"Hi Nima, I am using these modules and seems like I have problem in 1 W. It is not stable when I set modules in maximum power. They loose communication more often that 0.5 W which I expect opposite. Any solution or idea? Thanks"

"Hi Oscar, I had my own troubles with the DNT900. I find the problem is the power supply. I don't use the SDK boards and have designed my own boards. On one of them, I sometimes have trouble when I hit 1W but on the other I don't so…"

"Thanks NS Rana. As for the project, we do it in our spare time and so development is bound to be slow. Developing all the electronics, software and mechanical components takes time!"

"Nima, I really enjoyed surfing your modified site, you have really done a great job, hats off to you ! Nima, but I realized that this project is bit slow on its various upcoming stages, and to me it seems like government project."

Project Andromeda - System Integration

The lack of updates on the Project Andromeda blog has been mainly due to the amount of work we've been trying to do coming up to the Outback Challenge competition. Unfortunately, we didn't quite make it this year but we've made a lot of progress on the different sections of the project. I've updated the blog with some new pictures and videos of our airframe, electronics and launch equipment. Check it out!…See More

Vision Based Collision Detection System

Posted on September 12, 2010 at 5:00pm 11 Comments

So I think we can all agree that a reliable detect-and-avoid system would indeed be the holy grail of the UAV world. The current debacle of UAV regulation hinges on the fact that UAVs indeed would not be able to avoid collisions as they would not be able to sense the presence of other traffic.


With the current technology at hand, it seems to me that vision based systems present the only option for small UAVs due to both…

For the gallery you could use a script like Lightbox. It's just standard Javascript and it needs next to no effort on your site. The cool thing is that if the user doesn't have JS available for some reason the gallery will still work like normal links to images.

Hi Nima, I noticed you work on DNT900... I'm working with the DNT900 Radios, but I have some problems when I configured the base radio with 1Watt of power transmit. For example in a test, the base radio and the remote radio were placed at a distance of 10 meters in a indoor scenario, the remote radio was joined by registering with the base radio, but after 40 minutes the remote lost the registered. I use the RFM eval boards. The eval boards are connected to 220V. The RFDataRate is set to 115.2 Kbps. When I set the base radio with 500mW, I have no problems... can you operate with 1 watt?... thanks...

Hi Nima,


I am using these modules and seems like I have problem in 1 W. It is not stable when I set modules in maximum power. They loose communication more often that 0.5 W which I expect opposite. Any solution or idea?


Thanks

Hi Nima,

Excellent work on the Andromeda prject...I am interested in using the DNT900 radio module for a school project. I have never worked with these modules before. If you can direct me to some resources about how to program these with c/c++. that would be really helpful. Also, I am trying to use raspberry pi (have past experiences with Arduino)with these modules. So, any help to start off, would be helpful. Thank you.
