Impact of Telecommunications

Variation in Configuration

of Communication

Option 1 – fibre optic communication

Option 2 – fibvre-optic & back-up (satellite or cellular)

System Response

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
