🚀 Esta terça-feira prevê-se o lançamento do Ariane 6. Um dos primeiros "tripulantes" será o ISTSat-1, do Técnico Lisboa! Este será o primeiro satélite desenvolvido exclusivamente por estudantes portugueses a ir para o Espaço 🛰️ 🇵🇹 Mais informações ⬇️ esa.int/Enabling_Suppo…

🚀 It’s launch day for #Ariane6 #VA262, taking Europe into a new era of space transportation! 📺 Watch live on YouTube from 18:30 BST/19:30 CEST 👉 youtube.com/live/B0oFpOJaI… 🚀 Liftoff scheduled for 19:00 BST/20:00 CEST. 🔗 esa.int/arianelive

Lunch and deployment of the satellites went without a problem! Congratulations to ArianeGroup and thanks for the ride! #CubeSats #ESA #ISTSat #IST #space

🚀 Ariane 6 update: first signals received from istsatone and 3Cat-4 UPC NanoSat Lab! 🥳 🔊Take a listen to the beacon we received from ISTSat-1! With this confirmation, both CubeSats from ESA Academy’s Fly Your Satellite! programme are now ready to begin their early

Progress on my active illumination multispectral imaging system: - 1/4" Tilt holder ✅ - Backside M3 camera mount (see lense in middle of the light)✅ - Light controller HW+SW ▶️ - #KR260 side camera acquisition ▶️ Stay tuned for first test images! #CV #camera #diy #agriculture

Progress on the Multispectral Illumination driver board: has 8 LED drivers on their own little board to drive 8 independent channels with up to 750 mA each. The drivers I choose are the ILD8150, a hybrid control #LED buck driver. #light #diy #hobby #cv #vision

Look what arrived just in time for the weekend (don't know if I'll have time to actually test it)! The new tiny 360° LiDAR from AliExpress that is doing the rounds on Twitter! Size comparison with a previous one I got, and that are also very popular for their price. #Aliexpress

Working on integration, fitting the #KR260 on the buggy chassis (WLToys 124019). Nice large acrylic plate as base! #AMDPervasiveAI #AMD #robotics #agriculture

It's coming together, first open loop vehicle control tests. Servo and motor controlled by the #KR260 through a custom overlay with Timers/PWM IP and using #PYNQ. Next integration it into #ROS2 with twist commands! #AMDPervasiveAI #robotics #PID #control #adventure #hobby

Newest update, getting many smaller tested things working together. Reading RC commands from the RX over SBus on the #KR260 and publish them as twist commands in ROS. Motor and servo controller now also in a ROS node, listening to those twist commands. #AMDPervasiveAI #ROS2 #DIY

Well this is an unexpected and interesting acquisition happening! Looking forward to see what "make electronics design accessible to broader market" means. I doubt it will get more expensive

First experiments and results from the Mini #lidar from #AliExpress. Based my code (in #Python) on work done by でべ (github.com/devemin/Unknow…) and Vidicon (github.com/Vidicon/Mini-3…). Good initial results (indoors), very quiet operation with near zero vibrations. #robotics

First test and calibration images with the multispectral imaging system I'm working on. It uses 8 LEDs with different colors/bands to achieve the spectral selection. Images taken with RGB camera and calibration target is PTFE/Tefolon tape covered square. (Ignore center image)

Question to all the #robotics people here. What communication protocol/interface do you all use to communicate with your robots? E.g. between MCU and main board and with the offboard PC? #ROS2 #mavlink #px4 #mqtt #arduino #raspberrypi

Interesting result, majority using #ROS2 only! You might wonder what prompted this pool? I'm planning on making a 3D application (and try out #Godot) to view/control my RC car robot (w. #KR260). ROS seems ideal, when using a network connection and #linux, but a pain otherwise...

I'm so far unable to use #ROS2 in #Godot, seemed simple: github.com/flynneva/godot… or github.com/yukkysaito/god… Neither work for me, they fail at creating a ROS node. Now either I'll switch to #Unity3D or try to make a similar system used in Unity in Godot: github.com/Unity-Technolo…

MAJOR progress in integrating #ROS2 with #Godot! Taking the #Unity3D approach by porting Unitys ROS-TCP-Connector library do Godot. Took a few days but basics are working! ROS side ROS-TCP-Endpoint is untouched, making the ported Godot version an alternative for the Unity version
