I've already polled the Hero robot owners group about what modern batteries a Hero 1 can use

My inclination is to remove the HERO battery, open it up (nearly Dremeling is necessary), and have it rebuilt by Batteries Plus using comparable NiCads with modern amperage. That's what I did for an IBM Simon phone last year and it worked fantastically well. Rebuilt the two halves of the pack with epoxy and then sanded it flat.

Alex, let's talk (off-list) about when you can make another trip up here.
