Control a tracked robot with your mind (or joystick)

Whether you choose to control this vehicle with your mind or a joystick, the camera mounted on it will give you a new view of the world.

Maker “Imetomi” was inspired to create a tracked robot after he was able to salvage a camera off of a cheap drone. This became the basis of his FPV setup, which he fitted onto a little tracked vehicle. Although this would have been enough for most people, in addition to building a joystick-based controller, he also made it work with a brainwave headset.

Imetomi now has something that he can drive around virtually, spying on passersby, as long as it stays within the VR transmitter’s 50-meter range. Be sure to check out the video below, where the small bot shows of its impressive all-terrain capabilities, and read his Instructables write-up here.

 

Revealed: Homebrew Controller Working in Steam VR

[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.

[Florian]’s DIY VR hand controls emulate the HTC Vive controllers in Valve’s Steam VR Tracking with a software chain that works with his custom hardware. His DIY controller doesn’t need to be actively held because by design it grips the hand, leaving fingers free to do other tasks like typing or gesturing.

Last time we saw [Florian]’s work, development was still heavy and there wasn’t any source code shared, but there’s now a git repository for the project with everything you’d need to join the fun. He adds that “I see a lot of people with Wii nunchucks looking to do this. With a few edits to my FreePIE script, they should be easily be able to enable whatever buttons/orientation data they want.”

We have DIY hardware emulating Vive controllers in software, and we’ve seen interfacing to the Vive’s Lighthouse hardware with DIY electronics. There’s a lot of hacking around going on in this area, and it’s exciting to see what comes next.

Building a VR automatic camera tracker

Light graffiti, virtual reality, and motion control combine to make one amazing robotic sidekick.

Film making has advanced in a staggering way over the last 50 or even 10 years, but what if you were to augment your filming rig with a VR headset and add a camera that automatically tracks where a VR controller is? Jaymis Loveday did just this, and in the video below, you’ll see a very interesting result–he’s painting with light in thin air.

If you’ve ever tried light graffiti, you’re familiar with what he’s doing. The problem is figuring out what and where exactly you’ve painted, and his system seems to solve this.

Later in the video, he interacts with a virtual world while the real world is still in the shot, for a kind of mixed reality filming experience. The possibilities for this kind of interface are staggering, so hopefully we’ll see even more strange art in the future!

… it’s a project I’ve had in my mind since I first used the Vive over a year ago, at PAX Prime in Seattle. As soon as I waved the controller in front of my face and noticed the tracking speed and accuracy I started mentally designing camera tracking systems. I wanted a VR system in my life because I love games, but I needed a Vive for filmmaking science experiments.

You can see more about this rig on his website here or on the project’s Reddit post. You can also check out Loveday’s previous video tracking only version here.

The Oculus Cardboard Project: DIY Virtual Reality Gun with Tracking

I always wanted to shoot things in virtual reality but I'm broke so I did what I could. This is my attempt at an Oculus Rift style experience with Google Cardboard. This is actually a really fun project and its extremely easy to replicate. The parts cost around $15 total and will take about 45 minutes if you are new to Arduino.

Pong In Real Life, Mechanical Pong

[Daniel Perdomo] and two of his friends have been working on a mechanical version of Pong for the past two years. We can safely say that the final result is beautiful. It’s quite ethereal to watch the pixe–cube move back and forth on the surface.

[Daniel] has worked in computer graphics for advertising for more than 20 years. However, he notes that neither he nor his friends had any experience in mechanics or electronics when they began. Thankfully, the internet (and, presumably, sites like Hackaday) provided them with the information needed.

The pong paddles and and pixel (ball?) sit onto of a glass surface. The moving parts are constrained to the mechanics with magnets. Underneath is a construction not unlike an Etch A Sketch for moving the ball while the paddles are just on a rail with a belt. The whole assembly is made from V-groove extrusion.

Our favorite part of the build is the scroll wheel for moving the paddle back and forth. For a nice smooth movement with some mass behind it, what’s better than a hard-drive platter? They printed out an encoder wheel pattern and glued it to the surface. The electronics are all hand-made. The brains appear to be some of the larger Arduinos. The 8-bit segments, rainbow LEDs, etc were build using strips glued in place with what looks like copper foil tape connecting buses. This is definitely a labor of love.

It really must be seen to be understood. The movement is smooth, and our brains almost want to remove a dimension when watching it. As for the next steps? They are hoping to spin it up into an arcade machine business, and are looking for people with money and experience to help them take it from a one-off prototype to a product. Video after the break.

DIY Virtual Reality Skateboard

This is a really easy project that can be done in about an hour. It is more of a virtual reality experience rather than a game. An accelerometer/gyro goes onto an Arduino board and transmits the angular motion of the board via bluetooth to a (extremely amateur game) I made in Unity for Android phones. This only works for Android phones and your phone must be compatible with Google Cardboard.

‘Duinos and VR Environments

At the Atmel booth at Maker Faire, they were showing off a few very cool bits and baubles. We’ve got a post on the WiFi shield in the works, but the most impressive person at the booth was [Quin]. He has a company, he’s already shipping products, and he has a few projects already in the works. What were you doing at 13?

[Quin]‘s Qduino Mini is your basic Arduino compatible board with a LiPo charging circuit. There’s also a ‘fuel gauge’ of sorts for the battery. The project will be hitting Kickstarter sometime next month, and we’ll probably put that up in a links post.

Oh, [Quin] was also rocking some awesome kicks at the Faire. Atmel, I’m trying to give you money for these shoes, but you’re not taking it.

[Sophie] had a really cool installation at the faire, and notably something that was first featured on hackaday.io. Basically, it’s a virtually reality Segway, built with an Oculus, Leap Motion, a Wobbleboard, an Android that allows you to cruise on everyone’s favorite barely-cool balancing scooter through a virtual landscape.

This project was a collaboration between [Sophie], [Takafumi Ide], [Adelle Lin], and [Martha Hipley]. The virtual landscape was built in Unity, displayed on the Oculus, controlled with an accelerometer on a phone, and has input with a Leap Motion. There are destructible and interactable things in the environment that can be pushed around with the Leap Motion, and with the helmet-mounted fans, you can feel the wind in your hair as you cruise over the landscape on your hovering Segway-like vehicle. This is really one of the best VR projects we’ve ever seen.

Gravity Touch bluetooth Glove powered by Arduino Micro

Arduino user Jubeso submitted to our blog an instructable explaining the 10 steps to build an input device for gaming.

The  Gravity Touch bluetooth glove  is specifically designed to interact with augmented reality glasses like the Google Glass, Meta, Moverio BT or with the VR headsets like Oculus Rift, Samsung Gear VR, vrAse, Durovis Dive:

Those new products are amazing and they need new types of input devices. This instructable will describe how to build your own “Gravity Touch bluetooth glove” and I will also give you some tips to build your own Durovis Dive VR headset so that you will be able to enjoy full mobile VR. Because this glove will be of most use for VR game, I have created a Unity3D plugin for Android that handle the communication between your app and the glove. It means that you will be able to use your Gravity Touch glove to interact with your Unity3D VR game.

The Arduino code and the Java class I wrote to handle the communication between the glove and the Android device will also be available so that you will be able to adapt them for your need.

 

The bill of materials, among other things, contains an Arduino Micro , FreeIMU – an Open Hardware Framework for Orientation and Motion Sensing and 3m of flexible soft electric wire.

DIY Oculus Rift Tutorial

There are lots of reasons that someone might want a head-mounted display. Camera operators and radio-controlled vehicle enthusiasts typically like these because they keep the sun off of their screen while working outdoors. Aside from those practical purposes, strapping a high-definition display to your head is just cool. Add some motion […]
