The single port has to have snake like robotic arms because otherwise it can not be maneuvered inside the body.
Titan can easily put together multi ports that are snakes meaning that the arms would have many many joints like their single port.
The snake robots are harder to design and control and that is why few have tried it. Titan can produce a multi port with each port having a snake. It would be a subset and not a superset of what they have already done.
