Interesting Libraries for WebRTC.

Session Traversal Utilities for NAT (STUN)  https://www.rfc-editor.org/rfc/rfc8489.html

Traversal Using Relays around NAT (TURN)  https://www.rfc-editor.org/rfc/rfc8656.html

Interactive Connectivity Establishment (ICE)   https://www.rfc-editor.org/rfc/rfc8445.html

coturn is a free open source implementation of TURN and STUN Server.

 The TURN Server is a VoIP media traffic NAT traversal server and gateway.

Violet - Lightweight STUN/TURN server

Violet is a lightweight STUN/TURN server (RFC8489 and RFC8656) written in C without dependencies, based on libjuice.

libjuice - UDP Interactive Connectivity Establishment
libjuice   (JUICE is a UDP Interactive Connectivity Establishment library) allows to open bidirectionnal User Datagram Protocol (UDP) streams with Network Address Translator (NAT) traversal.

The library is a simplified implementation of the Interactive Connectivity Establishment (ICE) protocol, client-side and server-side, written in C without dependencies for POSIX platforms (including GNU/Linux, Android, Apple macOS and iOS) and Microsoft Windows. The client supports only a single component over UDP per session in a standard single-gateway network topology, as this should be sufficient for the majority of use cases nowadays.

libdatachannel - C/C++ WebRTC network library
libdatachannel is a standalone implementation of WebRTC Data Channels, WebRTC Media Transport, and WebSockets in C++17 with C bindings for POSIX platforms (including GNU/Linux, Android, FreeBSD, Apple macOS and iOS) and Microsoft Windows. WebRTC is a W3C and IETF standard enabling real-time peer-to-peer data and media exchange between two devices.

Fwd: [HBRobotics] Telepresence robots for social interaction

---------- Forwarded message ---------
From: Dheera Venkatraman

Hi everyone,
Among the many uses for robots during this pandemic, I think one of
the hugely overlooked use cases is in keeping up mental health of the
community by facilitating human-to-human social interaction. I'm
building a small fleet of mini budget telepresence robots and they're
working pretty well in connecting friends!

They use a Pixel 1 phone for compute (which can be had for <$65
second-hand on eBay) and everything runs from within a HTML5 webpage.
2-way audio/video stream is over WebRTC. Tele-operation is done over
socket.io and the phone communicates to motors via bluetooth to an
ESP32 and a DRV8833.
