odor_bar

odor_bar is a visualization tool that displays the current odor concentration by the means of a bar of visualization_msgs/Marker (cubes in this case). In a (near) future we expect to add this functionality for other data besides odor concentration.

Subscribed Topics

nose (lse_sensor_msgs/Nostril)

• Chemical data from the MOX sensor(s).

Published Topics

odor_bars (visualization_msgs/Marker)

• A set of markers (cubes) proportional to the received chemical data.

Parameters

~bar_frame_id (string, default: /base_link)

• The frame_id of the odor bar. By default it moves with the robot.

~nose_frame_id (string, default: /base_nose)

• The frame_id from the nostril to extract the data from.

~scale/x (float, default: 0.15)

• The size of the x component of the cube.

~scale/y (float, default: 0.15)

• The size of the y component of the cube.

~scale/z (float, default: 0.15)

• The size of the z component of the cube.

~hsv_s (float, default: 1.0)

• The S (saturation) component of the HSV color space. It should be constant.

~hsv_v (float, default: 1.0)

• The V (value) component of the HSV color space. It should be constant.

~hue_max (float, default: 200.0)

• The maximum value for H (hue) component of the HSV color space.

~hue_min (float, default: 0.0)

• The minimum value for H (hue) component of the HSV color space.
