A humanoid robot can relay video and touch sensations to a person wearing haptic feedback gloves and a VR headset hundreds of kilometres away, offering a way for people to attend events without travelling. The iCub 3 robot is a 52-kilogram, 125- centimetre-tall robot with 54 points of articulation across its aluminium alloy and plastic body. Its head contains two cameras where a human’s eyes would be, and an internet-connected computer where the brain would go. Along with the cameras, sensors covering its body send data to the robot’s brain. These sensations are then replicated on a suit and VR headset worn by a remote human operator.
When the operator reacts to what they see and feel, the suit’s sensors pick up the movements and the robot match them. The key is to translate every signal and bit of numeric data that can be sent through the network. There can be a small delay of up to 100 milliseconds to capture and transmit the visual footage, but the operator can mitigate this by moving slightly slower than normal. The team has demonstrated the robot at the Venice Biennale, where it wandered through an exhibition while its operator stood 290 kilometres away in Genoa. People could use the iCub 3 to attend events remotely, reducing the need to travel.
