Mini-bot Ideas
I've noticed that out of the 7 Mini-bot threads started so far, not a single one's purpose is to discuss the actual ideas, designs, and prototypes for making and deploying Mini-bots. So, without further ado, please feel free to post your ideas, no matter how ludicrous.

![]() LOL JK I think really strong magnets should do. Just launch it up from the base of the pole. |
Re: Mini-bot Ideas
duke how do like that sounds pretty ludicrous

Re: Mini-bot Ideas
I have to say, the last one they showed, the one with two wheels that are pulled against the pole by a weight, would be good, but placed on the pole, not moved out there by it's own power. A simple system of microswitches and latches should be sufficient.

Re: Mini-bot Ideas
One thing that really must be cleared before we begin designing our bots is wether we need to keep it up or just trigger the sensor at the top.
If I was given unlimited parts and access beyond the FTC parts I'd suggest a minibot propelled by small single burn rocket motors, replaced every game. That thing would fly. |
Re: Mini-bot Ideas
You only need about 4 newtons to trigger the target, no need to destroy the sensor.

Re: Mini-bot Ideas
i think the plan with my team is to use the main robot to "Launch" the minibot, rather than have it move under its own power. it should work alright. i also think that our mini-bot wont have any electrics, entirely potential energy driven.

I may be wrong but I believe we need to just trigger the sensor, but dont quote me on that. But it seemed that in the rule book it said we just needed to trigger the sensor |
Re: Mini-bot Ideas
well this is what my teams planning:

Re: Mini-bot Ideas
I really like the idea of a launched minibot, as opposed to one running under its own power. A section of PVC that could fit around the pole (1.75" internal diameter, 6 in long) is about 105g. Say, with some form of hinging and latching system to secure it around the pole (split in half, with hinges on one side and magnets on the other, maybe?), it could weigh in at 120g. That wouldn't take much to produce the 4N or so at impact to trigger the target. Several thousandths of a joule or so.

Re: Mini-bot Ideas
In response to my previous post, I figured out the initial launch velocity needed.
Assuming: -Kinetic minibots are allowed -4N triggers the switch (as indicated in GM 2.2.5) -A section of PVC around the tower with some hinging and latching weighs in at 120g -The target switch takes 1 cm to trigger -Friction turns off for the day The initial launch velocity would need to be 7.5 m/s. I rounded up gravity to 10 m/s^2 and rounded up most of my numbers to two sig. figures. This is on the outside for that weight of PVC. I think +/- .5m/s would be fine, depending on friction. |
Re: Mini-bot Ideas
I'm trying to convince my team to consider using Ytivarg to make the minibot climb the tower.

Re: Mini-bot Ideas
Our team's thinking of having a minibot with two plastic clips (like the bottom spring on an umbrella http://www.umbrellaman.co.uk/UserFil...n-Umbrella.jpg ) that would both have a curved side towards the pole, and then would maybe be attached to some PVC so the robot could lock on. However, having looked at the rules some more, I think it would be hard to make them/have them work without using springs. If anyone knows what I'm talking about, do you have any ideas?

Re: Mini-bot Ideas
Something our team learned is that the sensor that needs to be triggered is 3 limits switches wired in series positioned around the circle. So launching an item my trigger only one switch and no the other two in which case no score.
