VRPN, which stands for Virtual Reality Peripheral Network, is like a big toy box that helps video game makers and other people who make virtual reality things, like robots, get all their toys to work together.
You know how when you play with your toy cars, you have to use different remote controls to make them move? That's kind of like how video game makers and other virtual reality people used to have to control all their toys separately. It was really hard and time-consuming!
But with VRPN, they can make all their toys work together with just one remote control. It's like magic!
So now, video game makers can make their VR games and robots work seamlessly together without having to worry about all the different controls. VRPN makes it so much easier and fun to play with virtual reality toys!
