I love to tinker and like most tinkerers I have lots of spare parts, some broken and some not. So I was messing around with robots and got carried away. Since the final mods to robots and stuff to make them work, is now better, I uploaded these changes for others.

This mod focuses technology on roboports, construction and logistics robots within the game.

Added 4 tiers of robots (logistic and construction):

Mk2: Max energy storage 2.33 times more than base. Speed is 50% then the base.
Mk3: Energy usage while idle is 80% of the base robot. Robot speed in increased by 33% over the Mark 2. Cost to for the robot to move is reduced by 50%
Mk4: Robot speed is increased by 3 times over the Mk3. Cost for the robot to move is increased by 62.5%, mostly due to the rocket fuel being strapped to the outside of the robot.
Mk5: Robot speed is increased by 25% over the speed of the MK4, and since radiation from the nuclear fuel is used to maintain high rate of speed, it costs 12.5% as much energy for the robot to move compared to the MK-4.

Added 4 new roboports:

For the two of the roboports, Construction and logistics radius increases 100% between the base roboport and Mk2, with another 200% increase between the vanila and Mk3.

The other two roborts, have reduced logistic and construction radii, but respectively can recharge either 12 or 24 robots at the same time.

Added a new personal roboport:

The personal roboport Mk3, has 6 charging ports, and a 40% increase in logistics and construction radii.

The robot recaller will recall 1 robot per second, until the robots are recalled.
