Teleplot for ROS

Send ROS telemetry and data to Teleplot for realtime and rosbag plots that feels like a breeze.

Usage

1. Install Teleplot:
   • As a VS Code extension (Recommended)
   • As a standalone application
2. Launch / Open Teleplot
3. Customize and launch the appropriate examples in order to send relevant data to Teleplot :
   • Subscriber example, for real-time plots of robot telemetry
   • Rosbag example, using the rosbag API

All the examples were developed by following the names of the topics in The Canadian Planetary Emulation Terrain Energy-Aware Rover Navigation Dataset. This dataset is interesting, as its rosbags contains well-defined topics for GPS, IMU, power consumption, and odometry data.

Basics of Teleplot

Teleplot plots values that are sent with UDP packets on port 47269. These packets must comply to the following formats :

• varName:1234|g adds or update the varName variable value on Teleplot plots.
• varName:1627551892437:1234|g does the same, but specifies the value's timestamp in milliseconds for more accurate plotting.
• varName:1627551892444:1;1627551892555:2;1627551892666:3|g does the same as above, but publishes multiple values in a single packet.
• gps:48.636044,-1.511441|xy publishes two values to display an YX line plot

More specifications on the format are available in the Teleplot repository
