The Yocto-3D is a USB 3-axis accelerometer, gyroscope and compass. If you need to detect an orientation, a movement or a magnetic field, the Yocto-3D is what you need. This USB device provides a 3D accelerometer, a 3D magnetometer, a 3D gyroscope to measure angular velocity, a 2D inclinometer (tilt sensor), a tilt compensated compass and an inertial estimation of the orientation based on the 3D gyroscope.
All maths required to use this kind of sensors are handled directly by the device. You can mount it in any position, as the reference frame can be configured and taken into account internally by the Yocto-3D. The device automatically computes tilt angles and the estimated device attitude (using a quaternion, with an optional conversion to Tait-Bryan angles in the API). No additional computation is required in the application to determine the device orientation.
You can move away the sensor part as required, in particular if you want to avoid electromagnetic interference from other devices. Note that contrarily to the newer Yocto-3D-V2, this product CANNOT be calibrated to compensate for magnetic interference.
Caution: if you intend to use the compass function, you should not use classical Yoctopuce enclosures, as they include steel screws and magnets. Instead, use the YoctoBox-3D-Black/Transp enclosures, which do no include magnets.
To Pokemon GO users: Yoctopuce products work only with applications specifically designed to use them. On an Android phone, the Yocto-3D does not appear as a generic embedded gyroscope. If your Android phone doesn't feature any embedded gyroscope, the Yocto-3D can't help you to play with Pokemon GO.
If you are just interested in measuring tilt angles, you may want to have a look at the Yocto-Inclinometer
This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-n and to a GSM network using a YoctoHub-GSM.
USB cables and enclosures to be ordered separately.
Can I get in contact with you somehow? I have some good news for you!
Mr K, You can contact the Yoctopuce support. Since I'm pretty sure of what you are about to ask, no, the Yocto-3D will not work with Pokemon GO because it will not appear as a generic embedded gyroscope on your Android phone. Yoctopuce products work only with applications specifically designed to use them.
this will work with our phone for watching 360 and vr videos by cardboard?
@harshit kasera: only if your VR player has support for the yocto-3D, which is unlikely.
Is there a way to easily take in compass readings from this device into Matlab?
@jordan: Unfortunately not, so far we don't have any efficient Matlab integration. The best you can do is use our command line library, but that will not be fast.
is there a conda package for the libraries (in my case for cpp)?
@rg95: Sorry, but we do not have any conda package for our libraries.
Do you have any examples for how to combine Yocto-3D with Yocto-GPS to get higher frequency and better precision GPS coordinates? i.e. using a Kalman Filter?
@nrdvana: We have made some experiments offline in a previous blog post: https://www.yoctopuce.com/EN/article/accelerometers-and-gyroscopes-fantasy-vs-reality . We have never tried a live multisensor approach using a Kallman filter, but I suspect it would not be that easy. Augmented GPS navigation in cars is mostly done using odometers rather accelerometer, and there is a good reason for that: integrating MEMS accelerometer values does not add significant precision to a GPS-bases velocity measurement, and is not good enough be used to compensate for the lack of GPS signal
I just got a drone that uses my phone to control it. It needs my phone to have a magnetometer. My phone doesn't. Can my phone use this device to run the compass app ?
@Ludger: No: the Yocto-3D is not a system compass. It will only work with software designed explicitely for it, using Yoctopuce library
Can the Yocto-3D-V2 be used as inclinometer for VR glasses on pc-based systems?
Does it need some additional software for that? It would be great if Linux Simula OS could use it for glasses.
@vrgeek22 : probably not: the Yocto-3D-V2 will work with applications specifically designed to use it thanks to our programming libraries. But if you have access to your VR glasses software source code, and some programming skills, you be able to make it work.
