benbusby / piro Goto Github PK

Hello and thanks for the neat project!

In the Readme you write something about a test_motors.sh in the utils folder, as of now there is no test_motors.sh in the utils folder

I'm running raztot under a different user account (root instead of pi) and when I try to enable the video stream it fails.

I know I shouldn't be running it as root, but if I used a different user (e.g. ewegene) this problem still would have surfaced.

Hi,

Followed your tutorial but when I connect to my RazTot via Dataplicity I only see around 1-2 seconds of video before the feed dies and I see the following getting spammed in my terminal (on my pi):

[ERR] [ice.c:janus_ice_outgoing_traffic_handle:4118] [5714788999919634] ... only sent -1 bytes?

Any idea of what would cause it to work for a split second and then just stop suddenly? If I watch my "wormhole" page even after the video cuts out I can see the steamrate going up and down, but no video. I tried it in Chrome and Safari on my Mac and both times I see that above error on the pi almost immediately.

Thanks!

I have an issue running the raztot app after succesful install. I get stuck here, and Janus reports errors, I hope someone can spot my mistake, i'm quite new to linux:

I followed and sat up everything according to the guide, but it does not seem that i can open the Raztot webapp even though my Dataplicity server link is working fine. I have also tried to run the app locally, but with same result. Hopefully it's ok to ask this here, also new to github :)

Hello again! Here are a few things I found:

• In setup.sh under "Generate self-signed certificates" you generate certificates and try to copy them to the /etc/nginx/ path before installing nginx (so this will fail)
• You seem to install a large amount of unneeded packages. Over 200 packages including the x-server for some reason
• In the nginx part of the setup.sh you copy the nginx config to sites-available but never link this file to sites-enabled which means the file will never be used. You could install it directly to sites-enabled which is not best pactice but gets the job done for this project
• The nginx config includes the link to the certificate files but it will never use them because you specified that the server will only listen on port 80 so all https requests will result in "connection refused" errors. adding "listen 443 ssl;" will fix that

Will it be possible to have a third servo controlled through the app? I want to have a servo activating a laserpointer while you press the up key on the keyboard in the webapp, so it will activate while the RazTot is moving forward. It is working now on GPIO pin 17, and running on the 3v output, but I wanted to be able to run it simultaneously with the wheels.

So my question is: What do I have to change in the code to run GPIO pin 27 as if it was 22 and 17, but all at the same time? I will look through the code and see if I can figure it out, but if you have time to help a coding noob it would be awesome :)

When starting raztot it has the following prompt:

Run Janus Gateway? (y/n)

When choosing n it will still run and allow you to log in, but video streams don't work.

The captures output directory doesn't exist by default. When trying to create a recording it fails:

Additionally, when trying to view a list of the recordings it also fails:

You are not using a H bridge.. a motor driver. Won't you burn the raspberry pi ?
How did you solve this ?

Thank you so much for this wonderful app! I actually bought my first pi just to install and play with raztot.

The installation went smoothly, the ./test_motors.sh 17 22 works as expected, the wheels turn, I can start the stream, capture images and video and play them back but nothing happens when I press the arrow keys on the keyboard. This is true for both source run.sh local and remote. I also checked out the feature/mobile-controls branch but also here nothing happens when i swipe on my iphone. Another thing I noticed is that no stats appear in the right hand corner it says:

Camera Status: Offline
Recordings: N/A
Stream Status: Live
Temperature: ???
Stream Rate: 3099 kbits/sec
Storage: ??? / ??? GB remaining
Version: 1.0.0

I would really appreciate your support on how to debug this issue further to get it up and running.

Thanks in advance.

Me and my kid had a great time with raztot so far, thank you again for that! We checked out your mobile-controls branch and while it works, it feels buggy as the commands (i.e. touchend) don't seem to be transmitted directly and the robot keeps on driving after the touch is ended. While searching for a smoother solution I stumbled accross the following repo: https://github.com/ufulu/robotcontrol-javascript and wanted to know your thoughts if this could and should be integrated? While I have been tinkering around with python, flask and JavaScript for a bit in other mini projects I am not quite sure how to incorporate these controls on my own.. :/

Need to reevaluate which packages are necessary and removed any that aren't needed.

All working browsers now require SSL encryption for WebRTC. This basically means iOS will not work with this unless you go through a very convoluted process of creating a CA cerificate, then a self signed cert using that CA and then installing that CA in iOS. Android is less an issue since you can just bypass the warning, but you can't go full screen if the SSL cert has an error so if you want full screen video on a phone/tablet you are stuck with the same workaround needed for iOS to work at all.

Note I've built effectively this same app and am looking for an alternative workaround. Eg low latency streaming to a browser. WebRTC is just not going to do it.
