So do you have a 24v system being charged by 12v , or is it a 2 batteries in (i belive its ) parallel for longer range. I just built mine and im haveing a hard time to figure out the charging system. Thanks and i love the project.

Why Rear L wheel is also on Pin 9? isn't that gnd? And Dir is also pin 25 which is also GND. Or are these not the pin numbers but the GPIO numbers? Sorry I'm just a little confused

Thank you for the great video, subscribed! Do you still recommend ArduRover for someone starting or are there other platforms worth checking out?

What a great video, thanks!

Really insightful build! Eagerly waiting for version 2 to understand the optimized camera system

hello sir, i am interested in auto pilot drone how i can reach you

Hello, Will these Tensor Flow codes run on Version 2 System? If not do you have the codes for those?

That's beautiful! Thank you for showing.

Looking to do something similar with a project, may I ask why you went with an AC alternator to converter instead of just a DC alternator? Also have you noticed a drop in HP after adding it?

Sensor suggestion: touch lamp on/off technology or measuring millivolts or continuity! Grass is conductive. Use A few (4?) copper wires stretched across front should give you a general idea of grass height, and left or right side. Plus it’s super cheap.

You do a really good job explaining everything. I find it very difficult to make a video like this. I build projects like this all the time but I'm terrible at making videos. So they never see the light of day. I think that your 3D printed touch sensors probably just need a slight redesign. I think those were pretty good idea. Also I would definitely add the kill switch. If you take the cover off the motor you'll find a magneto with a black wire coming off. Grounding that wire out kills the engine. You may be able to control that Killswitch wire with a transistor.

Any chance you've been able to do that parts list? i'm trying to copy what you've done, but also fit it in a kitchen cabinet under the counter. Hard to tell how big things are, how tall the fridge needs to be, etc. Would really appreciate a very specific parts list so I don't end up buying the wrong things. Thanks!

For grass height. What about angle measurements, attach some rollers with a hinge, measure the angle depends how long the grass is. Would need to be light weight as not to squish the grass to much.. great projects can't believe why you don't have more subs, your projects are amazing.

did you look at using LD2410? or any mmWave sensor? its can give you very good read and the sum wont impact it(and its low cost about 2~3$ per unit )

Next upgrade could be precise GPS, how does that work? The magician's staff with the gadget on top that makes the GPS signal cm precise. RPI lidar V2 is also pretty cheap comparatively.

Wow I didn't expect that ultrasonic sensors work well in such a loud environment.🤔

cool

I asked Chat GPT if a camera could be coupled to a raspberry pi to control a grass mowing robot. It sounded like the answer meant it would be possible. This is what it told me, if I could paste the answer here. Since I don't know a dog gone thing about how to do something like this, it seems like it could be a feasible answer to get your robot to follow a cut path better to me. You have great ideas and I loved your video. This is not something I could do, I don't have the required skill, but somone like you might be able to get it to work well. +++++++ You said: Woiuld it be possible to program a camera to identify a line of cut grass on a lawn using code embedded in a raspberry pi computer board. ChatGPT said: ChatGPT Yes, it is absolutely possible to program a camera to identify a line of cut grass using a Raspberry Pi. This can be done by employing a camera module connected to the Raspberry Pi along with computer vision techniques. Here's an outline of how it could be done: Key Steps: Camera Module Setup: Connect a Raspberry Pi camera or compatible USB camera to capture real-time video or images of the lawn in front of the mower. Image Processing with OpenCV: OpenCV (Open Source Computer Vision) is a widely used library for image processing. You can use it to analyze the video feed, detecting differences in texture, color, or height between cut and uncut grass. Grass Line Detection: By processing the images, you can look for differences in pixel values that distinguish cut grass (usually more uniform and flatter) from uncut grass (likely darker and taller). This difference in texture or shading could allow the system to follow the boundary between the two areas. Edge or Contour Detection: OpenCV has built-in tools for edge and contour detection. You can use these tools to identify the transition line between cut and uncut grass. This line can be treated as a guide for the mower to follow. Path Following Algorithm: Once the line is identified, you can create a simple control algorithm that adjusts the mower's direction to stay aligned with the boundary of the cut grass. Obstacle Detection: OpenCV also allows integration with other computer vision techniques like object detection (using pre-trained models like YOLO or TensorFlow), which could help the mower detect and avoid obstacles. Additional Considerations: Processing Power: While a Raspberry Pi may be limited in processing power compared to more robust systems, it can handle basic image processing and camera feed with OpenCV. You may need to balance the resolution and frame rate of the camera feed to ensure real-time performance. Machine Learning (Optional): For a more advanced solution, you could even train a machine learning model to recognize cut vs. uncut grass. However, this would require collecting image data and training the model separately, which might demand more computational power. Hardware Requirements: Raspberry Pi (preferably a Raspberry Pi 4 for better processing power) Raspberry Pi Camera Module or USB Camera Python libraries (OpenCV, NumPy, etc.) Example Python Code (simplified): python Copy code import cv2 # Initialize camera cap = cv2.VideoCapture(0) while True: ret, frame = cap.read() # Convert image to grayscale gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY) # Detect edges using Canny edge detector (basic example) edges = cv2.Canny(gray, 50, 150) # Display the result cv2.imshow('Edges', edges) # Break the loop on key press 'q' if cv2.waitKey(1) & 0xFF == ord('q'): break # Release resources cap.release() cv2.destroyAllWindows() This code captures video, converts it to grayscale, and applies edge detection. You can build on this to detect the grass cut line. With this approach, you can definitely make your robotic lawnmower more accurate and efficient in following cut paths. +++++++++ Good Luck and I wish you great success with your project!

nice project. I made a very similar pair of robots a couple of years ago. One cleaned floors, one just roamed around and talked. Good job, this really is incredibly similar (mine had ESP32 cores and roamable http management). Well done

you forgot to mention the back wheels have RGB! RGB == FAST!

Hi, I'm looking into making my own mower too. It seems that all Ublox NEO-6 GPS can do RTK roving. And the Ublox NEO-6P is needed for the base station, that seems to make GPS RTK at slow speed quite affordable. I'm waiting for my GPS modules in the mail to check if I can really do slow RTK for cheap.

Would a Lidar help to map the terrain? There is some pretty reasonable ones these days Andreas Spiess put one up th-cam.com/video/ddxguAzzzJE/w-d-xo.html

You need some AI and a chat bot to make it work effectively oh and blue tooth if you plan to market it! I am being facetious - well done!!

A lot of fresh ideas, awesome!

How cool. Might have to build one.

I like your work with ArduPilot I have a robotic tractor tractor I am making for small farms hear is a link to video I made a few years ago th-cam.com/video/pCdD5y2RGsc/w-d-xo.html just wondering how much you would charge to get ArduRover working on it. I really like you AI Solar Weeder I would love to see that on the FarmHand tractor.

I've seen quite a few robot mower videos... some DIY and some retail and I'm always left wondering why these things don't simply use a 40-volt weed-eater. Very safe and effective. a 2ah battery would run the cutter for 30 minutes. I envision a robot mower that you slot in 2x 6ah 40v batteries, and it can mow for 90-120 minutes, with very little risk to life.

wow I bought alot of the same parts glad to know im on the right path.

Capacitive touch to sense the grass?

very cool. now a radar sensor to map the yard out etc.

what about using two copper strips mounted parallel to the ground and when they come into contact with the grass you can measure the electrical resistance

Very cool. I don't think throttle control will help you much. You'd be better off using a relay and grounding out the magneto. That's usually how the kill switch on most mowers and 2 cycle engines work.

Fantastic!!! I want to build one of these.

My friend. Please turn on the translation...

Dude this is awesome. Now do a zero turn

Shimano tandem brake cable

Dope af update nice to see big yard treating u good! Peace unto u

I'd be happy without autonomy. Just putting a sprayer on an FPV drone and taking out weeds manually would be fun!

lithium ion batteries would work just fine lol

This is great! I had a similar idea, because I live ina a farm. Did you think about adding FPV?

duuuuuuude, way underrated channel. you're gonna be huge!

4:12 I don't know how much of a concern it actually is, but I've always heard to use stranded wire instead of solid in heavy vibration applications due to copper's ability to work harden and get brittle. Keep up the good work!

This is getting very cool. The thing you call a "mower body" is actually called the "deck" in the trade. You can buy them separately online. Also, you can search for entire parts diagrams and spare part numbers for most mowers. Also, just my opinion, not criticism of this cool project: I think you should reconsider implementing lithium for the traction control only, using a generator or maybe just a regulator that is more suited for lithium (search: hobby engine generators) your runtimes will stay long for a while more than using lead acid especially because this is probably abusing those packs. One day, I would love to try a zeroturn control platform using linear actuators to push the control arms forwards backwards, but that is so dangerous for so many more reasons. Your projects are cool, keep it up!

Quick & effective!

Sensacional o teu projeto... sou novato no arduino e estou bem interessado em montar um contado semelhante ao seu. Pena qua as informações ainda são bem restritas de como montar. Obrigado por compartilhar seus conhecimentos. Tmj! Forte abraço

Hmm i wonder how to hook controls up to a zero turn instead of having electric motors driving the machine 🤔
