IMHO those two wheel balancing robots are sign of sophisticated control enough. There is this rotation sensor but might be hard to find: https://www.brickeconomy.com/set/9756-1/lego-mindstorms-rotation-sensor

This Im trying to find out so I can search for suitable Lego sets on offer. I just bought (not received yet) a second hand 42160 Audi RS Q e-tron which has the "technic hub" and 3 motors to get started (if they work).

I think/hope this too.

Thanks for the clarifications Lok24. What I mean by "Pybricks works" is that they list the compatible parts on their website. Though i would like to see the exact part numbers, since there are several parts that look exactly the same but I have no idea if they will work. For example Technic / medium hub: 88012, 22127, 85824 Spike Small Angular motor: 68488, 45607 Pu XL motor: 88014, 22172 Color Sensor: 37308, 45605 Distance Sensor: 37316, 45604 Force Sensor; 37312, 45606 Is there any info on those, are they the same parts and thus compatible with Pybricks?

Thanks, this is great resource for selecting parts.

Lego says The Control+ and Powered Up components aren’t designed to be compatible with the SPIKE Essential or SPIKE Prime hub, which means they won’t be detected by the SPIKE app. https://www.lego.com/en-us/service/help/LEGO_Education/spike-essential-with-other-robotics-systems-kA009000001KVc8CAG And: The new hub and the motors also belong to the Powered Up family, so they share the same port and protocol like the Powered Up, the Boost and the Spike Prime sets. https://racingbrick.com/2019/08/control-plus-aka-powered-up-new-hub-and-motors-clarification/ So physical ports and protocols are compatible but Lego apps will have issues while pybricks will work (as you said). I'm not going to mix hubs, but will buy sets on sale which have various motors and sensors, so they should work with any of the better new hubs. Probably getting Spike if find it for a good price.

So I have studied the parts a bit and there seems to be at least 5 (!) different ecosystems: Mindstorms EV3 / NXT Wedo 2.0 Powered Up Control+ Spike Is it really so that these are not compatible? Lego support says for example that Spike hub does not connect to powered up devices. So if you would like to buy sets for Spike system, you are out of luck. This is grazy...

Nice stuff!

Okay you have the same result as ramblingbrick.com.

Could there be different versions of 42176? I was reading it here: https://ramblingbrick.com/2024/07/28/42176-porsche/

Is Technic Move Hub programmable as powered up system, or is it limited to control+ app? 42176 - Porsche GT4 e-Performance would be on offer here now. These are a bit confusing have to say...

Thanks, lots of interesting stuff there but mostly wheel based though. Maybe I can be clever and use a control/camera system that works with both ;) Then start with Legos and move to other stuff if they won't work anymore.

I don't know exactly, but some kind of (indoor) moving things that act and react with environment. There are some nice ready made AI models (for example https://huggingface.co/openvla/openvla-7b) to try out. So no end goal but have fun experimenting with what is possible and with fairly low budget.

Thanks for the links! Legos came to mind as the first options becaouse they are familiar. I'm interested in all options, so are there other methods that don't require manufacturing or 3D printing parts?

Learning a lot here, thanks! M5 STACK ATOM looks really nice - small and light package.

Yeah I don't know about Spike, just you didn't mention it so guessed. I would rather avoid bying an expensive Lego kit. Arduino or ESP seems a good way to go if they are compatible and come without Lego price tag :)

>> I would to today not recommend a Pi, nor Buwizz, nor EV3, nor NXT. So Spike would be okay? Powered Up Hub does seem a bit hassle with the batteries. M5Stack is a new world for me so have to study those and your examples too.

Thank you for all the tips. So for the controller there are 4 options: Spike, EV3, Buwizz and Pi+hat and each could be bought separately without a Lego kit. And then all motors, actuators and sensors (Lego and 3rd party) can be bought separately also, which I didn't think of. Out of controllers, Spike seems to be the smallest, but is it possible to utilize external services (vision, control) with that? With PI+hat almost anything would be possible, but it's a bit bigger and needs an additional battery. Then there is the question: are all the systems compatible, or do you have to select one based on what kind of components you want to add?

Hi, i have been building with Legos as child in 80's and 90's, mostly technics. Favourite set was of course this https://brickset.com/sets/8860-1/Car-Chassis. Now I'm developing LLM (AI) server applications (customized chat bots etc) for a living and got an itch to start playing with robotics for a hobby. It seems that Spike Prime is the only available Lego kit nowadays? It supports python so I guess you can program any logic that you like with it? And you can add OpenMV for basic computer vision. Ideally I would like to have Raspberry PI or more powerful edge computing system for advanced vision and control. Even a wireless connection to Linux server would be nice. Where could i find more info on how to get started? Does anyone here have builds to show?
