thanks for your response.
I see your points and you are right.
We need hard facts to check.
So let me rethink my thoughts:
I still think, we should stick to our voltage. Most good and inexpensive brushless controllers start at 10V, so we would make all these well approved driver-motor combinations to e-waste, if we drop the voltage level. I do not see the benefit of this kind of rule-changes.
And let’s face it: even if we drop the voltage to 5V, a well designed robot will surpass any lego-robots anyway. So please leave the voltage as it is.
Current limitations can be a way to reduce the power, but again, a kicking device that does not use pumped voltage but uses high current would burn a fuse and this is not intended by this rule change.
However, if the fuse is slow we could place a capacitor behind the fuse, so there would be a workaround.
But then we need a new rule as well, only allowing one battery for the whole robot, otherwise you will find teams sourcing out all “not-motor-components” the the unfused circuit.
Or, we just want this very idea. We have the fuse not for the whole robot, but only for the motors.
Then we actually could remove the fuse to see if all motors stop moving without killing raspberry pi or similar systems when switching off without a proper shutdown.
This in fact would also give the chance to use more powerful motors when designing a 3-mot-bot in comparison to a 4-mot-bot.
We could set international standards with car fuses and we could specify the exact fuse and even provide fuses for the competitions to make sure everyone uses the same fuse.
One last thought about speed measurement:
If you do not trust teams to provide correct datasheets than be sure they will cheat as well when driving a speed test. You cannot securely check the speed during gameplay and every robot can drive slower when in measurement mode, especially if a well designed robot has to fit to new rules by just beeing slower then before.
Thanks for allowing this kind of open discussion!
We all want to see fair and fascinating games and it is great to understand the thoughts behind rule changes.
