Introduction

Training Technology Lab uses MATLAB for most data processing and visualization purposes. Several scripts have been written to work with our various technology. Here is a list of the scripts:

  • Rosbag extraction.m
  • EMG analyzer.m

Rosbag extraction

Official methods:
Viewing: For viewing video stored in a .bag file, rqt_bag is the standard tool.

Extraction: To extract video (which are just compressed/uncompressed images) several methods exist. We have often used bag2video.

MATLAB scripts:

rosbag_loader.m Converts .bag files into .mat files. Must be done before using the other 2 scripts

rosbag_plotter.m Automatically plots known data formats)

rosbag_video.m Automatically converts rosbags into .avi files with data plot overlays.

EMG analyzer

Purpose: For analyzing EMG data recorded with Myon electrodes and ADInstruments AD converter via ROS-setup in Training Technology Lab
