Hey guys, I read through the rules but I think I just missed it. How many totes can the robot hold at one time?
As many as you can.
I think the field has about 100 of them, but maybe only around 60 that you can access…
I have not yet found a rule limiting the number of totes that a robot can possess.
128 of them and 70 you are able to get 
(to be specific lol)
There is a maximum number of 70 totes
30 from the alliance station
28 in the landfill
12 on the step
There is a potential chance of having access to more totes if the other alliance accidentally knocks their stack onto the other side.
