Hero System ability design

So here's another puzzle: I'm looking at creating a combat robot as an NPC. It seems to me that such a robot ought not to be susceptible to telepathy or mental attacks or the like—in general, to EGO attacks. I don't see anything along these lines in the 6th edition Basic Rulebook. When I look back at 4th edition Champions, it suggests that automata should have EGO of 0 and be defined as immune to EGO attacks as a consequence. But that's -20 points to buy down EGO in 4th, or -10 in 6th. in other words, it seems that the robot is getting paid -10 points to be immune to an entire class of attacks!

I'm perplexed at the game logic of this. And I'm wondering about other ways of representing it. Looking at Life Support, I see that immunity to all forms of poison costs 5 points, and immunity to all diseases costs 5 points. So maybe immunity to all telepathic interaction with other minds should cost 5 points, or 10?

Alternatively, we could say that a robot that can be reprogrammed by the methods we now use for computers has a different form of EGO, one that doesn't respond to telepathy but does respond to jacking in and wi-fi and such, and that this is a 0-point change of mode. Champions doesn't seem to have that concept, but maybe it should be introduced.
