Upgradeable by tech equipment, available from the start to the endgame!

This mod provides basic armor and 4 special types of equipment from the start: Main Reactor, Main Battery, Main Servomotor, Main Roboport.

They are free to craft, but you can't use more than 1 item of each type in the equipment grid.
You can upgrade each of them after researching corresponding technology. There are 20 tiers for each, from red science to cryogenic.

Reactor will provide more power with each tier, Battery more energy capacity. You can supplement them later with original factorio equipment.

Main Servomotor provides bonus to player movement speed, while consuming energy. Both are increased with tiers.
Original exoskeleton is disabled for player armor(still usable in vehicles) for a balance reason.

Main Roboport allows usage of construction robots by player from the start. It consumes a lot of power, so you can't use it constantly at first.
Increases construction area, robot limit, charging limit and charging rate(max energy consumption too) with tiers.

Added Basic construction robots with small battery, available from the start (needs Iron gears and Electronic circuits to craft).
Original construction robots move faster now.

Main equipment can't have quality.
Armor grid sizes are customizable in mod settings.

New optional feature: Handcrafting drains energy in player's equipment batteries.

If you have less than 5% energy in batteries your handcrafting speed slows to 20%.
Each base second of craft time drains 100 kW worth of energy.
