Autonomous robot's navigation

 I finally got my hands on a Roomba robot that I could try with the Nav programs. I went through all of the items and tutorials. When I placed the robot in the NAV mode, it moved. All others did not move unless I used the arrows to train them. The Nav by map mode showed the progress, but I could not get it to move by clicking on Left mouse. When I clicked on Left mouse it did not do anything. I would like to make that work. Can it work on it's own, or do I have to train it in one of the other modes?

I prepared simple video tutorial "Route training and navigation by map":

See more details about tuning of "Marker mode" and "Navigation by map" modes.

It's test of new algorithm for AVM Navigator v0.7.3. In this video was demonstrated how robot just try to go back on checkpoint from different positions of the learned route.

First in video the robot has received command: "go to the checkpoint" and when robot arrived to the checkpoint then I brought robot back (several times) in different position of learned route. When robot noticed the changes then it indicated that robot was displaced because any commands were not given by robot to his motors however changes were seen in the input image.

Then robot started looking around and localized his current position. Further the robot just calculated path from current position to the checkpoint and went there (and so forth).

EDV:
Hi guys,

I'm still working over AVM technology. Now I've founded my own company that is named Invarivision.com.
We are small but passionate team of developers that are working over system which would be able watch TV and recognize video that interests user.

And we need your help!

It seems that interface of our search system is good enough because we try to make it to be simple and user friendly but from other point of view it could be a total disaster.

Could you  please take a look to our system and then tell us about good and bad sides of this?

The constructive criticism is welcome.

With kind regards, EDV.

jwatte:
How does your algorithm deal with offset, rotation, scale, and mirroring of the "trained" object/source ?

EDV:
Algorithm AVM uses a principle of multilevel decomposition of recognition matrices also it is steady against noise and can work with images that were offset or scaled but it does not invariant to rotation or mirroring.

Our search system also is the robot that watches TV like a human but does it simultaneously on several TV channels and this robot can watch TV nonstop and do not to get tired  :)


--- Quote from: Cbenson ---Can you explain more about how the system would determine what video interests the user?

The user just uploads video which interests him to the search system and then system would search it on all channels that are scanned.

Also user can add own TV channel that interests him if system still does not have such channel.

So, in other words: AVM Video Search system provides service that allows customers to make audit of TV channels or searching of forbidden or copyrighted video in file with help of automatically recognition of the video content.

The main advantage of this system is direct recognition of separate images into analyzing of video content that is provide searching of very small video fragments about two seconds long.
