Collaborative Robots (Cobots)
Cobots are designed to work safely alongside human operators without cages or barriers. In aerospace, they assist with lighter, more intricate tasks where human dexterity is still valuable, but a robotic arm can provide consistent support or perform repetitive actions. For example, a cobot might hold a component in place while a human worker fastens it, or apply sealant in precise patterns. They enhance productivity by freeing human workers from mundane tasks, allowing for a more symbiotic human-robot interaction.
Mobile Robots and AGVs (Automated Guided Vehicles)
To support the flow of materials and tooling across sprawling aerospace factories, mobile robots and AGVs are critical.
