VRoxy system pushes telepresence past simply wanting and speaking


When it comes proper right down to it, most telepresence robots are primarily simply remote-control tablets that may be steered round a room. The VRoxy system is totally different in that its robotic replicates the person’s actions, plus it auto-pilots itself to totally different places inside a given area.

The system is being developed by a staff of researchers from Cornell and Brown universities.

In its present practical prototype kind, the VRoxy robotic consists of a tubular plastic truss physique with motorized omnidirectional wheels on the underside and a video display on the high. Additionally on the high are a robotic pointer finger together with a Ricoh Theta V 360-degree digital camera.

The remotely positioned person merely wears a Quest Professional VR headset of their workplace, house or just about anyplace else. This differentiates VRoxy from many different gesture-replicating telepresence methods, wherein comparatively giant, advanced setups are required at each the person’s and viewer’s places.

By way of the headset, the person can swap between an immersive dwell view from the robotic’s 360-degree digital camera, or a pre-scanned 3D map view of all the area wherein the bot is positioned. As soon as they’ve chosen a vacation spot on that map, the robotic proceeds to autonomously make its means over (assuming it isn’t there already). When it arrives, the headset robotically switches again to the first-person view from the bot’s digital camera.

Not solely does this performance spare the person the effort of getting to manually “drive” the robotic from place to put, it additionally retains them from experiencing the vertigo which will include watching a dwell video feed from the bot whereas it is on the transfer.

The VR headset screens the person’s facial expressions and eye actions, and reproduces them in actual time on an avatar of the person, which is displayed on the robotic’s display. The headset additionally registers head actions, which the robotic mimics by panning or tilting the display accordingly through an articulated mount.

And when the person bodily factors their finger at one thing inside their headset view, the robotic’s pointer finger strikes to level in that very same route in the actual world. Down the highway, the researchers hope to equip the robotic with two user-controlled arms.

In a take a look at of the prevailing VRoxy system, the staff has already utilized it to navigate backwards and forwards down a hallway between a lab and an workplace, the place a person collaborated with totally different individuals on totally different duties.

The examine is being led by Cornell College’s Mose Sakashita, Hyunju Kim, Ruidong Zhang and François Guimbretière, together with Brown College’s Brandon Woodard. It’s described in a paper offered on the ACM Symposium on Consumer Interface Software program and Know-how in San Francisco.
