A grasping mandible, also referred to as a grasper jaw or grasping jaw, represented a component utilized in droid construction. These mandibles were frequently incorporated into the design of the F1 exploration droid. Reflecting its design inspiration from canine species, this droid possessed a grasping jaw situated within its head structure. This jaw was engineered to securely grip items without causing damage, enabling the droid to employ it for relocating injured scouts away from hazardous situations. The inclusion of the grasper jaw, in conjunction with the droid's comprehensive sensor suite, restricted the F1's verbal communication capabilities, limiting it to a restricted spectrum of alert signals. The E3 Companion Droid also included a grasper jaw in its design.
