How it Works?

Project baseline data is loaded on to Surface

Field Data is sent from TMB Prism to Station

Station analyzes data and sends to Control La

Control Laptop processes data and presents toperator via the Virtual Laser target board

Operators make adjustments if necessary Positions are sent in real time to project mana

How it Works?

Pipe Information is uploaded to onboard pc

Robot is lowered into network via a manhole o

Assessment of pipe is executed

Robot is retrieved at the end of survey point (D

points) Data is collected and analyzed.
