In an attempt to reduce exhaust emissions from transportation vehicles, the Taiwanese government plans to enact the "no idling emission" policy regarding motorcycles/scooters. Automatic Idling Stop and Go (AISG) technology is a simple low cost method in which the internal combustion engine is automatically powered off when the scooter stops and restarted when the driver wishes. However, due to dissimilarities between scooters and automobiles in terms of driving behavior and powertrain configuration, the AISG topology and control strategy as used in automobiles cannot be applied to scooters directly. This paper investigated the feasibility of applying the AISG control technique to scooters to enhance the system's security and reliability and address public concerns about AISG by analyzing riding behavior and security issues. The goal of this study was to demonstrate an AISG device, which included the development of a miniaturized AISG control module and control logic algorithm considering operative convenience and safety. Finally the developed AISG control module was installed in a four-stroke, electronic-fuel-injection (EFI) scooter, enabling us to perform an actual on-road test to verify the feasibility and reliability of the AISG control technology.

Compared with the traditional electric-powered wheelchair, people are paying more attention on intelligent wheelchair. While the traditional intelligent wheelchair relays on separate designed control system, it is not good for general use. In that case, ROS provides an easy to use framework for rapid system development so that the researchers can develop various software packages to meet their needs, and we can also call each other packages without considering the compatibility problems. In this paper, we present a ROS (Robot Operating System) based intelligent wheelchair with the function of voice-control navigation. Compared with the traditional navigation, the voice-control navigation is more human. Obviously, ROS increases the versatility of system and reduces the cost. In order to prove the advancement and feasibility of this developed system, some experimental results are given in the paper.

With increasing demand of robot applications in industry or other areas, the development of both reliable and low-cost robot action control system is getting much attention in recent years. This paper has proposed a local closed-loop based robot action control module using independent microprocessors. The robot action commands transmitted from PC via RS232 can be received by the individual authorized microprocessor. There are up to tens of modules to be operated for a variety of robot actions simultaneously and independently. Real world performance results are presented to demonstrate the effectiveness of the proposed approach in term of robust, simple, flexible and efficient performance.
