This happened at our last tournament.
Robot A drives into the side of Robot B in the middle of the field.
Robot B is not against any field element but cannot drive forward or backward and cannot turn because Robot A is against the side of Robot B.
Robot B tries to move and the effort torques the drive motor(s) on Robot B.
Is Robot A in violation of <G11> ??
We cannot provide blanket rulings on mere snapshots of Match situations. However based on what you have described, this appeared to be a case accidental entanglement, which is not punishable by <G11>.
