A ZONE - or Orbital Exercise Zone - is an item of technology used by Machine Robo Rescue. Designed as an area for Machine Robo to train in safety, it is also be used to contain threats during emergencies since the emergence of the Disasters. Each Leader Robo can create a ZONE at any time. While a ZONE can absorb considerable damage they are not indestructible, and there are limitations to the technology. Only MRR reinforcements can enter the ZONE once it is activated.
Four types of ZONE are used:

- The 'rules' for deploying a ZONE in the show are not always consistent; there are several occasions when projecting one might have helped a situation (for a random example, catching Laura in "Emergency! Enter Battalion") and it's let slide for plot purposes.
- Which ZONE is called up seems to be random.
