Autonomous robot's navigation

[ExDxV]

AVM Navigator v0.7.3 is released!

Navigator package is updated now and you can download next modification of AVM Navigator v0.7.3 from your account link.

Changes:
- The new "Back to checkpoint" algorithm was added in "Navigation by map" mode.




- Also new "Watching mode" was developed.
And robot can move to direction where motion was noticed in this mode.


Also common usability was improved.

By the way I received new video from user that succeed in "Navigation by map":

I believe that you also will have success with visual navigation by AVM Navigator module

Yet another video from user whose robot has extremely high turn speed but AVM Navigator module could control robot navigation even in this bad condition!

It is a testing of new robot for AVM Navigator project:

Nice effort! What video camera and software are you using?

[ExDxV]

I use in my experiments: Logitech HD Webcam C270 and 3Q NetTop Qoo (Intel Atom 230 1600Mhz) for images processing by AVM Navigator.

See here for more detailes.

This is an amazing project! Have you ever thought of using a Kinect?

This is an amazing project! Have you ever thought of using a Kinect?

The main idea of AVM Navigator project is the using only video camera as the main sensor of environment presentation.

But it works pretty well

It is enough difficult route that was passed by robot
with help AVM Navigator (route training and passing):


Autonomous navigation view from outside:


AVM Navigator v0.7.4.2 update

Changes:

- The indication drawing was carried to ::Annotate method


- Into camera view was added 3D marker of target position of robot


...

Fun with AVM Navigator



It's little demo of object recognition and learning from motion with helping of AVM Navigator.

All object rectangle coordinates are available in RoboRealm pipeline from external variables:
NV_ARR_OBJ_RECT_X - left-top corner X coordinate of recognized object
NV_ARR_OBJ_RECT_Y - left-top corner Y coordinate of recognized object
NV_ARR_OBJ_RECT_W - width of recognized object
NV_ARR_OBJ_RECT_H - height of recognized object

So you can use it in your VBScript program.

See here for more details.

Hi,

I noticed in the youtube video that you jiggle the object (your face or the book) slightly during the learrning phase. Is this an advantage?

Cheers,

Alan

In fact the AVM algorithm is not invariance to rotation and you should show the object for memorizing to AVM search tree under different angles during training for further correct recognition.
