Tether rules?
What are the rules for tethering to another robot exactly, does the second part have to have power supplied to it?

Re: Tether rules?
Nope. As long as it's attached (regardless of power supply), it's considered part of the robot, but all other rules still apply. It has to fit within the transport config, be under 120 pounds, and it might require a re-inspection, depending on the scenario.

So does that mean 1114's ramp at the human player station would need to be tethered to be legal?

Yes, it needs to be attached to be considered "one robot" and one robot can only have one battery and one roboRIO. A COTS computer on the ramp can not power anything other than itself - do not much use. BTW: if it is a dumb ramp, the tether could be a string or even dental floss. Something the ref wont trip on while walking the field. |

We added a tether ramp to our robot at our first district. Unfortunately we didn't get it working till the end of our competition but we look forward to using at our next district.

The only reason that I know that that particular ramp is yours is because you said it is. The refs on the field might see the tether. But if multiple robots on the field have those things... Please reference the Blue Box in R02, as modified by the 2/17 Team Update, and fix the lack of numbers on the ramp when you get the chance. Your referees and inspectors will thank you. |

Re: Tether rules?
There is no requirement that any specific part of a robot (in this case a tethered component) be powered at all. A COTS part with an internal battery could be used, but that battery is not allowed to power any actuators, just do sensing and processing. If you did need it to have a bit of power but didn't want to run wires, it could be powered by a spring or by harnessing the energy of totes falling on it. I can certainly imagine a stacker (similar to Robin) that built a stack without electricity, working entirely on mechanical triggering and powered by energy stored in a spring. If the spring only held enough energy to make one stack, you could include a windup powered by a CIM on your version of Batman.

This game has officially jumped the shark.
