Personal roboport

Overview
The 
Each equipped 
- Each
Personal roboport adds 10 active robots and 2 charging ports.
- The internal energy buffer holds 35 MJ, which is close to the capacity of two Personal batteries.
- If a personal robot runs out of energy, it slows down but continues trying to catch up with the player.
- The total activation range for N equipped Personal roboports is calculated as
sqrt(N × 30 × 30)and then rounded to the nearest integer.
The scaling of the activation area increases gradually as more units are equipped: 1 gives 10 robots and a 30×30 area, 2 gives 20 robots and a 42×42 area, 3 gives 30 robots and a 52×52 area, 4 gives 40 robots and a 60×60 area, 5 gives 50 robots and a 67×67 area, 6 gives 60 robots and a 73×73 area, 7 gives 70 robots and a 79×79 area, 8 gives 80 robots and an 85×85 area, and 9 gives 90 robots and a 90×90 area.
