Hi, I tried running it on raspberry pi zero and getting this npm error that i can't find the way to fix. Is this on my side or that's smth else?

I didn't try this with the raspberry pi yet.

But you can try the following:

You can also try checking out what other people have tried when npm install fails with too many symbolic links

try npm run dev:client or npm run build:client

Getting npm ERR! code 127. Tried different your commands that you listed. Error127 will try npm install again,

mithi commented 3 years ago

i dont know why react scripts was not installed when you ran npm install. (it’s listed in the dependencies)

try installing react scripts first with

npm install react-scripts

Capture After fixing npm issues managed to start building it with small exception had to create a .env file in the root directory of the project and add this line SKIP_PREFLIGHT_CHECK=true inside the file. But ran into another issue. I'm using raspberry pi zero and by the looks it is struggling because of lack of RAM? But at the same time if you managed to run it on way slower computer I'm thinking there should be a work around.

mithi commented 3 years ago

Hi Zeke,

If the Raspberry Pi Zero is struggling, and you're planning to open the browser app on a different computer anyway, you can try the following instead...

On the faster computer where you plan to open the browser app do npm install && npm prod:client

Then on the Raspberry Pi Zero run ``` $ npm install express johnny-five socket.io http://socket.io $ npm run run:server ``` since those are the only three packages required to run the server needs, if i'm not mistaken.

Don't forget to edit ***SOCKET_SERVER_URL and **SOCKET_CLIENT_URLS* of the file https://github.com/mithi/hexapod-irl/blob/dev/src/_VAR_CONFIG.js appropriately.

If you insist on running the client app on the Raspberry Pi Zero the following links might help you solve this! https://blog.asayer.io/javascript-heap-out-of-memory-error https://stackoverflow.com/questions/42730801/how-do-i-tune-node-js-memory-usage-for-raspberry-pi

Hope that helps!

ok I'm trying to run the server on my PC. I did all npm installs and got it running but when I do npm run run:server on pi it can't find device. pi@raspberrypi:~/Desktop/hexapod-irl $ npm run run:server

hexapod@0.1.0 run:server node ./src/_ROBOT_SERVER.js

listening on *:4001 1610928992791 Board Looking for connected device
1610928998554 Board No connected device found

In VAR_CONFIG.js on raspberry pi I changed SOCKET_SERVER_URL with the url I got when i ran a server on my PC and updated SOCKET_CLIENT_URLS or I'm missing something else?

mithi commented 3 years ago

do you mean you are running the server on your your raspberry pi (ie you ran npm run run:server) and the react app (ie you ran npm prod:client on your pc? do you have an arduino connected to your raspberry pi?

mithi commented 3 years ago

if the board is still not being detected

try specifying the actual port, check out the example here of how to specify port http://johnny-five.io/api/boards/

check how you can get the name of your port https://www.raspberrypi.org/forums/viewtopic.php?t=217209

try making an led work first by following the instructions here: http://johnny-five.io/examples/raspi-io/

once you manage to get the above script work

edit src/_ROBOT_SERVER.js remove line 23 and after line 4, add

let Raspi = require("raspi-io").RaspiIO; let board = Board({ io: new Raspi() });

hope that helps

Well, I thought that I could get away only using raspberry pie and my personal PC to control it. On my PC ran npm install && npm prod:client and on raspberry pi npm run run:server. I also modified VAR_CONFIG.js on RP. You ask if I have an arduino connected to RP well no I'm only using RP. Is that even possible :D. I'm studying computer design and had a 3d modeling project where i decided to make a hexapod I have bare minimum in programming or robotics :(

mithi commented 3 years ago

okay, what are you going to use to drive the servos? are you using pca9685?

2xPCA9685 0x40 and other is 0x41

2xPCA9685 0x40 and other is 0x41

I haven't tried it myself, but technically it should be possible (as discussed here: https://github.com/rwaldron/johnny-five/issues/1560 ) by using this repository: https://github.com/nebrius/raspi-io

Zeke420 commented 3 years ago

Would it be better to adopt a hexy code to a custom shell than trying this one?

mithi commented 3 years ago

You could try that, but be aware that repo is no longer maintained (it's archived)

or you could try to make it work with https://github.com/nebrius/raspi-io | rwaldron/johnny-five#1560

Another alternative is to buy a cheap arduino chinese clone which is usually priced around 5 - 10 usd.

Zeke420 commented 3 years ago

I also have a AT mega328 UNO will this work? I can't find it on Johnny-Five supported board list Well I connected PCA9685 to it and uploaded StandardFirmataPlus to Arduino and getting this error. Arduino connected to COM4. It seems like it is trying COM1 at first and fails and does not proceed to the next one. Capture

It's literally the first board in this list http://johnny-five.io/platform-support/#arduino-uno

Well I connected PCA9685 to it and uploaded StandardFirmataPlus to Arduino and getting this error. Arduino connected to COM4. It seems like it is trying COM1 at first and fails and does not proceed to the next one.

Example of how to specify the ports http://johnny-five.io/examples/board-with-port/ Also there is a message on your screenshot that says See: https://github.com/rwaldron/johnny-five/wiki/Getting-Started#troubleshooting

Zeke420 commented 3 years ago

Hexapod will only move to its starting position when I start(npm run run:server) and won't respond to anything after that(changing angle in the web app). I'm not getting any errors.

Make sure your urls https://github.com/mithi/hexapod-irl/blob/dev/src/_VAR_CONFIG.js on BOTH your PC and raspberry pi are correct

If you're not getting lag: {SOME NUMBER} like here https://github.com/mithi/hexapod-irl/blob/bb44eaf1a79e567a8bc193d5a12ccbeaf7c91042/src/_ROBOT_SERVER.js#L74-L75

Then your server is not communicating with your client

Note: I will be closing this issue, since this is not an npm error anymore
