问题描述
我想开始乱搞规划和建设与的东西，但我想不出任何伟大的什么建设思路。你有什么建议吗？
I'd like to start messing around programming and building something with an Arduino board, but I can't think of any great ideas on what to build. Do you have any suggestions?
推荐答案
我告诉孩子们，谁从来没有编程，或者之前的任何电子设备完成的，做一个简单的'Phototrope'，光敏感的机器人，在大约一天。它的成本下包括的Arduino，电子和关闭的，现成的机制£30（英镑）。如果人们真正进入移动机器人，最初的项目可以不断地成长（我觉得是最有趣的一部分）。
I show kids, who have never programmed, or done any electronics before, to make a simple 'Phototrope', a light sensitive robot, in about a day. It costs under £30 (GBP) including Arduino, electronics and off-the-shelf mechanics. If folks really get into mobile robots, the initial project can grow and grow (which I feel is part of the fun).
有需要相对简单的机械的国际机器人大赛上手，例如在英国
There are international robot competitions which require relatively simple mechanics to get started, e.g. in the UK http://www.tic.ac.uk/micromouse/toh.asp
终极性能要求专门建造的机器（明度），但人们会得到可信的结果与一个Arduino纳米，正确的电子产品，和一对夫妇良好的电机。
Ultimate performance require specially built machines (for lightness) , but folks would get creditable results with an Arduino Nano, the right electronics, and a couple of good motors.
以下机器人的行是经典的移动机器人项目。这条赛道可以像电气胶带一样简单。 Pololu对他们近的Arduino机器人3PI一些有趣的视频。该传感器是约1£，并有来自很多地方一堆简单的马达+变速箱包下£10。添加一些£电机控制，你必须自主机器人力学，需要编程！添加红外遥控接收器（约1£），并且您可以使用电视机遥控驾驶它周围。添加一个小的太阳能电池，可以使用一个Arduino模拟输入测量电压，并能找到阳光。随着更多的电子产品，它可以'养活'自己。因此它变得更加复杂。每一步都可能是不超过几个小时到几天的努力越多，你会发现新的问题，解决和借鉴。
A line following robot is the classic mobile robot project. The track can be as simple as electrical tape. Pololu have some fun videos about their near-Arduino 3PI robot. The sensors are about £1, and there are a bunch of simple motor+gearbox kits from lots of places for under £10. Add a few £ for motor control, and you have autonomous robot mechanics, in need of programming! Add an Infrared Remote receiver (about £1), and you can drive it around using your TV remote. Add a small solar cell, use an Arduino analogue input to measure voltage, and it can find the sun. With a bit more electronics, it can 'feed' itself. And so it gets more sophisticated. Each step might be no more than a few hours to a few days effort, and you'll find new problems to solve and learn from.
恕我直言，最有趣的（低成本）比赛的迷宫解决机器人。国际竞争规则要求机器人探索迷宫壁，通常使用红外传感器，并计算出它们的最佳路由。这些挑战包括：跟踪当前位置到近毫米的精度，处理现实世界的联合国predictably嘈杂的环境和优化用最短的距离过弯直线速度。
IMHO, the most interesting (low-cost) competitions are maze solving robots. The international competition rule require the robot to explore a walled maze, usually using Infrared sensors, and calculate their optimal route. The challenges include keeping track of current position to near-millimeter accuracy, dealing with real world's unpredictably noisy environment and optimising straight-line speed with shortest distance cornering.
所有这些方案的16K和1K的RAM，具有实时中断处理（高达某些电机系统100K的中断/秒），传感器采样，电动机速度控制，和迷宫解决是一个有趣的编程挑战。 （您可能使易有计划的32K和2K RAM： - ）
All that in 16K of program, and 1K RAM, with real-time interrupt handling (as much as 100K interrupts/second for some motor systems), sensor sampling, motor speed control, and maze solving is an interesting programming challenge. (You might make it 'easy' with 32K of program, and 2K RAM :-)
我工作的一个'约束'机器人挑战（基于Arduino的），使机器人的性能主要是对编程，而不是一个大的预算。
I'm working on a 'constrained' robot challenge (based on Arduino) so that robot performance is mainly about programming rather than having a big budget.
