Frequently Asked Questions 2020

1. General Questions

Q 1

Will we have to have our pilots take a test, register the UAS, and so on for UAE?

A

The UAS will have to be registered in the UAE, and we will provide more information about the registration process in due course. The pilots will need to be trained and have competence to operate UAVs.

2. Challenge 1

Q 2

Is the color of the ball fixed? In the document there is a rendering of a ball but the color is not specifically mentioned

A

The color of the ball will be fixed; we will provide more details on the color reference in due course.

3. Challenge 2

Q 3

What are the block properties in detail (size of blocks, material, weight)?

A

Please refer to Table 2 of the "Challenge Description" document: www.mbzirc.com/challenge/2020

Q 4

When is a block considered as built by a UAV?

A

A structure composed of bricks is considered as built by a UAV if all the needed sub-tasks are performed by the UAV: locating and picking bricks, transporting bricks, and laying bricks (either on ground or on other bricks, depending on the given target architectural pattern).

Q 5

During the challenge, can the UGV separate the blocks and the UAV place them? Is collaboration between the UAV and UGV allowed?

A

Yes, collaboration between the UAVs and the UGV is permitted

Q 6

What is the format of the wall pattern? (e.g. picture, text-file)

A

The wall pattern will be a numeric file with 3D information. More details on the format will be provided in due course.

Q 7

Is the pattern always the same or does it vary?

A

The pattern will be digitally pre-specified, and a new pattern will be generated for each team trial.

Q 8

Are the heaps of blocks sorted by color/block type or mixed?

A

The heaps of blocks will be sorted by size/color.

Q 9

Are the locations of the heaps, the initial position of the robots and the building spot of the wall always the same or do they vary?

A

The initial position of the robots will be the same. The locations of the brick heaps, and the building location may vary for each team trial; we will provide more details in due course.

Q 10

Do the walls have to be built in a certain position and orientation? Or can we just start everywhere?

A

The location (position and the orientation) of the wall will be specified prior to the team trial

Q 11

Is the building spot marked and if so how? (e.g. colored cross, painted L-shape, QR-tag)

A

The building spot will be marked by easy-to-recognize 2D features located on the floor. More details on the shape, size and color of the features will be provided in due course.

Q 12

Is it allowed to transport multiple blocks simultaneously with the UGV?

A

Yes

Q 13

Is it allowed to separate multiple blocks out of the heaps mechanically for instance with a mechanical wedge?

A

Yes

Q 14

What are the specific rules for each type of brick? E.g. Can a certain color only be picked up by UAVs, certain color can only be picked up by 2x UAVs, etc.?

A

TBD; we will provide more details in due course

Q 15

Will the bricks definitely be magnetic grabbable?

A

Yes, with non-permanent, ferromagnetic flat areas located on specific portions of the brick external surface. More details will be provided in due course.

Q 16

Approximately how many bricks will there be?

A

We estimate approximately 60 bricks of 4 different sizes. We will provide more details in due course.

Q 17

What is the maximum height of the wall? I.e. what UGV reach height is required?

A

We estimate this to be approximately 2m. We will provide more details in due course.

4. Challenge 3

Q 18

Will the UAVs be required to enter the building and fly indoors? If so, what will be the size of the openings?

A

TBD; we will provide more details about the building and openings in due course.

Q 19

What is the maximum mass of fire extinguisher that a UAV will have to carry?

A

We estimate the extinguishers to have a capacity between 1 to 3 liters. We will provide more details on the maximum weight in due course.

Q 20

How will the vehicles actuate the fire extinguishers?

A

The teams are free to develop their own solutions for triggering the fire extinguishers.

Q 21

How will the vehicles pick up the fire extinguishers?

A

The fire extinguisher can be pre-attached to the vehicles before the start of a team trial.

Q 22

How will the fires be simulated and extinguished?

A

TBD; we will provide more details in due course.

Q 23

Will there be a heat source that can be detected with a thermal camera? How should the fires be detected?

A

TBD; we will provide more details in due course.

Q 24

How should the fires be detected? Are there some markings or reference images you can provide for visual detection?

A

TBD; the teams are free to develop their own solutions to detect fires. We will provide more details about the fire specifications in due course.
