The PX4Flow smart camera board will be released in a few weeks (designed by ETH, manufactured by 3D Robotics). There will be a ROS library to drive it, along with the PX4 libraries, Lionel Heng from the ETH Computer Vision and Geometry site announced on the ROS news site

I would like to submit a new repository for indexing:

This repository currently contains a ROS package for interfacing to the soon-to-be-released PX4Flow optical flow board (coming soon from 3D Robotics). We have plans to add a ROS interface to the PX4FMU autopilot, and software for MAV autonomy as showcased in our recent IROS paper ( ) in the coming weeks ahead.

Best Regards, Lionel Heng

ramboky: the on-board gyro is typically used to identify (and remove) the rotational component of flow about the axis orthogonal to the camera imaging plane.

Todd: the benefit of this sensor is that it can not only give more accurate flow estimates, but also handle more complex image/flow analysis tasks, such as image dilation estimation. This can be used in auto-landing systems to control vertical speed relative to horizontal speed, estimate approach speeds to objects, etc. This is very useful for doing vision-based guidance, but less necessary if you're closing your control loop with eyes and thumbs (i.e. manual control).

Any update on the release date for these?

Tim, I was wondering the same thing. The website has been saying that it "will be released in a couple of weeks" for the past two months.

I was in contact with the sales team at the start of November and they said they expected to release them late November, early December. Obviously that hasn't happened, so I tried contacting them at the start of this week. Unfortunately they've chosen not to respond... I'm guessing they think I'm pestering them... which I am, since I *must* spend my research funds before the end of next week or I'll lose them.

Perhaps if someone at 3DR sees this they might get some information for us and stop me having to buy something inferior from somewhere else (I will spend my money by the end of next week).

Tim, I'll check with the team and see what the current ETA is. I'm not sure who you were emailing, but as you probably guessed the sales team is not authorized to discuss unreleased products or potential release dates.

Just an update on this... Chris Anderson contacted me to let me know that while they haven't finalised a release date or price, they're still hoping to get them out before end-of-year. They have a few hurdles, but are apparently close to being ready to release these boards.

Curious if there is a status update (from Chris) on the release date.  I know how small engineering problems can turn out to be bigger than first thought.
