Frequently Asked Questions 2020

1. General Questions

G. Q1

Regarding UAV size constraints, the scoring scheme has mentioned that all extensions should be done after take-off. Is there a penalty if the extension happens before take-off?

A

Extensions should take place after taking off, no extensions allowed before taking off.

G. Q2

While landing, should the drones confirm to the size constraints (that is, should all extensions be retracted before landing)?

A

No

G. Q3

Is take off zone and drop zone the same?

A

No

2. Challenge 1

CH1. Q1

About 3D Figure-8 target ball trajectory, could you give more details.

A

The target ball Altitude will be between 5m and 15m. The ball will be at least 3m away from the arena side netting. The balloon heights will be less than 5m, and will be below the moving target altitude.

CH1. Q2

Is there any constraint for landing after challenge is finished for the drones?

A

The drones have to land inside the arena after the completion of the Challenge.

3. Challenge 2

CH2. Q1

In the mesh design given to us for Challenge 2 (picture attached above), what are the sizes of the individual mesh grid?

A

The individual mesh grids are diamond shaped, with diagonal lengths of approximately 70mm x 36 mm (in the major and minor axes directions).

CH2. Q2

Could you provide further information about the randomly generated blueprint? How it will be conveyed to teams? And How to read the information

A

Please refer to the Appendix A below.

4. Challenge 3

CH3. Q1

We were wondering, whether it is a requirement for the UGV in Challenge 3 to drop the blankets on the fire. Is it ok if we just drag the blanket onto the fire, wait for a defined period of time and then proceed to the next fire with the same blanket?

A

You may drag the blanket to the fire sources. However, the UGV must release the blanket on the fire target.

CH3. Q2

Do we need to carry 2 blankets at the same time if we want to use the UGV for extinguishing both outdoor ground fires?

A

You may mount two or more blankets on your UGV at the start of the trial.

Appendix A - Challenge 2 Wall Blueprint Description

Every team will receive two text files, Wall 1.txt (for Wall 1) and Wall 2.txt (for Wall 2) in a USB memory stick, just prior to the commencement of the trail.

Wall 1 (UGV) Blueprint

Wall 1 will have 2 segments; Segment 1 will have 5 layers of Red, Green and Blue bricks. Segment 2 will consist of 5 layers of Orange bricks. The Wall 1 segment numbering scheme is shown in Figure 1, and both numbering schemes are valid for scoring purposes.

The file Wall 1.txt will contain the blueprint for Segment 1 of Wall 1. An example of a randomly generated blueprint is given below, where R, G, B represents the colors Red, Green and Blue respectively.

The corresponding wall layers are:

  • Layer 5: (Left) R R R R B G G (Right)
  • Layer 4: (Left) G R R G B R R (Right)
  • Layer 3: (Left) G R G B R R R (Right)
  • Layer 2: (Left) R G R B R G R (Right)
  • Layer 1: (Left) B R R R G G R (Right)


Wall 2 (UAV) Blueprint

Wall 2 consists of 4 segments. Segment 1, Segment 2 and Segment 3 consists of two layers of Red, Green and Blue bricks. Segment 4 consists of two layers of Orange bricks. The Wall 2 segment numbering scheme is shown in Figure 2, and both numbering schemes are valid for scoring purposes.

The file Wall 2.txt will contain the blueprint for Segment 1, Segment 2 and Segment 3 of Wall 2. An example of a randomly generated blueprint is given below, where R, G, B represents the colors Red, Green and Blue respectively.

The corresponding wall layers are:

Segment 1

  • Layer 2: [(left) G B R G R R R (right)]
  • Layer 1: [(left) R G G R R R B (right)]

Segment 2

  • Layer 2: [(left) R G G R R R B (right)]
  • Layer 1: [(left) R B G R G R R (right)]

Segment 3

  • Layer 2: [(left) R G R R G B R (right)]
  • Layer 1: [(left) G R B R G R R (right)]
