Welcome! Good luck for your first time!
That's a lot of questions :p
Please use the section IDs (ex: D.9.c), instead of pages
1) These are OK. The first two are obviously OK, and even a JeVois camera is OK.
2) Bottom of the plant, as described during the presentation of the rules (not sure where is it written, though
5) Is it necessary ("only") to be in planters. Fragile plants not in planters are dead.
6) Partial contact of the bottom is enough. The wording is a but strange, both in French and English.
7) You can do whatever you want. My robot updates the current state, but it could be it's estimation of the end result. The only thing that matters is the result at the end of the 100 seconds. And it must not change after the 100 seconds (so that the referees can read it).
8) The start of the match. It will not be changed. You can see matches on YouTube to have an idea.
9) You are required to brake. It is thoroughly tested by a referee during the homologation, using a wooden robot moved by hand. Disabling the collision avoiding system is one of the worst offence, don't do that :p
There are cases of two very fast robot that collide slightly, it can be ok sometimes, if both brake, just not enough, and nothing is damaged. But that's up to the referees, they can also stop the match or one of the robot.
10) That' a typo: convex hull envelope. https://en.m.wikipedia.org/wiki/Convex_hull
11) Optional, but then you would be automatically forfeit against most of the teams (ex: my robot can only detect robots with a mast). Just build a robot with a mast.
13) Be easily detectable. Don't leave transparent/see-through sections.
14) The button is >20mm. The sima is >60mm.
Yes, collisions are not acceptable . Tip : if your robot stops at 90s, no need to detect SIMAs.
15) That's for historic reason: one team tried to get their mast-less opponent out for the match, by claiming that they needed a beacon. The beacon was an empty soda can, that they was not actually used.
On the other hand, some teams have actual embedded beacons : retro-recflectors, ultrasonic beacons, etc.
16) on-board = on top of the robot, at an 'altitude' of 430mm above the area (350mm+80mm of mast)
17) See answer 15
18) Contractual, not constructional
The models are just examples. The tables already built with the older (but compatible) wooden structure are allowed
19) You may use the half that is on your side (and painted by your color)
20) "switched on" is poor wording. Your robot can be already on before, but will start when you use the cord.
If there is too much delay between the cords, the match can be re-started by order of the referee
21) The rules should be clear enough
(Still not an official answer :p)
