@rpimagazine Happy #makermonday also from me. I continued with learning the ArUco Code. In my project I am able to reduce the size of Markers form 18cm to 6cm. Next step is to build a pacours with different Markers and every Marker has his own driving command.
#Pi-Zero 2W and #opencv

@rpimagazine In Feb2025 I sowed my OneEye Roboter https://t.co/wYVjLuaWoS
Now I am playing with opencv and ArUco Markers. Setup is streaming the video via udp FFMPEG to my notebook. Analyze the frames and send the correction Data via Sockets back to the PiZero 2W

@rpimagazine Hi #robotMakers and Pi friends. in March i posted the first video of my "oneye" evaluation robot. During the last weeks I "explained" to him to decide where he is not allowed to drive inside is a Pi-Zero 2W, PiCam and 1 ToF

@kevsmac Fantastic.
I printed a XXL Mouse Wheel during the last days. I need this for my Lawnmower to navigate through the Menu. The encoder ist a KY-040.

@rpimagazine Hi #MakerMonday my weekends are always dedicated to my Lawn Mower Robot projects. This weekend I completed the GPS-RTK basestation. LC29H(BS) and a 👆Pi Zero W V1.1 is included. Is very cheap and works efficient. The python Code is available on https://t.co/JPZvtbTmO4

Do you remember?
today I assembled the first of the two Front- Omni-Wheels planed for my 4WD Lawnmower with BobyCar top. My Prusa-Mini did the job very well

One of my robotic lawnmowers will get a BobyCar top. It will be a 4WD mower. I've sketched an omniwheel 150mm diamter for it please cross your fingers that it will work after 15 hours of printing. @kevsmac I will try TPU for the small 16 rolls

@kevsmac @waveshare00 @viamrobotics Use one of them as camerastativ operated from a pi

@moaazsidat I would say theese omniwheels working fine. lessons learned today: if you will turn / spin the robot, the result is the best, if the front wheels have 0.5 rpm of the rear wheels.

@rpimagazine Hi today it's very stormy #MakerMonday last week you saw my small #Tiny-4WD with front omniwheels https://t.co/00lkWL3iJJ
in the last few days, I implemented a BLE remote control. Both devices have a Pico W inside. You can clearly see that the omniwheels do their work very well

[Ulli Sundermann @ullisun58]

I never printed TPU yet. In order to realize Wheels fro my #Tiny-4WD I used sealing rings of an installation pipe. I will create a drive Unit for my #Tiny-4WD Rear wheels are the "normal" wheels, the front wheels are 3d printed omniwheels.

[Ulli Sundermann @ullisun58]

@moaazsidat I will report soon. Until now looks very Well. During the next days i will connect them to the electronic . Then i will share some clips

@rpimagazine I've been working on my #Tiny-4WD with omni-wheels on the front axle. The 3D print is complete, everything is assembled, and the first test has passed successfully. Next milestone is implementation of an OTA and Webserial functionality

[Ulli Sundermann @ullisun58]

@rpimagazine Hello #Makers on a beautiful autumnal #MakerMonday I worked with my tiny 4wd robot. The robot should become a replaceable drive unit and I will get a little more familiar with programming the Pico W. Especially with regard to OTA updates Currently the omniwheel unit is printing

[Ulli Sundermann @ullisun58]

@rpimagazine The Day after #MakerMonday. Remember my last post https://t.co/T2IH0Y7wlb I've finished my research. Here are two runs of my MINI PiMowBot with my Pathtracker based on ODO-Data and BNO085-Data Next week, I'll install it on my big mower. Cross your fingers

[Ulli Sundermann @ullisun58]

@rpimagazine Great #MakerMonday

Last Monday, I shared my tests with the BNO. https://t.co/G20pLBo1if Now I'm able to record the path of the small test mower. Currently, only as matplotlib png during the next few days, I plan to create a website with live tracking

[Ulli Sundermann @ullisun58]

@kevsmac @rpimagazine Great job Kevin. Which tool you use for sketching the PCBs? And is a video of your flying Pico Drone available?

@rpimagazine Hi #robotmakers worked with a #PiZero 2W and a #BNO085 I'm very pleased with the stability of the BNO values. Hope you can see it in my short video. I mounted the BNO on top of my MINI PiMowBot. The Video show my calibration Process Next Step: Implement it in my LawnMower

[Ulli Sundermann @ullisun58]

@TGD_Consulting @rpimagazine @Raspberry_Pi Verry cool looks like an industry product. Respect What is the role of the INA board inside?

@kevsmac @Prusa3D Okay great, I will also run a test with TPU during the next time, I thought the 0.4 nozzle is to small, but if it works for you, should also run for my prusa mini+
