Configure ada_feeding for Articulable Fork

[jjaime2]

Description

This pull request modularizes the entire ada_feeding stack to dynamically load the robot description, defines controllers and move groups, and updates static configurations for a specified end_effector_tool. When launching the ada_feeding software stack, setting the end_effector_tool to either fork or articulable_fork will require that the necessary hardware be assembled and connected, but will otherwise be able to complete the end-to-end feeding task in the same manner.

A prerequisite to testing these changes is having your development machine setup according to the Software Installation section of the Articulable Fork Assembly Guide

To test on the real hardware, first connect the appropriate hardware to your development machine via USB, e.g. for end_effector_tool = fork only connect the Jaco to your machine, and for end_effector_tool = articulable_fork connect both the Jaco and Articulable Fork to your machine

Testing procedure

• Run python3 src/ada_feeding/start.py --sim <real / mock> --end_effector_tool <tool> for each <tool> in fork, articulable_fork.
  • In RViz2, observe that the appropriate robot description has been loaded visually
  • Within the MotionPlanning window in RViz2, open the PlanningGroup drop-down menu and observe that the available options are ada, articulable_fork, hand, and jaco_arm. Set the PlanningGroup to hand for now, and toggle Displays -> MotionPlanning on/off to avoid visual glitches in RViz2.
  • When prepared (i.e. you think you can observe the motions ADA will execute for feeding), open the web application and click Start Feeding to move ADA into the AbovePlate configuration
  • In the camera feed, select a food item of interest (or in simulation, just click anywhere near the plate)
  • Be prepared to observe ADA's motion, then select any appropriate food mask,
  • Observe ADA's motion for bite acquisition, and verify that ADA moves above the food item and performs a downwards vertical skewer motion to acquire the food
  • Click the Move to mouth button, and observe ADA's motion as it orients the fork towards the front of the user's face
  • Click Continue and observe ADA move the fork towards the user's mouth, but stop after achieving a set distance
  • Click Move above plate and observe ADA move the fork away from the user's mouth, and move into the AbovePlate configuration
  • At this point, you can repeat bite acquisition if necessary. Otherwise, click Done eating and observe ADA moving into the Stow configuration

Before opening a pull request

• pre-commit run --all-files
• Run your code through pylint. pylint --recursive=y --rcfile=.pylintrc .. All warnings but fixme must be addressed.

Looks good overall. A couple nit-picks, but otherwise it looks good to merge.
