Eurobot Junior/Standard Experiment/Voltages

Post by Herobone » Tue 11 Dec 2018, 08:42

Hello everyone,
First of all I‘ve got a question too small to open another topic for:
[JUNIOR] Is it allowed to have a voltage greater than the allowed Cable voltage in the Bot? So is it allowed that the Robot has an extra power source?

The next questions concern both contests:
1. Is it allowed to activate the experiment via a radio signal?
2. Is it allowed to clamp the electron to the rope and move the rope via a motor in the experiment? So we would need to fix a roll on the oxygen atom.


Thanks in advance!

Yes, you can add an internal battery inside your robot (be careful on the security concerns). But the maximum voltage allowed inside the robot is 48VCC at any point.

Yes, but from the robot, not from the control panel.

Yes, it is allowed!

So it‘s also allowed that the rope goes both ways? So one going up and one going down?

Hello Herobone,

Sorry, can you explain, maybe with a drawing? We are not sure to understand perfectly your proposal.

Hi,
I meant it like this:

Sorry that i have to push this topic, but we really need an answer on this question. Were currently waiting for this answer to continue building the experiment according to the rules.

Hi Herobone,

A similar suggestion was made in another topic. I recommand you to compare your solution with the proposed one, as it was confirmed as valid by the referees (visuals and video here: https://twitter.com/LesKaribous/status/ ... 6579027968).

Suite à une réunion de la commission arbitrage, nous avons discuté de la question.

Le dispositif est parfaitement valide. J'explique pourquoi :
- le principe d'une cordelette « aller-retour » est bon dans la mesure où elle fait au moins la distance entre la zone d'expérience et la fente.
- la courroie crantée : valide aussi puisque le matériau est souple, non conducteur.
- le dispositif de fixation est aussi valide ; son unique fonction est effectivement d'accrocher/fixer la cordelette.
*Attempting a translation*

The solution is valid. Here is the explanation:
- Back and forth rope is valid since its length is at least as long as the distance between the experiment area and the pole.
- Toothed belt is a valid solution because it is flexible and it is not an electrical conductor.
- The fixation system on the pole is valid as its unique function is to attach the rope to the pole.


Hoping that answers your question :wink:
