Design of direct-drive mechanical arms
This paper describes the design concept of a new robot based on the direct-'drive method using rare-earth DC torque motors. Because these motors have high torque, light weight and compact size, we can construct robots with far better performance than those presently available. For example, we can eliminate all the transmission mechanisms between the motors and their loads, such as reducers and ...
متن کاملScaling of Direct Drive Robot Arms
This paper studies the ways that the performance of direct drive serial robots changes as system size is changed. We are particularly interested in the physical laws for scaling down direct drive arms to small sizes. Using theoretical scaling analysis, we show that there is a net physical performance advantage to small direct drive arms. A key factor for direct drive robot performance is the to...
متن کاملComparative Structural Analysis of 2-DOF Semi-Direct Drive Linkages for Robot Arms
| This paper reports the rst direct structural comparison of a family of 2-DOF semi-direct drive linkages for robot arms. One novel and three previously reported linkage designs were optimized and compared using niteelement analysis. The results quantify structural properties of the four optimized designs under variations in joint position and payload. Several frequently overlooked issues essen...
متن کاملMechanical cloak design by direct lattice transformation.
Spatial coordinate transformations have helped simplifying mathematical issues and solving complex boundary-value problems in physics for decades already. More recently, material-parameter transformations have also become an intuitive and powerful engineering tool for designing inhomogeneous and anisotropic material distributions that perform wanted functions, e.g., invisibility cloaking. A nec...
متن کاملBasic Principles of Direct-Drive Ignition Target Design
LLE Review, Volume 106 83 Introduction Inertial confinement fusion (ICF) is an approach to fusion that relies on the inertia of the fuel mass to provide confinement. The confined fuel must reach a high temperature and density to produce enough D + T $ a(3.5 MeV) + n(14.1 MeV) reactions so that the total energy released is much larger than the driver energy required to compress the fuel. The cap...
