Remote: Radiomaster Pocket ELRS with ELRS receiver
Chassis: Haven't done the chassis yet, in planning stage.
But the issue now is that I need to design the drivetrain system to buy the mechnical parts; like, pulleys, belt, bearings and the carden.
My first thought of the drivetrain was to use direct motor to wheel, but with some chatting with ChatGPT, it convinced me to use 2 motors and pulley/belt system.
ChatGPT idea is to use 3 pulleys, one 16t in the middle which is connected to the motor and two 48t connected to the wheels, but the problem now is how to do that ?
I aksed different AIs about this but they provided me with something that can't be done in real life, this one was done by Gemini:
I moved your topic to an appropriate forum category .
In the future, when creating a topic please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.
Do you know, "AI" will churn out infinite answers, without a microsecond of original thought? It finds all the projects according to your input, statistically analyzes them, then cobbles together a guess.
We know. It doesn't.
Use what you know. Evaluate. Test. Stop asking AI. It will never help unless you tell it what to do.
I know that, I've been discussing this topic with different AIs for weeks. I asked ChatGPT to generate me with blueprints or drawings but it provided me with things that aren't practical. Like these ones:
And it's obvious that can't be done in L25cm x W25cm x H10cm robot chassis.
The problem is that I don't want to order that parts ChatGPT recommeded me to get, and then discover that I should have paid more attention and focus before purchasing.
Here I asked ChatGPT to provide me only with the mechanical system from the motor to the main pulley along with the front/rear pulleys. And this is what I got
Not the exact mechanical system, because I haven't and not planning to buy like those gearboxes. But I want to follow the basic concept which is using only 2 motors.
Please describe what you believe is the basic concept! What part of the U-TUBE machine is the basic design? Begin be making a drawing of that basic design.
@wolfrose - Stop asking AI for anything. Those AI images are a terrible... especially the Penrose/Mobius belts that flip over and exit pulleys sideways... stop asking AI. It knows nothing and creates nothing but chaos.
In your own hand, draw the thing you want to make. The image in your Post #1 looks like a great start. Start with drawing a box. Add some wheels. Describe the purpose of the box (the image has a camera, a distance sensor, maybe some IR detector, et c.). Describe how you expect the wheels to move (four independent motors? two drive wheels and two non-drive, steering wheels, slow like a Mars Rover or rapid like an RC car? Will it be RC or autonomous?)
Something like this is on the market... so adding the microcontroller, power supply and code to drive it would be the next step. Then add the peripherals
Ah! Thank you. A universal joint to couple two shafts meeting at a slight angle. For the OP purpose a rubber u-joint would be best for slight angles. Best if built with no angular difference. A rubber coupling eliminates the speed changes/jerking as the simple u-joint rotates.
