Walking robots, instead of standard flying bots.Some ideas for them:
- More costly
- Early research
- Lower speed
- More cargo (like a wooden chest maybe?)
- High battery
- Refueling at charging station / standard roboport
- Optional: different models, little and fast / giant and slow
- Optional: combat model ( kind of earth version of combat bot / mobile laser turret / mech warrior!)
I think implementing could be quite easy, their behavior would be identical to standard bots, with pathfinding (It could be copied from the biter?).
They can be useful in tricky zone with huge terrain fragmentation, where it's difficult building train stations. Imagine building "highways" with belts to increase their speed, or building walls around railways to avoid collisions. Packs of these things swarming your bases. The best could be a steampunk version, a mechanical spider with smoke fueled from coal.
