During this Covid time, I am trying to make a telepresence robot for a few people close to me. Can I please get some info on what kind of protocols are available for the robot control over internet. I have tried googling around and what I found are
- Most of the tutorials are local network only, that is the controller and the robot are connected to the same network. I need to control the robot from literally halfway around the world
- MQTT, but my understanding is that it is clunky and laggy because it is more of a on/off style control instead of a continuous control
- Opening both controller and recipient router manually. Seems very complicated for the average user as well as possible security risks by misconfiguration
- Some other proprietary commercial grade protocols which are expensive, though my calculation of data usage might be wrong thus resulting in expensive estimate. I don’t mind paying if that what it takes but free is always good!
Thanks for reading, please CMIIW and hopefully someone can help!
