The RS Media uses a lot (6 pcs.) of quite expensive D-size batteries.
And he consumes them quite qickly, so running him on batteries for a reasonably long time is indeed expensive.
Partial solution may be the use of rechargeable D-cells, but they
1. Provide significantly less voltage.
2.Are hard to find.
3.Are very expensive while their reliability and life-span is questionable.
4. It's also hard to find a sutable charger (actually, two as one charger typically charges not more then 4 cells).
5.The charging time appears to be uncomfortable long, ytnce at least two sets of rechageable cells will be needed (double expensive).
On the other hand, fortunately RSM have an AC/DC adapter but unfortunately RSM is blocking his lower body movements while powered from mains.
So, the question is:
Did anyone tried (or investigated how) to override such a fool-protection, obviously made to ensure the electric safety of children, supposed to play with RSM?
Personally, I think that with this protection disabled, RSM can be fully usable for the actions, that don't involve walking far in, say, one room space. So, battery would be needed only occasionally.
