Autonomous anti poaching drone

I would be surprised if the noise were a problem at say 300ft but I have no idea exactly how loud the generator would be. My quads and hex get pretty quiet at 200ft away.

Not just the generator but also 8 props turning really fast. In the bush at night you will be amazed at what you can hear.

I do wish you the best of luck, it really isn’t an easy task. We had many other obstacles not mentioned to overcome like aircraft and system reliability (a big challenge, but one can overcome them). Enjoy, it should be fun.

Thanks, under no illusions as to how difficult this road is going to be and what this will cost to implement.


(Graham D) #25

Will follow with interest, please keep us updated.


(Robert Miller) #26

Will definitely do so. What ever this costs, we have to try everything we can otherwise soon the only rhino may be in museums

@panascape We http://www.ardupilotinitiative.com/whoweare/ have previous experience working in Africa using ArduPlane and machine vision systems to autonomously identify elephants and poachers. http://elephantswithoutborders.org/what-we-do/surveys/
I’d be very happy to have a chat with you Robert and see if there is an opportunity to collaborate.

Hi Craig, that would be great, thanks. I will message you with my email.

VERY interesting. I eagerly await further test results. I have other ideas of what to do with poachers, but will no comment on them here.:sunglasses:

The biggest hole we still need to patch is to get a UAV with a camera to take up station above an acquired target and track it. WE have the ability to identify targets but we don’t have the ability to move the camera to keep them in frame or to position the UAV.

There seem to be a number of projects built around keeping an object in frame using a pan and tilt camera but keeping the UAV in position seems to be more elusive. There are two other anti poaching UAv projects I know of and after having chatted to them, they too haven’t figured this out and will leave it till later which is a really bad idea.

So here is my idea and would love your input and aso if any of you want to help implement it, the assistance would be most welcome.

This would rely on using a fixed wing UAV and a 2-3 axis gimbal that can provide information about its angle of pan or tilt. If we don’t have such a gimbal, we would need code that we could use to calibrate the pan and tilt and then accurately keep a record of the angle we have moved it to.

If we fly our patrol patter with the gimbal panned at 45° from the nose and tilted 45° down (could be a different tilt angle) once we acquire a target we can do a very rough calculation of position taking the height from the ground via LIDAR and the angle of the gimbal. I know this won’t be accurate, but it doesn’t need to be.

As we keep flying the gimbal will track towards 90° to the nose and we start to to build a rough circle of loiter estimated for the gimbal to be at around 90°. Once we get close to 90° we initiate the loiter circle.

Now we will be out but we use various predefined points in the circle to make calculations based on height and gimbal angle and we use these to refine the centre of loiter with the gimbal tracking keeping the image in frame while we refine the centre of loiter. Once we have the centre within in an acceptable tolerance we will use the same method to move the centre of loiter as the targets move.

This may not work for say tracking a car but it should work for a human on foot, especially one who doesn’t know they have been detected and once we have established a good centre of loiter tracking them if they run should be far easier.

What do you all think?

If I am not wrong then the Solo’s I.mx6 has an object tracking feature in one of the smart shots. I think Tarot and Storm32 gimbals are supported. You could salvage a Solo I.mx6 and get your work done.
