I think we need a poll to see which signals we think are most useful to include in a universal system.
I also know that some teams will want to augment their hand gestures with some form of signaling device, whereas others will not have the time/resources to plan that kind of thing in advance; as such, we should include both options in our final standard.
Example augmentations:
- Glove with different colors on different surfaces
- Traffic control wand or comparable pointing device
- Semaphore with several different colored flags/cards/surfaces
- Electronic sign with selectable shapes/patterns/signals
A few thoughts:
- Indicate location of boulder
(I think we can all agree this one is essential)- One hand points at the boulder
- Other hand indicates "boulder". Examples:
- Closed fist
- White flag/card
- Sign with a picture of a boulder
- Instruct a robot to move in a specific direction
(Useful for lining up with a goal)- One hand indicates the direction to move
- Other hand indicates "move". Examples:
- Raise index finger, rotate in circle
(example) - Pale blue flag/card
(to avoid confusion with the referees' penalty flags) - Sign with multidirectional arrows
(example)
- Indicate distance to target
(Goal, boulder, whatever)- Both hands raised
(example) - Bring hands together as the robot approaches the target
- When robot is in correct position, hands are completely together
- If robot goes too far, hands cross
