dish_viz: Main Page

dish_viz: This package provides a visual representation of dish states.

dish_viz is a ROS package for visualizing the activity of a neural network. Spikes and centers of activity are plotted in sync with the movement of the ARM, allowing for a visual representation of what is causing the movement. The package consists of a single node, and relies on the other packages in the arm_project stack to perform properly.

codeapi

Run the visualizer node by creating a DataHandler object.

To initialize the visualizer: DishVisualizer::init
To update voltage data for a channel: DishVisualizer::update
To update the center of activity: DishVisualizer::updateCa
To redraw the visualizer screen: DishVisualizer::redraw
To set volt ranges for each channel: DishVisualizer::setVoltRanges
To correct ranges: DishVisualizer::setMinVolt and DishVisualizer::setMaxVolt

List of nodes:

dish_viz

dish_viz

dish_viz receives dish states from a receiver node and then plots that activity on screen for the user to see. It also receives centers of activity from the CAT creator node and plots those as well. This node is in sync with the movements of the ARM.

Usage

$ rosrun dish_viz dish_viz
