要看蹦极还是要听音乐? 大屏幕上出现了两种选择。只见3000多个来自世界各地的IBM软件合作伙伴每人手拿大型遥控器,对准大屏幕几乎同时按动,不到1秒钟结果出来了,大部分人要看蹦极。哇,有位先生快速爬到15米高处勇敢地跳了下来……这是8月中旬美国拉斯维加斯举行的IBM Solution 2000大会开幕式,表现了在合作伙伴中再生的主题。凭什么选择IBM免费“午餐”大会上发布了alphaworks的6种开发工具,这些开发工具针对Java、Linux、 相似文献

在当前如火如荼的SOA运动中,SOA的业务价值和架构方法成了所有人关注的焦点,而安全则被有意或无意的忽略。但是如果没有对安全的充分重视,SOA不仅解决不了现实的问题,反而会引起更大的麻烦。 相似文献

The purpose of this research was to make a jumping machine jump over a big obstacle or a ditch. We plan to do fundamental research to (1) make the jumping machine jump as high as possible, (2) control the direction of the jumping, (3) control the attitude of the machine in the air, and (4) make it land softly. In this paper the method of making the jumping machine land softly is described. The optimum soft landing of the jumping machine is defined as follows: ? First, the impulse which the jumping machine receives from the ground should be minimized. ? Second, the maximum force which it receives from the ground should be minimized. We apply this test to the jumping machine when it lands and test the validity of the soft landing by experiment. 相似文献

This study aims to improve human jumping capabilities from an engineering perspective by proposing a supportive device, as
in a robot suit. The robot expresses a time-oriented optimal torque pattern, which is the most efficient jumping motion and
timing, of each joint that can jump the highest using a motor. Then humans learn the most efficient jumping motion. To actualize
the most efficient jumping motion, we observe human jumping motions and analytically calculate the most efficient torque patterns
based on them.

A biped robot, MARI-3, for jumping is developed, of which the ultimate objective is fast walking and running. Its mechanical structure including the joint configuration and specification, the knee joint, and the speed reduction mechanism are described in detail. A specific control system RON (RObot Network) for MARI-3 that is a serial and distributed network and consists of a microcontroller, host unit, servo units, sensor units and servo amplifiers is presented as well as the sensor system. With the developed biped robot MARI-3, one-leg jumping of 110 ms jumping time and 4.0 cm jumping height was implemented as initiative and verification experiments. Furthermore, by comparison of MARI-3 with other jumping or running robots, MARI-3's potential ability for fast walking, jumping and running becomes clear. 相似文献
