2 роки томуAttention: This is a re-published video. During my Summer Break, I decided to re-publish interesting older videos
In this first episode I show how I build my self-balancing robot based on an Arduino pro mini compatible MultiWii board. It consists of 3D printed parts and uses stepper motors. In the next episodes, I will continue and extend it with a remote control based on NRF24L01 chips and ultrasonic sensors to enable autonomous driving.

seeing your printout taped together reminded me I have an old daisywheel printer in my storage unit, I am going to retrieve it and see if I can get it working with a parallel emulator, those old printers were so cool!
@AndreasSpiess 2 роки тому
Indeed, back then we had piles of paper to debug our programs. Screens were not so big back then. But still today, if I want to get an overview, I sometimes stick the papers together...

great video and well explained as always!!! i wonder if is possible to add two movable sticks to help it climb stairs and so.... more processor, huh?

I saw such a design and tried it without success. It needs strong motors and a good traction on the floor.

Hi Andreas, That's a nice challenging and multidisciplinary project. One learns a whole lot of things when building one of those robots. I enjoyed the video. Kind regards, South Africa
@AndreasSpiess 2 роки тому
Indeed it created a lot of problems which had to be solved. This is why it is probably not a beginners project. But for an ambitious Maker this is a cool challenge.

I was just thinking around just such a project but with Reinforcement Learning as controller instead of a PID
@stal1963 2 роки тому
Reinforcement Learning makes a lot of sense for this kind of project, as it introduces more independence from the parts used. Will you document your experiences somewhere?
@shirishhirekodi6913 2 роки тому
@@stal1963 One of the first examples in RL is exactly this project. Called CartPole. It’s usually run in a simulated environment. My thinking was to implement the same in the real world. Sure will be documenting this when I get around to doing this. Now to get my hands on a 3D printer…
@AndreasSpiess 2 роки тому
Interesting idea. The setup of a "learning environment" in reality is probably not easy because the robot falls down a lot of times and it can get boring to restart it manually.
@stal1963 2 роки тому
@@AndreasSpiess That is true. The RL environment would need to store its state persistently and assign a big penalty whenever the robot falls. It could be interesting to build a self-balancing robot using a Jetson Nano.
@shirishhirekodi6913 2 роки тому
@@AndreasSpiess That's the wonder. The RL system will not be limited to the totally deterministic nature of PID, but will learn the rules dynamically on its own. It could potentially figure of some weird ways to avoid falling which you may have never considered. To see that, would be pure joy

@AndreasSpiess 2 роки тому
I assume a LoRa remote control could easily be done (just replace the NRF2401). Unfortunately, most "professional" weather stations use plain 433MHz and not the LoRa protocol. You would have to build your own controller and replace the one provided by the supplier.

But of course it is good for a school project or for demonstrations (when people are excited about it and know nothing about electronics) because for me it is like going to the gym and instead of lifting weights letting a machine doing it but there is a problem my muscles don't work. I see this like this but with brain.
@AndreasSpiess 2 роки тому
Try it and you will see how much problems you have to solve. Just start without my sketch... And even if you start with the sketch you will have to solve plenty of problems. Your "muscles" will be used, I am quite sure.
@radry100 2 роки тому
Is it possible to do without stepper motors but with normal motors? Quadcopters don't use steppers either.
@AndreasSpiess 2 роки тому
Yes, you can do it also with normal motors. They have to be quite slow (geared)
@grzesiek1x 2 роки тому
Which I don't like in projects like that is using all those prepared and fabricated and ready to use circuits ! I would prefer to know for exampe how transmitter /receiver work, what frequency , how to build it, why crystal oscyllator, how to filter desired frequency, how to demodulate frequency change (just examples), why this why that , many questions!! But like on the video I can build a whole robot without even knowing anything which is not good :/ I have been trying to do something similar with a drone and it is much more complicated when we build everything from scratch! Even adjust the response from changing the voltage from the accelometer is a challenge and not using Arduino (by using the op-amps for example) and make all this work...
@AndreasSpiess 2 роки тому
It all depends on your goals. If you want to learn about PID controllers and remote controls and create a cool gadget, this project is perfect. If you are interested in Wireless communication you find other videos on this channel explaining many things. And if you want to learn about RF you have to search for other channels. I do not cover those details, because not a lot of my viewers are interested in this detail. If you are interested in RF and communication theory I suggest that you learn for an Amateur Radio license. Then you are allowed to do your own experiments without being illegal. Otherwise building your own transmitter is illegal in most countries.
@grzesiek1x 2 роки тому
Thank you for the idea! I think it would be a good start with the licence etc. Any way I learn from the books and all chanells on youtuve I treat as something extra for better understanding or just to see how other people do things or ideas etc.
@grzesiek1x 2 роки тому
@@AndreasSpiess my goal is to learn as much as I can and be able (of course in the future) to build and develop my own circuits but I am not a "gadget guy" I mean I don't want to be just an user of electronics but build my own things and develop my own projects ! because from jsut using electronics i do have nothing but to know how to build things it is a different story. I know this is not very popular goal these days where everybody is for fun and gadgets but I like more the old school of creating things instead of just using.. But of course this project is very cool but I see the things from a little bit different perspectiv , more serious and maybe a new job one day etc.
@grzesiek1x 2 роки тому
@@AndreasSpiess btw I live in France (I am not french) and need to read al lthe regulations here but there was just an example ! I meant also other things like experiments with op-amps and analog sygnal accelerometers (and how to match the change of the voltage with current state of the robot and working motors et.c etc.) and for exampe logic gates, transistors , mosfets, relays to control motors and other things
@rfrisbee1 2 роки тому
The funny thing is once you know all the detail you will realise that to achieve anything significant with modern technology in a reasonable timeframe you have to use higher-level tools / intellectual property rather than develop everything yourself. Learning the details is interesting and fun though. Good luck on your journey!

I'm particularly interested in your 3D printer. It looks like one of those Chinese Makerbot Replicator 2x copies. Does it run well? I have a real one and converted it so a single nozzle printer with a removable heated bed and auto bed leveling. So far it's the best mechanical platform I've used. Curious to hear what kind of changes you made to your machine.

The „driving back to position“ behavior when you nudge it, is that the autonomous part or does the upright logic keep track of balancing movement and drives backs?
@AndreasSpiess 2 роки тому
It has no position awareness. So it only by chance goes back to where it was. The "keep me upright" does whatever is needed.
