@@AvivMakesRobots So far I have seen people stream video over lora. It would be nice to have a 3D printable enclosure that can attach to say a ball cap that can stream the video over lora using a micro controller and take various common lcd type screen sizes like 1.44 or larger that will adjust for how close it is to eyes. I have been looking for that kind of a springboard to start further development for myself as I have a different type of job altogether but could help. If that is something your interested in let me know and I can send you some youtube videos that I have. I feel like people are chomping at the bit for something like this.

Love the project, and I'm really enjoying the videos, especially your idea to use a drawer slide for raising the camera. Did you encounter any video signal (timing) issues by introducing cable length (and therefore a propogation delay) between the camera & the RPi? Do you have any future plans to provide a "kit" of the 3D printed parts? I don’t have a 3D printer, so that's a stumbling block for me.
@AvivMakesRobots Жыл бұрын
Hi! I did not encounter any issues, possibly because the cable length came stock with the camera and is using USB 3.0. I absolutely want to create kits for this, I am just deciding if printing the parts myself or having them made elsewhere makes sense. If I was printing them myself and hit a snag, it could cause major delays. My future videos will touch on this topic. Stay tuned!

This is in my view, an engineering Failure of a "Military Robot" Those cells are gonna pop out as soon as you drop down even 20cm, you're using *brushed* DC motors to drive the sprockets, the camera on the front alongside its lights is *completely* exposed to the elements and anything you run into, and god forbid this thing ever turns on its back because if that happens with any force, that antenna is quick to break off. And all of that is not even mentioning the reliability issues you're gonna get from any sand or fluid coming through the improperly sealed chasis or other moving parts. The fact that you just laid the "camo" on top of the tracks really shows it best how little of an idea you have there in terms of longevity. That fabric isn't gonna last you more than a week when driving on any amount of rough sand or gravel, without tearing off. And lastly, those exposed track sides can easily get stuff stuck in there like twigs, leaves, branches, you name it.

With the amount of dust and sand building up on that lens it won’t be long before it is damaged. Also the video won’t be very useful if it is covered in sand. There is a reason most robots have the camera up away from the ground. Also the night vision mode may work better higher up as well, at the moment you are essentially trying to illuminate and view a plane in a bad orientation for the camera and IR lights. Having less of an angle between the ground and the camera would allow it to be illuminated better which should make the camera pick it up better too.

One question: I skipped through some parts of the video so I am not sure where the front is. Is it on the side with the camera? In the video it was shown driving in both directions. If the front is on the side with the camera I would mount the suspension facing in the other direction because this type of suspension works better in one way than the other. (But I am not sure if this is a big deal on such a small scale) I would also consider a stabilizer for the camera because it is shaking quite a bit and I would mount the camera in an elevated position instead of inside the hull for 360° vision.

@TonyGrant.2 жыл бұрын
@@AvivMakesRobots I'm glad that you agree! I hope you don't mind if I elaborate... Part of the issue is that with the camera and illumination close to the ground there is a very bright patch on the ground close to the camera which the camera is auto exposing for which causes the darker background to be underexposed. With the IR lamps close to the ground the light intensity falls off fairly sharply so it is comparatively dark not far from the tank but the camera is setting it's exposure for the very bright light on the ground close to the tank - it's probably overpowering the auto exposure system. If the source of illumination and the camera are up higher the light won't be as bright right in front and the intensity of light will fall off more gradually which hopefully the camera will be able to cope with better. Also, because with the camera up higher the bright patch (which will be less intense with the IR mounter higher) will be smaller on the image/exposure sensor having less impact on the auto exposure of the camera. So the solution might be just to improve the lighting by changing the angle of illumination rather than getting a more sensitive camera or brighter IR lamps. I hope this helps.

The angle of the LED bulb itself would be angled, calculated to hit the ground at that distance away based on whatever beam angle it is.

@@AvivMakesRobots I'm glad you found my comments helpful. I should point out that I'm speaking from my lighting experience as a photographer, not any experience specifically related to your application. I have spent a lot of time working with, setting up and observing lighting/light for many years. Also, you are lighting for a camera, so I think my experience does have some relevance here. But there may be others here who have more experience specifically related to what you are doing. Just to be clear; by "beam angle" do you mean the angle of coverage that the beam emits? I am answering your question in that context. As long as the beam is not too narrow/concentrated I don't think the beam is as important as how it is mounted because that will affect how the camera reacts and what you see. Having both the camera and the lights elevate should help, as I suggested before. But if you think your beam is too narrow I'd definitely consider a wider one. But you will still get a hot spot near to the vehicle if it is not mounted high enough. However, there are three tests that I can think of that you can do before you decide on new LEDs: 1) Temporarily mount the LEDs above the camera and possibly even back away from the front of the vehicle. 2) With the LEDs mounted higher, place a diffuser of some sort in front of the LEDs. This will scatter the beam giving a wider angle of illumination. Some possible diffusers are: A piece of tissue paper mounted on a small frame - I bet you could print a nice little frame for one, a small lens, crinkled cellophane. 3) Add to that a small screen/baffle, in front of, and below the LEDs to shade the area immediately in front of the vehicle. Adjust it to different positions to see if there is a sweet spot. Test each change sequentially. You could go straight to step 2 & 3 with the lights in their current position but it might not work. I suspect that the light source has to be further away from the camera so the mods don't interfere with the camera's exposure or create flare. Leaving the camera where it is will be OK. These changes should give you an idea of whether my original suggestions would help. Then you can consider any design and equipment changes.

Great project, however there are a few things you might want to adjust. I see that you're using L298N drivers, which are pretty easy to use, but are pretty limited in the power they can handle, with something like 1.5A max and can turn very hot. Specially in a 3D printed vehicle that can become an issue. You might want to concider some other drivers, or (and that would be my suggestion) go with 2 ESC's and RC control. That'll give you the option to use larger motors such as a 540 or even 775 with low RPMs, but also you can use LiPo's without having to worry about overdischarging them, and is a lot more universal. Controlling the droid by WiFi is nice, however is pretty limited and you need to concider how to handle loss of signal etc. A way more easier method would be to use RC transmitter and receiver. It's easy enough to capture the receivers output with an arduino, then you can modify your signal as pleased for either driving or other functions such as lights, and then send the output signal to ESC's or whatever you want to control. As upgrade you might want to look at adding GPS. A Neo 6M module would do perfectly fine for these kind of jobs. You can then either store the location in a timeline db such as flux, either on the Pi or sent it directly ove WiFi to a database. Another suggestion would be to add sensors for autonomous driving, with an ultrasonor sensor such as an HC-SR04 and / or use a lidar such as a TFmini. There's a lot of documentation on this subject.

Hey, I uploaded a video today on how I want to make a PCB for this. I am still using WiFi because it is easy to connect to using your cell-phone. It is also easy to connect other stuff like lidar and just program it in. With an RC transmitter, it might be more complicated. All good suggestions. I am switching to a Cytron 10 amp, 2 motor chip for the motors. I am planning on having GPS right on the chip.

Great build and video, especially all the editing and explanation. As far as sensors, I would consider using a depth camera (like the orbbec astra embedded s for example) You would get the image stream and also a depth stream that could be used for mapping the terrain ahead in detail so it could pick a path around obstacles. The depth part works in total darkness, but the imaging part would only work in the light.
