GuardBot

The GuardBot is an invention by Apex. It is a spherical machine capable of all-terrain movement at high speeds. Equipped with cameras and at times SMGs, the GuardBots are primarily used as sentry units that are on constant patrol throughout Erie, Pennsylvania. Most appear to be unarmed and will often stop random passerbies to identify themselves. Guardbots guarding entry into buildings will ask for identification and purpose for visiting. If an unarmed Guardbot sees a threat, it will sound an alarm from its unit and maintain distance while transmitting its location and the threat's location until the larger and armed GuardBots arrive with the walking sentries.

Guardbots are capable of traversing all terrain aside from air, this includes water, gravel, asphalt, grass, sand, etc.
