Details of the scenarios used in the first qualification task

This page details the specifics of the scenarios that are used in the first ARIAC 2018 qualification task.

The following applies to both scenarios:

• The use of any 'cheat' interfaces is not permitted and will be blocked in the automated evaluation setup.
• The trials have a time limit of 500 seconds. Any unsubmitted shipments when the time limit has elapsed will not be scored.
• Simulation state logging will be enabled via the gazebo_state_logging: true setting in the the trial config file, like this.

Part A

Part A is released for teams to practice with. It can be run with the following command, being sure to specify your team's environment configuration file:

rosrun osrf_gear gear.py -f `catkin_find --share --first-only osrf_gear`/config/quals/qual1a.yaml <path_to_your_config_file>.yaml

The scenario for Part A has the following characteristics:

• There are two orders of one shipment each:
  • The second order will be announced part-way into the completion of the first order.
  • Shipments from both orders can be submitted after this time, but the second order is higher priority and for maximum points it should be completed as fast as possible.
  • The second order does not have a time limit, but should be completed as fast as possible.
  • To complete the second order, teams can choose to remove the products already in the shipping box(es) or switch to an empty shipping box.
  • After the second order is complete, the first order is to be resumed.
• Faulty parts should not be used to build the fulfill the orders. See this page for details on working with faulty products.
• The second order contains products that must be flipped. See this page for details on working with flipped parts.

Part B

Part B is not released for teams to practice with. In Part B teams will be presented with a previously unseen scenario and their software must be able to adapt appropriately.

The scenario for Part B has the following characteristics:

• All agility challenges released at 5 March 2018 may be present:
  • Faulty products.
  • High-priority order interruption.
  • Flipped products (only the pulley_part product can be flipped).
  • Insufficiently many non-faulty products available for order completion.
• There will be at most two orders, each made up of at most 2 shipments.
• The same 5 storage bins used in Part A will be positioned in the environment.
  • Some storage bins may be empty.
  • There will be at most one type of product per bin.
• Users do not have control over the positioning of the quality control sensors, they will be in the same location as for Part A.
• The following product types may be used in the order(s): gear_part, piston_rod_part, pulley_part, gasket_part, and disk_part.
  • Logical cameras will refer to model types by these names. They will also report shipping_box models.
  • Pulleys are the only products that can be requested to be flipped.
  • All products will start in the storage bins un-flipped.
