The drag chains are doing the most. Most of the issue were bots with high speed conveyor and other type devices for ball control that were basically big Van Der Graph generators. They were very well insulated by the hard plastic wheels being used this year. Certain environmental field conditions make this much worse (like fields on top of ice rinks). The chains provide a ground path to discharge the large voltages that were building on the bots to the regolith and carpet discharging before they have a chance too short at the field boundaries. Not saying its entirely fixed, but things seem much better now....
