Purpose

The goal of this data collection is to curate a dataset of force/torque and audio to help us classify whether peeling has been done successfully. To do this we will be collecting four different types of data across various food items. These types are:

• Sliding over skin
• Sliding over flesh
• Peeling skin
• Peeling flesh

The idea is that the first two types of data will be done after a peeling action has occured. The key insight is after we peel, will feeling the region we believed we peel help us figure out if we actually peeled. One downside to doing this is that it requires two actions to figure out if we peeling. First we need to peel and then afterwards slide over the suspected peeled region.

The last two types of data will help us detect if we peeled during peeling, which means we only need one action.

Setup

A terminator layout has been created so that all terminator panels and commands can be quickly run. To use this layout type the following command in terminal or terminator: terminator -l data

This will open a terminator with every panel in the correct directory, the necessary panels will have sourced the workspace, and the conda environment should be activated. Here is a picture of what the screen should look like:

In case anything goes wrong here are commands that are run in each window. All of these are in the ~/peeling_ws/ directory and have sourced devel/setup.bash (with the expection of rosbag record which is in ~/data/) starting from the top:

• roslaunch data_collection collect_data.launch (If doesn't work, make sure you've used conda activate peeling to activate env)

In the second row moving left to right are the following commands:

• rostopic echo /audio/audio
• rosrun rosserial_python serial_node.py /dev/ttyACM0 (the middle top window) IF ERROR "Device or resource busy: '/dev/ttyACM0': run fuser -k /dev/ttyACM0
• rostopic echo /force (the middle lower window)
• rostopic echo /key_continuous (If this says 'message not built', please make sure that you've sourced the workspace)

In the third row from left to right:

• rosrun data_collection key_input.py (If this doesn't work, please make sure that workspace is sourced, and you've used conda activate peeling to activate the environment
• rqt

In the fourth row from left to right:

• (disregard this for now, look at the next bullet point) Nothing is run currently but you should run the following: rosbag record /audio/audio/ /force /key_continuous -O <fooditem_#>.bag
• rosrun data_collection publish_key.py (If not working, make sure to source the workspace, and you've used conda activate peeling to activate this env)
• roscore
