When it comes proper all the way 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 areas inside a given area.
The system is being developed by a crew of researchers from Cornell and Brown universities.
In its present useful prototype kind, the VRoxy robotic consists of a tubular plastic truss physique with motorized omnidirectional wheels on the underside and a video display screen 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 programs, through which comparatively giant, advanced setups are required at each the person’s and viewer’s areas.
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 the complete area through which the bot is positioned. As soon as they’ve chosen a vacation spot on that map, the robotic proceeds to autonomously make its approach over (assuming it is not there already). When it arrives, the headset mechanically 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 screen. The headset additionally registers head actions, which the robotic mimics by panning or tilting the display screen accordingly by way of 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 check of the prevailing VRoxy system, the crew has already utilized it to navigate forwards and backwards down a hallway between a lab and an workplace, the place a person collaborated with totally different folks on totally different duties.
The research 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 introduced on the ACM Symposium on Person Interface Software program and Expertise in San Francisco.
