George’s Status Report 4/29/2023

  • Worked with Jack to get create dummy_laser node
    • Created bin identification algorithm that uses edge detection to identify bin from laser data
    • Identify bin using L1 norm during bin rotation through lidar scan window
  • Worked with Jack to calibrate docking procedure
    • Experimented with lidar bin identification (dummy_laser), and were unhappy with results
    • Added support for second back camera to also detect ARuco tags
      • Docking procedure uses a mix of ARuco and Lidar distance estimation to control movement logic
    • Added additional state-machine logic for docking protocol
  • Worked with Jack to make rotation direct drive commands more robust
    • Uses transform listener as a feedback loop to get back robot position w.r.t the map
    • Rotate algorithm rotates to goal angle using current published position

Schedule:

Behind on schedule, using finals week for full integration testing and integration

Next week:

Finish bin docking integration test, complete the rest of the state machine logic

Testing Plans:

  • Worked with jack on preliminary bin alignment for bin docking subsystem test
    • Changed design to include 2nd web cam after finding lidar object detection being unreliable
    • More robust docking test with arms to lift bins are needed
  • Integration testing left for next week after hardware freeze is done
  • Completed another battery lifetime test 80% battery drainage over 4 hours.
