This is fantastic. Although I'm currently unable to watch the videos, I'm hoping that the people controlling the robots have various forms of feedback so that the interactions can give them some much needed human contact.
If they do open a permanent cafe of this type I'll be sure to visit next time I'm in the area.
They appear to have a video monitor with a camera feed from the robot, but I can’t figure out how they actually control the robot and how responsive it is.
The example i saw had a woman who had control of her eyes but nothing else. She had a computer monitor with eye tracking software installed. She could look at controls on the screen in order to command the robot. This was all overlayed on a live video feed from the robot. I'm assuming she also had sound since people were telling the robot verbally what their order was.
