Abstract:

We describe an aircraft design, which is capable of vertical takeoff and landing and also high-speed cruise on a fixed wing. The aircraft comprises a fuselage with a probe-deployment mechanism, which deploys a sample-gathering probe, located at a front end of the fuselage. A main wing is coupled to a middle section of the fuselage, wherein a right motor and right propeller are coupled to a right side of the main wing, and a left motor and left propeller are coupled to a left side of the main wing. The right and left propellers are angled with respect to the fuselage enabling the aircraft to pitch up to a vertical-takeoff mode and pitch down a horizontal-cruising mode. A pitch motor and pitch propeller are located at the rear end of the fuselage, wherein the pitch propeller is angled to provide substantially vertical thrust to control a pitch of the fuselage.

Abstract:

A passive mechanical system comprising an unpowered exoskeleton to maintain static grip around an object via a tendon drive and ratchet mechanism. The ratchet mechanism combines a passive cable retract and ratchet system with one or more cables acting as artificial tendons. When a user wishes to keep their hand in a specific position around an object, the ratchet system is engaged. A cable retract mechanisim keeps the artifical tendon taught at all times. The combination of these systems allows for the user to keep grip on objects without the need to input force over time thereby reducing fatigue.
