I really like your bots, but I feel they are way too strong compared to their flying alternatives.
1st, they have way too much range. I understand that they're not flying nor have a power need, but it is a bit too much when they can work outside of the player's vision compared to the bots' visible range : https://imgur.com/a/VNsPQ2A
2nd, they just straight up make personal construction bots & Roboports useless because they work much faster, got a greater range, and don't take any equipment slot or power. They're also much cheaper than bots with no limits on how many can be deployed at the same while bots are limited to 10/robotport. when I use both at the same 10 drones can complete most blueprints by the time a swarm of 50 bots even get to their location.
I like this mod, but I didn't expect an early-game drone to make personal bots useless.
