With lockdown regulations sweeping the globe, many have found themselves spending altogether too much time inside with not a lot to do. [Peter Hall] is one such individual, with a penchant for flying quadcopters. With the great outdoors all but denied, he instead endeavoured to find a way to make flying inside a more exciting experience. We’d say he’s succeeded.
The setup involves using a SteamVR virtual reality tracker to monitor the position of a quadcopter inside a room. This data is then passed back to the quadcopter at a high rate, giving the autopilot fast, accurate data upon which to execute manoeuvres. PyOpenVR is used to do the motion tracking, and in combination with MAVProxy, sends the information over MAVLink back to the copter’s ArduPilot.
While such a setup could be used to simply stop the copter crashing into things, [Peter] doesn’t like to do things by half measures. Instead, he took full advantage of the capabilities of the system, enabling the copter to fly aggressively in an incredibly small space.
It’s an impressive setup, and one that we’re sure could have further applications for those exploring the use of drones indoors. We’ve seen MAVLink used for nefarious purposes, too. Video after the break.

CES 2017 is over and there were VR gadgets and announcements aplenty, but here’s an item that’s worth an extra mention because it reflects a positive direction we can’t wait to see more of. HTC announced the Vive Tracker, to be released within the next few months.
The Tracker looks a bit like a cross between a hockey puck and a crown. It is a self-contained, VR trackable device with a hardware port and built-in power supply. It can be used on its own or attached to any physical object to make that object trackable and interactive in VR. No need to roll your own hardware to interface with the Vive’s Lighthouse tracking system.
Valve have been remarkably open about the technical aspects of their hardware and tracking system, and have stated they want to help people develop their own projects using the system. We’ve seen very frank and open communication on the finer points of what it took to make the Lighthouse system work. Efforts at reverse-engineering the protocol used by the controller even got friendly advice. For all the companies making headway into VR, Valve continues to be an interesting one from a hacking perspective.

[Florian] has been putting a lot of work into VR controllers that can be used without interfering with a regular mouse + keyboard combination, and his most recent work has opened the door to successfully emulating a Vive VR controller in Steam VR. He uses Arduino-based custom hardware on the hand, a Leap Motion controller, and fuses the data in software.
We’ve seen [Florian]’s work before in successfully combining a Leap Motion with additional hardware sensors. The idea is to compensate for the fact that the Leap Motion sensor is not very good at detecting some types of movement, such as tilting a fist towards or away from yourself — a movement similar to aiming a gun up or down. At the same time, an important goal is for any added hardware to leave fingers and hands free.
