Autonomous 4 Axis Planar Manipulator Robot for Grapping stuff at offline market.
This is made of gradient based path-planning and Odometry using matlab bluetooth communication and arduino spi internal communication
This document discusses game-based learning and the concept of "flow" in learning. It argues that games can engage students by providing clear goals, feedback, and an optimal balance of challenge and skills. When immersed in a game, students experience "flow", a state of focused concentration and enjoyment where their perception of time is altered. The document suggests educators should design learning environments that incorporate elements of games and flow to increase student engagement and learning outcomes.

The document provides information on selling a home, focusing on the four key factors that determine when and how quickly a home will sell: price, condition, location, and marketing effort. It discusses how to properly price a home, prepare it for showing, leverage online marketing and technology, and implement a comprehensive 12-point marketing program to effectively sell the home. Pricing the home correctly from the start and making minor repairs to improve its condition are emphasized as important tactics to sell faster and for the best price.
This document provides a summary of the real estate market in July 2009. It notes that home sales and prices have increased for four months while inventory has decreased, signaling a recovery. However, tight credit availability remains a challenge. The economy appears to be slowly improving, though unemployment and interest rates could impact the recovery. Recent government actions include expanding loan modification programs and FHA capacity to support the market.
The document outlines a framework project and several local projects. The framework project aims to address a main problem through objectives and a strategy. It supports and coordinates multiple local projects through actions like mapping and communication. Each local project is situated within a context and problem, with its own objectives, vision, and activities to achieve results. Design played an implicit or explicit role in the projects, utilizing tools like specific methodologies.
Is A Difference In Scale A Difference In Kind?Dan Klyn
The document appears to be a collection of images, text snippets, and diagrams on the topic of structural design vocabularies and conceptual frameworks. It includes examples of vocabularies proposed by Venturi and Scott Brown, Hobbs, and contextual elements like balconies and silos. Key concepts discussed are integral ornament, decorated sheds, spatial grammar, geometric primitives, and learning from precedents like ducks and sheds. The document serves to illustrate different approaches to categorizing and understanding structural design options and strategies.
This document summarizes Dan Klyn's presentation at #IXDAPDX on places made from information. It discusses how information can be used to create places and the key elements that define a place, including firmness, commodity, and delight, which are derived from Vitruvius' triad of firmitatis, utilitatis, and venustatis. The document encourages the audience to apply these concepts when evaluating if something has become a place and to balance these elements in their work.
The document discusses the wet tropics climate and proper equipment. It notes temperatures range from 26C to 32C with highest in late spring/early summer after rain. Summers are uncomfortable due to high heat and humidity with an average annual rainfall of 150 inches. Proper equipment includes a backpack, loose light clothes, hat, sunglasses, extra socks, boots, bug spray, sun protection, water bottles, and a first aid kit. Bodily systems like respiratory, nervous and circulatory can be affected by the heat and humidity through difficulties breathing, slowed reactions, and potential heart failures.
11. 从scull看驱动设计
驱动程序的机制设计——提供用户程序接口
scull驱动实现的设备
– scull0 – scull3 : each consisting of a memory
area that is both global and persistent
– scullpipe0 – scullpipe3 : FIFO devices, work like
pipes
– scullsingle : allow only one process to use at a
time

12. 从scull看驱动设计
scull驱动实现的设备
– scullpriv : private to each virtual console,
different memory area assigned
– sculluid/scullwuid : can be opened multiple times,
but only by one user at a time.

13. 设备的Major number 和 Minor number
Major number : identifies the driver
associated with the device
Minor number : used by the kernel to
determine exactly which device is being
referred to.
Linux 内核使用dev_t类型来表示major
number(12 bits)和minor number(20
bits)

14. Device Number 的分配和释放
使用register_chrdev_region函数来获得指定的
register_chrdev_region
Device Number
– 需确定指定的Device Number尚未被占用,否则出错
使用alloc_chrdev_region函数来从内核获得一个当
alloc_chrdev_region
前可用的Device Number
使用unregister_chrdev_region来释放当前被占用
unregister_chrdev_region
的Device Number
