A novel design to biochip microarray instrument is use of linear motors, in preference to conventional rotary motors driving ball screw. Three ironless core linear servo motors direct drive the X, Y and Z-axis motion, Improve performance such as superior positioning accuracy, high-speed operation and increased efficiency. The whole configuration for new microarray printing instrument is designed. Furthermore, the structure of special linear motors is also designed detailedly. And the linear servo motor automation control technology is introduced in this paper.

PurposeModern day manufacturing has seen the replacement of manual transfer of parts between press machines with automatic transfer systems. Higher automation productivity demands greater flexibility of transfer devices. This paper deals with methods to improve the flexibility of fixtures designed to transfer parts between press machines.Design/methodology/approachDescribes methods to improve the flexibility of fixtures designed to transfer parts between press machines in Press Shop 3 at Iran Khodro Company (IKCO). A fuzzy C means clustering‐based method is developed to optimize the number and arrangement of actuators for each fixture. Economical aspects of this novel design are addressed as well.FindingsThe simulation results suggest that application of a flexible fixtures system and use of linear motors was the best method of adding flexibility to the loader‐unloader system.Originality/valueProvides evidence that flexible components are indispensable to increasing production speed and reliability in an automated system.

Novel Design

Passive variable stiffness at the human hand joints is shown to be critical for achieving stable and dexterous grasping and manipulation. Our long-term goal is to implement it in robotic hand joints. We introduce a novel design, using linear springs and non-circular cam, for a variable stiffness joint mechanism that mimics the passive stiffness characteristics of human hand joints. We present a methodology based on the principle of virtual work for synthesizing the cam shape in the joint. Key innovations of our design are a) human-like joint stiffness profile, b) large joint range of motion, and c) modular arrangement for varying torque range. We have built a prototype for validating our approach and the experimental results demonstrate that the proposed joint mechanism fulfills the design goals of our study.
