'PICO in the Hospital'

Gostai-Jazz-500x500.jpg

Introduction

This course is about software design and how to apply this in the context of autonomous robots. The accompanying assignment is about applying this knowledge to a real-life robotics task.

Course Schedule and Lecture Slides

Lectures will be given on Wednesdays from 15.45h-17.45h from in Luna 1.050. The lecture of May 4 will be given from 10.45h-12.45h in Auditorium 11. The preliminary course schedule is as follows:

April 25 No lecture (see Canvas!)
May 2 Introduction by René van de Molengraft Tooling and Infrastructure by Wouter Kuijpers

Design Document

Hand-in a 3-page A4-sized design document as pdf (<1Mb) that pictures/describes the initial design idea with:

  • Requirements,
  • Functions,
  • Components,
  • Specifications
  • Interfaces.

You should upload this design document to your group's Wiki-page as this is a vital document in the design process. Make sure the document has been uploaded on May 11th, 17.00h. In case of questions about the document, consult your tutor.

Escape Room Competition

Scheme of a possible Escape Room, with measurements, but not up to scale!

Challenge Specifications

  • You have finished the assignment if PICO did not bump into walls and the entire rear wheel is across the finish line.
  • Do not touch the walls! Slightly touching is allowed, however, bumping (i.e., driving head-on into a wall) is not allowed! If PICO hits the wall, we decide whether it counts as bumping.
  • Every team has two trials (= max one restart). A trial ends if:
    • PICO bumps into the wall
    • PICO has not moved or has not made sensible movements (as judged by the tutors) for 30 seconds
    • The total time limit of 5 minutes per group is reached
    • The group requests a restart (on the first trial)
  • restart means:
    • PICO restarts at the defined start position
    • The trail time (= the time graded) is reset, but
    • the total time keeps running
  • Maximum speed (is limited in PICO): 0.5 m/s translational, 1.2 rad/s rotational.
  • There will be no second attempt if first attempt was successful

On the right you can find one example of a Escape Room Challenge.

Environment Specifications

  • The shape of the room is rectangular, the dimensions will not be given before the start of the challenge.
  • PICO starts at a random position in the room (but equal for all groups), PICO does not necessarily face the exit, nor a straight wall.
  • The orientation of the corridor will be perpendiculair to the wall.
  • The wall (on the far end) of the corridor will be open
  • The walls might not be perfectly straight, the corners might not be perfectly perpendicular, the walls of the corridor might not be perfectly parallel. The width of the corridor will be reasonable (somewhere between 0.5 and 1.5 meters).
  • At the exit, the finish line is located more than 3 m into the corridor. The walls that can be used to align PICO will be a little bit longer.

Robot Software

  • Make sure your software is easy to set-up, i.e:
    • Your software can be updated with one easy command, e.g. 'git pull'
    • Your software can be compiled using 'cmake' and 'make'
    • To start your software, only one executable has to be called
    • If your set-up deviates from this method, let your tutor know 1 week before the challenge!
  • The software of all groups will be updated on the robot before the challenge starts
    • This way, teams starting the challenge have as much time as teams that do the challenge at the end


Hospital Competition

Scheme of a possible Hospital, with measurements, but not up to scale!

Challenge Description On the right you can find one example of a possible Hospital setup.

  • PICO will start in the Hallway, PICO will start up to 1 m away from the parking wall and definitely not touching it. PICO might not be aligned perfectly with the walls, but the wall on which the parking has to be done is behind PICO at first.
  • After starting the software, PICO has to explore the (3-6) rectangular rooms of the Hospital, building a map, which will be needed for a later task. The doors inside the hospital will be (time-invariant) openings in the wall of about 0.5-1.5 m. It is possible that a room has more than one door (see Room 3 in the example), however it is not possible to drive in a loop.
  • During the mapping, one of the team members has to show the map being built and comment on the map and the operation of PICO. How the mapping is presented is left up to the groups, remember we would like to see the worldmodel and understand what PICO is doing. (you could use the io.speak functionality here!)
  • When the map building is complete, PICO has to park backwards to the wall behind the starting position. Parking is done upon touching the wall, assessed by the tutors. After PICO parked, PICO should say: "I am parked!" (io.Speak).
  • Upon touching the wall, a second executable could be started, note however that it has to be build before the challenge starts!
  • We will then place an object in one of the rooms, PICO has to find this object and stand still close to it and say: "I found the object!".
  • When PICO stopped moving close to the object, the challenge is completed.

Challenge Specifications

  • Do not touch the walls! Slightly touching is allowed, however, bumping (i.e., driving head-on into a wall) is not allowed! If PICO hits the wall, we decide whether it counts as bumping.
  • Every team has two trials (= max one restart). A trial ends if:
    • PICO bumps into the wall
    • PICO has not moved or has not made sensible movements (as judged by the tutors) for 30 seconds
    • The total time limit of 10 minutes per group is reached
    • The group requests a restart (on the first trial)
  • restart means:
    • PICO restarts at the defined start position
    • The trail time (= the time graded) is reset, but
    • the total time keeps running
  • Maximum speed (is limited in PICO): 0.5 m/s translational, 1.2 rad/s rotational.
  • There will be no second attempt if first attempt was successful

Visualization

  • Your code should save a snapshot of the model (e.g., using OpenCV)
  • The final snapshot should be saved after parking and can be used for presentation while pico finds the object

Robot Software

  • Make sure your software is easy to set-up, i.e:
    • Your software can be updated with one easy command, e.g. 'git pull'
    • Your software can be compiled using 'cmake' and 'make'
    • It is allowed to use multiple executables. Note that the Mapping/Parking-phase and Searching-phase can have separate executables, both have to be build before the challenge.
    • If your set-up deviates from this method, let your tutor know 1 week before the challenge!
  • The software of all groups will be updated on the robot before the challenge starts
    • This way, teams starting the challenge have as much time as teams that do the challenge at the end, compiling in between trials is not allowed.
  • If you use a separate catkin workspace
    • Make sure this workspace is compiled during the final testing hour
    • Building separate catkin workspaces during the final challenge is not allowed
    • The safest way to make sure your code works is by avoiding catking workspaces and including everything in your CMakeLists.txt

Hint

  • The following hint is provided regarding the location of the object:
The object will be located in the room for which most openings (i.e., doors) have to be passed through to enter it

Pico test schedule

- Be sure you have your software on git before coming to the test session so that you only have to git clone/git pull to get your code on the robot!

- Please charge the robot whenever possible so there is no down time due to empty batteries.

To submit for a timeslot you have to be logged in. Through the 'edit'-button for Pico test schedule, you can select a timeslot by typing 'Group <groupnumber>' behind the desired timeslot. - Submissions are last checked the day before at 22:00.
