Re: pic: Team 188 Closer Look

well assuming two motor limited 2+ motor robots get into a pushing match. Their current draw can sky rocket to over 450 amps for a drill+chip or nearly 600 for this beast! Now what i was imagining is this robot locks its motors. I dont know the specific types of breakers used, but its possible to destroy stuff before something blows. if they dont have all the breakers working properly, they could probably melt even the 6 gauge wire itself pretty quickly.

I understand that locking the drivetrain is unlikely with so much power (unless of course a screw driver some how gets jammed in there ) But regardless, three motors seems useless. Basically, i dont understand why anything more than a drill and an FP is needed because when running both at max power, the total current draw is already pushing 130 or so. Why design something that has a maximum power that you cant even utilize. Also, three motors must introduce a very large amount of ineffeciencies because of motor curves not matching.

Because of the proliferation of 2 and 3 drive systems, I must have something very wrong in my analysis, or maybe i have discovered the key to the perfect drivetrain
