Noncontact actuation, transmission and manipulation are key factors for compactness, high precision and high speed of the next generation machines. This research aims at the development of basic technologies for noncontact manipulation of small objects using magnets in micromachine applications. An object considered here is a permanent magnet embedded in a microhand and is manipulated by controlling the magnetic field applied to the magnet. We propose mechanisms and controls for noncontact manipulation. First, a mechanism for 2-D magnetically levitated movement is proposed. Second, a mechanism for 3-D magnetically levitated movement is proposed. Results of several experiments are shown to verify the effectiveness of the proposed mechanisms. Finally, design of a microhand which embeds a small permanent magnet is proposed. |
