"Fedor- Yes, we do plan to incorporate a MEMS IMU in an upcoming project. I don't think vision should replace a mechanical IMU, just complement it.
Monroe- This one most likely won't track stars since we're using pinhole optics and the…"

Fedor Korsakov commented on Travis Young's blog post A 350mg, Omnidirectional 6DOF Optical IMU/Optical Flow Sensor"Some of my research deals with HCI, and I'd love to see a way to step away from using cameras to track user's head and hands movements. Do you plan to incorporate an IMU into the system next? An integrated IMU+optical sensor module of such…"
Geoffrey L. Barrows commented on Travis Young's blog post A 350mg, Omnidirectional 6DOF Optical IMU/Optical Flow Sensor"Jack- You are correct in that each visual orientation provides the same general visual stimuli. However the pixels themselves are not exactly the same between orientations. It would be nice to have a proper gantry to do a full 6DOF test without…"
Jack Crossfire commented on Travis Young's blog post A 350mg, Omnidirectional 6DOF Optical IMU/Optical Flow Sensor"Since you oriented the sensor differently for each axis, you showed the different sensors gave the same reading when tracking the same features."

The ArduEye prototype (left) and the finished sensor (right) In a previous post, I demonstrated that the ArduEye platform could be used to prototype a 6DOF vision system for optical flow odometry. The goal is to make a vision…See More
Travis Young commented on Travis Young's blog post WFOV 6-DOF Vision System for Optical Flow Odometry using ArduEye and Arduino"@Monroe, it would be pretty easy to use this as a horizon detector, and we've demonstrated a light tracking application that could be used for the sun. More work (and probably more pixels) would be needed to pick out stars, but it is…"
Monroe Lee King Jr. commented on Travis Young's blog post WFOV 6-DOF Vision System for Optical Flow Odometry using ArduEye and Arduino"I wonder if it could be used for stellar navigation? Perhaps it could see the horizon the moon the sun? Perhaps stars? :)"
Travis Young commented on Travis Young's blog post WFOV 6-DOF Vision System for Optical Flow Odometry using ArduEye and Arduino"@Ellison, We will be offering the ArduEye system in the near future, but price is still TBD.
@Monroe, By providing integrated linear and rotational motion, this system can (theoretically) stabilize an air vehicle using vision alone. We…"
Monroe Lee King Jr. commented on Travis Young's blog post WFOV 6-DOF Vision System for Optical Flow Odometry using ArduEye and Arduino"I see! It would be useful then. Very interesting, I'll keep following this and see how it goes, Good Luck indeed with the tiny bee! :)"
John Hestness commented on Travis Young's blog post WFOV 6-DOF Vision System for Optical Flow Odometry using ArduEye and Arduino"@monroe, opticlal flow can be used to maintain position more precisely than GPS and also in areas that do not have GPS, like indoors. And it can be handled by a small on board processor. I don't know if it can do obstacle avoidance,…"
Monroe Lee King Jr. commented on Travis Young's blog post WFOV 6-DOF Vision System for Optical Flow Odometry using ArduEye and Arduino"Could this be used for obstacle avoidance? I'm not understanding the usefulness of the system? What can we use it for? "
Ellison Chan commented on Travis Young's blog post WFOV 6-DOF Vision System for Optical Flow Odometry using ArduEye and Arduino"Wow, that sounds great. What's the estimated cost for this? I'd love to test one out."

As a participant in the Harvard University Robobees Project, our primary task at Centeye is to develop a vision sensor system that will fit into a small flying robot about 2cm in size. The target weight budget for the vision system is 25 milligrams. While we still have a ways to go before achieving this, we…
