Re: Standard for ball handoff?

true, however I am picturing a a third baseman running the ball to the second baseman who in turn runs the ball to the first baseman. That would take so much more time than throwing the ball. However, a bad throw changes everything.

What about a really low throw, to where it is essentially on the ground, and reaches the next robot within a second or so?

Re: Standard for ball handoff?

A roll is always going to be more practical then a throw. Check the table below to see what I mean

Toss
  • Team A can toss: Team B can't catch (NO)
  • Team A can toss: Team B can catch (YES)
  • Team A can't toss: Team B can catch (NO)
  • Team A can't toss: Team B can't catch (NO)

If every team can pickup off the ground, and can bump the ball, a roll will always be more reliable. Also with a roll, both parties can give and receive. You are hitting %100 of unobstructed passes, taking a little more time, instead of 75% tossed. Unless you really need that catch bonus, roll will allow much more versatility.

I agree that picking up off the ground is a critical capability, since that is necessary to deal with a stray ball. However, passing on the ground runs the risk of interference from the other alliance. It seems like a direct handoff might be safer.

Re: Standard for ball handoff?

So interfacing with an unknown robot with a potentially incompatible transmission device that requires both parties to remain adjacent and relatively motionless and high risk of entanglement/ damage to critical game piece manipulation devices in a location where both robots are free game for ramming and general defense is safer than setting the ball on the ground and driving away for the other team to acquire it? Best of luck to your team.

The last time any "Standardization" of devices was proposed was in 2011 with minibots and minibot deployments. Nobody used that and teams who had spare minibots needed to work around their alliance members to add the bot + deployment + code. This won't work until FRC reaches critical mass with collaborative efforts, at which it wasn't then and it isn't now.

Exchange balls over the common medium, the ground.
