NV_LOCATION_Y - current location Y coordinate NV_LOCATION_X - current location X coordinate In this mode you should point the target position at the navigation map and further the robot plans the path (maze solving) from current location to the target position (big green circle) and then robot begins automatically walking to the target position.įor external control of "Navigate by map" mode is added new module variables: You just should manually lead the robot along some path and repeat it several times for good map detailing. Marker mode provides a forming of navigation map that will be made automatically by space marking. In new version is added two modes: "Marker mode" and "Navigate by map". Now AVM Navigator v0.7 is released and you can download it from RoboRealm website. ExDxV Posts: 25 Joined: September 30th, 2010, 7:01 am
If robot can't recognize anything (gate/object) then robot will be turning around on the spotįor searching (it may twitch from time to time in a random way).įor more information see also thread: "Autonomous robot's navigation" at Trossen Robotics. So, if robot will walk by gates and suddenly will have seen some object that can be recognized then robot will navigate by the "follow me" algorithm. In the end of the route you must click on the button "Set checkpoint" and then robot will turn several times on one spot and mark his current location as a checkpoint.
In "Nova gate" mode and then you must drive the robot manually by route (the gates will be installed automatically). Field of gates is painted blue if the gates do not participate in this route (weight rate 0), and warmer colors (ending in yellow) show a gradation of "importance" of the gate in the current route.įor training of the route you have to indicate actual route (button "Walking by way") At the bottom of the screen was added indicator "horizon" which shows direction for adjust the robot's motion for further movement on the route. The gate data contains weights for the seven routes that indicate importance of this gateway for each route. Of robot on the center of the first recognized object in the list of trackingĪnd if the object is far will come nearer and if it is too close it will be
The navigation algorithm do attempts to align position of a tower and the body The Navigator module has two base algorithms: So, you can try now to review my experiments with using AVM Navigator. I embodied both algorithms to Navigator plugin for using within RoboRealm software. Since October 2007 I developed new object recognition algorithm "Associative Video Memory" (AVM).Īlgorithm AVM uses a principle of multilevel decomposition of recognition matrices, it is steady against noise of the camera and well scaled, simply and quickly for training.Īnd now I want to introduce my experiment with robot navigation based on visual landmark beacons: "Follow me" and "Walking by gates".
