VR Bowling Game Combines An Oculus Rift With A Wii Remote

August 13, 2014 by Matt Terndrup 5 Comments

[marclar83] was given an Oculus Rift so that he could prepare for an upcoming conference presentation. He began to download demos, getting familiar with the VR interface but was disappointed to find out that someone hadn’t developed a good virtual reality bowling experience yet. This prompted him to design a VR game that integrates a Wii Remote, recording the movements of the controller and sending accelerometer data to his computer.

The game he created is similar to Wii Sports Bowling but with the added bonus of being immersed in a virtual world with the Oculus Rift. The D-pad on the Wii Remote was programmed to switch stances and bowling methods, allowing the user to choose whether they want to throw the ball down the middle or curve it a long the way. Pressing the trigger button on the back started the swinging motion, and when released, the bowling ball shot down the alley at a high rate of speed crashing into the pins at the end.

Because the game was designed on the original DK1, the resolution of the images was a challenge that needed to be addressed, but [marclar83] solved this problem by implementing two user interfaces on the side of the screen that showed replays and depicted how many pins remained; proving to be a better experience for the gamer. This free public alpha version was made available for Windows, Mac, and Linux on the official VRBowling website. A video describing the project can be seen below.

Autonomous Helicopter Works Like A Wii Remote

autonomous-ir-helicopter

[Jack Crossfire] took one of those inexpensive indoor helicopters and made it autonomous. He didn’t replace the hardware used for the helicopter, but augmented it and patched into the remote control to make a base station.

The position feedback is provided in much the same way that the Wii remote is used as a pointing device. On the gaming console there is a bar that goes under the TV with two IR LEDs in it. This is monitored by an IR camera in the Wii remote and used to calculate where you’re pointing the thing. [Jack’s] auto-pilot system uses two Logitech webcams with IR filters over the sensors. You can see them mounted on the horizontal bar in the cutout above. The helicopter itself has an IR LED added to it that is always on. The base station follows this beacon by moving the cameras with a pair of servo motors, calculating position and using it when sending commands to the remote control’s PCB.

Don’t miss the demo video of the rig after the break.

Wii Remote Controling The Vehicle You’re Riding In

October 29, 2011 by Mike Szczys 20 Comments

Make sure your health insurance premiums are all paid up; if you decide to replicate this project you may need it. [Corey], [Kris], and [Jess] built their own go cart which is controlled with a Wii remote. The website has a poor navigation scheme, but if you hover over the horizontal menu bar you can get quite a bit of information about the build.

The cart has two motors which use a chain to drive each of the rear wheels. A pair of H-bridge controllers let the Arduino interface with them. It’s also has a Bluetooth module that makes it a snap to pull accelerometer data from the Wii remote. The front end looks like it uses rack and pinion steering, but you won’t find a pinion or a steering column. Instead, a linear actuator is mounted parallel to the rack, moving it back and forth at the command of the Arduino.

We can’t help but think back to silent movies where the steering wheel comes loose in the middle of a car chase. See if you get the same image while watching the demo after the break. This doesn’t seem quite as dangerous as adding remote control to a full-sized automobile, but we’ve played MarioKart Wii before and know how lousy the accelerator performance can be. Hopefully the firmware kills the motors if the batteries in the controller die.

Retake On A Wii Remote Controlled Balancing Robot

April 5, 2011 by Mike Szczys 4 Comments

[Tijmen Verhulsdonck] built his own version of a Wii remote-controlled balancing robot. He drew his inspiration from the SegWii, which was built by [Ara Kourchians].

The body is built using one of our preferred fabrication methods; threaded rod makes up a rail system, with three sheets of hard board serving as a mounting structure for the motors, electronics, and battery. This does away with the 9V batteries used on the original SegWii, opting for a very powerful lithium battery perched on the highest part of the assembly. It uses an Arduino as the main microcontroller. That detects roll, pitch, and tilt of the body by reading data from a Sparkfun IMU 5 board (we’re pretty sure it’s this one). Check out the videos after the break. The first demonstrates the robot balancing on its own, then a Wii remote is connected via Bluetooth and [Tijmen] drives it around the room by tilting the controller. The second video covers the components that went into the build.

This is impressive work for a 17-year-old. [Tijmen] lists his material cost at $800 but since he’s Dutch this might not be a USD currency.

Walking Motion Analysis Using Wii Remotes

March 1, 2011 by Mike Szczys 10 Comments

WiiGait is not a political scandal, it’s a project that records motion data while walking. [Bilal Chishti] and [Zassa Kavuma] are strapping a Wii remote onto each leg and recording the sensor data while making video of the walker at the same time. The two are using an Ubuntu box to pull the sensor data from the Bluetooth-enabled devices and utilizing its built-in webcam for the video. They graph the data for each axis and we’re sure that syncing up data anomalies with the video is just a matter of matching timestamps.

So what good is this? The creators are keeping us in the dark about an end-goal for collected data; this may just be for the experience of using the hardware. But we could see it having uses in making distance runners more efficient, or teaching that bipedal robot how to balance.

Wii Remote Connectivity For Android Devices

May 13, 2010 by Mike Szczys 42 Comments

[Pikipirs] developed an app that lets you connect a Wii remote to an Android phone. After the break you can see it used with a Sega emulator. The button presses seem very responsive, making for a nice gaming addition if you care to carry around the Wiimote in addition to your phone. It certainly seems to work better than the Wii remote + iPhone hacks we’ve seen. Pick it up from the Android store or download the APK from the thread linked at the top. This is an alpha version so don’t be shocked if it’s buggy.

Wii Remote Controlled Balancing Wheel chair

April 25, 2010 by Mike Szczys 10 Comments

The Personal Mobility Robot (PMR) has a chair for a passenger and balances on two wheels like a Segway. Now the clever folks at the University of Tokyo have added Wii remote control to the platform in a full-sized version of the Segwii. We understand that adding Wiimote control to anything isn’t exactly groundbreaking at this point. That being said, if using stock hardware can increase the quality of the user interface on something like a wheelchair, while decreasing the production cost at the same time, we’re all for it.
