Hi to everyone at DIY Drones!I don't know much about UAVs, my specialization is the design of laser products. I recently made a laser range finder by accident that might be useful in UAVs.It started…Continue

A step closer to miniature, survey grade LiDAR

What is the difference between a low cost, hobby grade LiDAR and a much more expensive survey grade LiDAR? The short answer is that there are lots of differences. So the challenge becomes figuring out how to use the latest technology to achieve survey grade performance in a small, low cost package.Ideally, a LiDAR should have perfect…See More

DIY LiDAR scanner using the LW20 and a digital servo

Posted on February 20, 2017 at 6:23am 14 Comments

Making a small, low cost laser scanner for sense-and-avoid applications has been a objective of mine for several years. What makes this project challenging is the cost and complexity associated with motors and their drivers to provide the motion, position encoders to provide accurate aiming…

Making connections between ArduPilot and laser altimeters easier

We get lots of help requests from customers trying to configure the PixHawk and other flight controllers that are running ArduPilot software. The existing configuration interfaces, such as those found in Mission Planner, can be confusing, even for experienced users. We've introduced a "drone…

It's a good idea for high precision flight and landing altitude.

Hi LD,

Thank you for your considerate offer.

I think your device has very significant applications in what I am doing.

Please contact me at grmccray@yahoo.com.

I am very interested, but my primary interest is in using it for scanning for obstacles and openings.

The composite vision system I am currently working on extracts data from multiple (targeted) inputs and assembles it into an information matrix about the surroundings.

Most of the information I currently have available is short range < 10 meters. (structured light and laser scanner)

Your longer range device could provide a much needed extended look ahead capability.

It would be mounted on a pointable and scanable brushless gimbal.

In any case, please contact me at my above Email address.

Best Regards,

Gary

Hi LD,

Thanks for the kind offer. We are exploring the EMI system, but in any case it would be useful for the GPR based system (which has similar height control requirements). I cant say much about it yet but will post here when we've reached the next milestone.

If you are willing to provide one that would be great (ping me at dgorissen@gmail.com) and I will give due credit but no worries otherwise.

Thanks again

Dirk

Thank's Laser por compartir sus experiencias, me gusta ver las cosas nuevas, como se pueden aplicar en facilitar las tareas Agricolas, soy productora agropecuaria e ingeniera en produccion agropecuaria, si en algo le puedo aportar con mi opinion de usos en el sector no dude en comentarme.

Saludos
