Propulsion: This part of the machine’s systems is


crucial to getting the machine moving forward. The system involves the use of gripper plates, on the surface of the machine, which push against the surrounding ground; they are pulled backwards and then rearranged in continuous repetition of the process to deliver forward movement. Support systems: To initiate the boring process, a


starting platform is placed on the surface or in an excavated pit – dependent on what the user needs. The platform into which the machine is inserted can be adjusted for the desired angle to start tunneling into various directions. Also placed outside but connected with the machine in the underground, her sensors,


and actuators – the software continuously monitors, analyzes, and controls the machine’s actions as well as status from the surface.


DRIVING AHEAD The subsystems’ capabilities, the fact that they already have worked individually and as an integrative overall system, and winning the innovation-driven international competition, now gives Swissloop Tunneling confidence that it is on the right track and can fruitfully pursue technological development. The team is planning the next steps to achieve the


longer-term vision. Thus, the project now needs to identify where further optimization is necessary and
