Quadcopter with Kinect doing altitude hold and obstacle avoidance



More from the Berkeley team we wrote about earlier, now with better documentation. From I Heart Robotics: "Patrick Bouffard from the Hybrid Systems Lab at UC Berkeley has done a great job documenting the ROS 3D Contest entry shown below. So it should be easy to reproduce the results if you are lucky enough to have access to a Kinect and an AscTec Pelican quadrotor."

 

They also note that Ascending Technologies is offering a 15,000 Euro sponsorship for a team doing UAV research. Proposals due by February 13th.

 

And I can't help but notice that there's a bit of Berkeley robotics cluster forming. Along with all the UC Berkeley research, there's DIY Drones, Berkeley Bionics (exoskeleton makers), 510 Systems (who made Google's robotic streetview cars) and the work at theLawrence Berkeley National Lab.

We are ready to join the contest ... :) We have multipilot 2.0 for stabilization and atom board to put on our quad ROS and kinect ... I'm yet doing some test on kinect , ROS and URBI too ... Who whant help me ?!?

This is my next step after MP2.0 ... We use Ubuntu X86 OS and an ATOM board onboard.

I've been wondering whether it would be possible to reproduce the same with ArduCopter + BeagleBoard + BeagleROS + Kinect with the overall cost down to about 1000Eur instead of 7000Eur as with AscTec Pelican + Atom board.

Any one out there has already had some success using BeagleBoard + Kinect?

I think that is better to use Atom instead of Omap because ROS for Omap is not updated as Atom  x86 revision of code .. It's wrong ?

I'd agree with you Roberto. I've used an IGEPv2 (beagleboard clone) board before and it is painful having to recompile everything specifically for it. I eventually got an Atom COM which has definitely simplified development. With it I have implemented an interface to my Mikrokopter using the normally unused USB port, with the ATOM  running ROS on ubuntu. The development become easier because you can use a normal pc with ubuntu installed for the development and testing, then deploy the ROS packages onto the onboard ATOM and pretty much be guaranteed it will run.

 

The disadvantages are extra weight and cost, but you do get more processing power.

 

My project has stalled for now as I have realised how much of the vital code is missing from the Mikrokopter public repository so I am switching to the APM platform. Eventually I'd like to explore using the Kinect sensor, or preferably the Primesense Kit if I can get my hands on one.

 

I'm definitely looking forward to your Multipilot 2 board Roberto.

Don't get me wrong please, I wasn't trying to discourage people from taking part in the competition or joining Roberto. Just asking, if someone out there interfaced Kinect from BB-xM already. I'm also not questioning the possible ease of development that Atom is offering. But for many individuals the tenfold price difference means a lot when taking a possible crash under consideration.

@Luke: I think 1GHz processing power is enough already.

Hi Tom,

 

Equally I didn't mean to discourage you, I just wanted to convey my experience with both. Also I think you'd be surprised at the cost of the COMs being sold now, you can get them for around 3 x the cost of a beagleboard so not as expensive as you might think, but still a quite a bit of money to put in the air.

 

I'd be interested to hear how you get on with your beagleboard, ROS and Kinect. 

 

Cheers

... I choose my x86 board to add to Ardupilot32 . Is developed in italy by Eurotech based on atom cpu. My idea is to develop a carrier board for AP32 that support connection with this atomboard

this is an a picture of that board.

@Tom @Luke,

The price of Atom board is around 400 euro for a sample... instead of 140 .. so is not so different . But the software  is ready to use , so i think that the price that you save you need to spend in man hour to port the code on beagle board .. but the problem is not the first porting , but the continuous upgrade , patch ecc ecc .

Regards

Roberto

Ok, so this is something I didn't know. According to the pricing list I received from AscTec a couple of days ago Atom board costs 1200Eur, which is 1632$, which is more than 10 times more than the 149$ for BB-xM.

Is there a company which sales them any cheaper, or do I have to ask for sample at AscTec to buy Atom for the price you mentioned Roberto?
