motor 2040, running CircuitPython to monitor/control the faders and the NeoTreilis. #GiganticUnicorn
