My university is looking at purchasing an egg-bot for promotion of engineering on open days and such, they seem like just what we are after but i am concerned they may not be reliable enough for our needs. We have several robots and promotional things that are cursed with reliability problems. Could this thing run for 1-2 hours at a time more or less constantly without any big issues? And how prone are servos to breaking
Specifically im worried about the pen servo, in my experience tower-pro servos are incredibly prone to broken gears. I notice they are a low cost clone of the hitec hs-55, which are a much better quality servo. Does this mean if i got a hs-55 separately i could use it as a drop-in replacement to make it more robust?
