老花眼

老花就是說當你看東西時 必須要用"手"調整焦距 而不是眼睛自動調整 哈哈 最近開始感受到老花的威力 因為看電路板上小小的字已經看不清楚 跳線排珍都會不小心插錯....

Helping robots see with lasers

In order to “see” and respond to its environment as it navigates around a city, says Spletzer, a robot must possess two things: sensors that detect and recognize familiar landmarks and a database with maps that show where those landmarks will be.

Spletzer and his students have taken a cue from Google Street View, which allows Internet users to take virtual tours of distant cities, block by block and building by building, by looking at thousands of stored images. These images are of little use to robots equipped with lasers, says Spletzer, because robots do not see what humans see. But the concept is applicable to the robotic wheelchair.

“To create Google Street View, people drive vehicles around cities, take thousands of images and make maps. We’re making similar maps that are useful for robots, not people. Our robots respond to different cues than humans respond to. Whereas people see the real world and all its details, robots using lasers recognize things like poles and building corners that reduce to a very exact point and are thus easy to track.”

進度報告 - take 4 怪Bug

這兩個星期都一直在找這個怪Bug 就是Slave MCU會自己亂動 原本的設計就算亂動也只會動一點距離 但是卻是轉了好多圈 抓了很久終於抓到 是Master 經由I2C 送 Command出來時 會少送一個Byte

Slave端是知道原因了 可是Master端卻完全不知道為何會這樣 只好先做預防措施 真正的原因還要慢慢查

businesswire iRobot CEO to Outline the Future of Robotics in Healthcare at TEDMED

At the event, Angle will also introduce Tod Loofbourrow, president of iRobot’s newly-created healthcare business unit. The new business unit is committed to exploring the potential of robotics as an assistive technology to promote wellness and enhance quality of life for seniors. In this role, Loofbourrow will be responsible for all aspects of the group’s strategy, research and operations. He will report directly to Angle.

“Hiring Tod to lead our new healthcare business unit underscores the significance of this market opportunity, as well as the commitment the company is making in this space,” said Angle. “Our healthcare mission is to add a million years of independent living to our customers. As the leader in practical robots, we believe that we will have something unique and significant to offer in the field of healthcare.”

iRobot believes that next-generation practical robots have the potential to help caregivers perform critical work and extend the time that people can live independently. Robots may be capable of assisting in senior care in a variety of real-life situations, including household chores and the on-time administration of medication. This could ultimately lower the cost for care.

真正的"印刷"電路板

Xerox's process uses ink containing silver metal that can be used to wire up processing circuitry. It works on surfaces such as plastic that earlier have shown an inconvenient tendency to melt under the high temperature of liquid silver; Xerox's process works with an ink compound with a much lower temperature, the company said.

進度報告 - take 3 - Refactor

Code refactoring is the process of changing a computer program's internal structure without modifying its external functional behavior or existing functionality, in order to improve internal quality attributes of the software. Reasons include to improve code readability, to simplify code structure, to change code to adhere to a given programming paradigm, to improve maintainability, to improve performance, or to improve extensibility.

最近這三個星期 重寫了系統很多Block 事實上10月初時 系統就已經可以運作的有生有色 只是老闆挑三揀四的 只好東改西改 有時候需要改到舊的Code時 就乾脆趁機重寫部分的Code 一方面更新功能一方面增加穩定度 最重要的是 之前急急忙忙寫好的Code 其實都有些不懂硬湊上去的 也在這時候好好的了解一下問題的所在 對系統也比較有信心

幸好我還算靈活 但是改程式對很多工程師來說是件很痛苦的事 對我來說我還覺得蠻有趣的 因為給你一段時間讓你的Code更穩定 到是很不錯的機會

Software Listens for Hints of Depression

It's a common complaint in any communication breakdown: "It's not what you said, it's how you said it." For professor Sandy Pentland and his group at MIT's Media Lab, the tone and pitch of a person's voice, the length and frequency of pauses and speed of speech can reveal much about his or her mood.

最後的Bug - take2

在還未找到最後的Bug時　老闆忽然來關切　希望為了穩定度加上一些功能.....:( 　因此在最後的Bug還沒抓到前　我必須要在多寫一些Bug進去　哈哈　因為　"有改必有錯　有錯就要改" 當然啦也證明沒有最後的Bug這樣的東西　因為還沒找到前你又會寫一堆進去　哈哈哈

Micrium Unveils New Book: uC/OS-III Real-Time Kernel

 
WESTON, FL—September 8, 2009—The author of the definitive text on RTOS technology, MicroC-OS-II The Real-Time Kernel, Jean Labrosse, president and CEO of Micrium has authored a new book, and this one comes with a twist.  uC/OS-III, the Real-Time Kernel covers Micrium’s newest kernel by the same name, and is offered as a two-part book accompanied by an STMicroelectronics STM32F107-based evaluation board  (uC/Eval-STM32F107). The book and board combo target serious programmers and college students who need to understand and create programs based on the timesaving features of a real-time kernel.

Part I of the text covers the internals of the new kernel without going into each detail of the code, as did Labrosse’s previous book. In this version, the emphasis is on the internals, features, API calls, and where and how to use an RTOS, all presented in a clear and useful way, and accompanied by a wealth of diagrams.  Part II provides specific examples for using uC/OS-III on the popular STM32 (Cortex M3) processor architecture.

Debug...最後的Bug

其實是沒有所謂最後一隻Bug 只是當Bug出現的頻率越來越低 以我的系統為例 之前跑不完40Round就會出現Bug (一個Round約30秒) 76Sample 要跑96個Round 到現在跑了很多次測試才會出現一次 越來越不好找出Bug 與程式間的關係 因為關係越來越像Random Output. 當然啦要抓也是可以就是要Log下很多資料然後一筆一筆看 到底問題是發生在哪邊
