Variation in Configuration
of Communication
Option 1 – fibre optic communication
Option 2 – fibvre-optic & back-up (satellite or cellular)

Model Predictive Control
1. Observe the state of the network
2. Devise sequence of moves of multiple manipulators
• Respect the constraints
• Aim towards the objective
3. Implement the first move of the optimal sequence
4. Wait for the network to respond
5. Go back to Step 1
