Novel Hopping Mechanism Using Permanent Magnets for Tiny Asteroid Exploration Rover
This paper presents the novel hopping mechanism using permanent magnets for tiny asteroid exploration rovers. The main part of the mechanism consists of one movable magnet and two stationary magnets. The mechanism uses for hopping the impact force generated when the movable magnet sticks to the stationary magnet. The features of the mechanism are that the large impact force can be generated in ...
متن کاملFirst Ever Storage of Ultracold Neutrons in a Magnetic Trap Made of Permanent Magnets
Further improvement in the accuracy of any neutron lifetime experiment by means of ultracold neutrons (UCN) in material bottles is limited due to unavoidable systematic effects when the UCN are reflected from the walls. However, such effects can be excluded in principle if magnetic trapping of UCN is used. The storage of UCN in a small magnetic trap made of permanent magnets was demonstrated fo...

متن کاملA Tiny Specification Metalanguage
A logic programming language with potential software engineering benefit is described. The language is intended as a specification language where the user specifies software functionality while ignoring efficiency. The goals of the language are: (1) a pure specification language – “what, not how”, (2) small size, and (3) a metalanguage – able to imitate and thus subsume other languages. The lan...
متن کاملA MEMS implementation of a Brownian Ratchet
A Brownian Ratchet is a device that can rectify the random Brownian motion of particles to yield a directed steady-state flow. We can imagine a thermo-fluid field of particles which interact with the ratchet. The laws of thermodynamics imply that the ratchet must use energy from some other source. The dynamics of continuous-time Brownian ratchets are determined by a stochastic partial different...
