TL;DR
When a spidertron is in contact with a power pole, spidertron batteries and robots should recharge much more rapidlyWhat ?
Spidertron batteries and personal roboport robot recharging make sense. But it should be possible to go "plug-in"by making contact with a power pole. When in contact with sufficient grid power, spidertron should recharge much more
rapidly, perhaps 3x or even 10x the normal recharge rate.
Why ?
The natural recharge rate has a nice balancing effect on the game, particularly when spidertron is out foraging farfrom your factory. But when you're making massive changes to a megabase, the delay in recharging your own bots and
the bots in your spidertron can feel very limiting. As a compromise, allow a spidertron to connect to grid power when
standing on a power pole, and to thereby receive a far more rapid rate of recharge.
