Bot:bit

概述

bot:bit人形机器人是一款可以编程控制的人形机器人，支持Mpython图形化编程和Python代码编程，简单易学，通过编程可拓展人的空间思维空间能力。机器人具有多种工作形态，一是装4自由度舵机作为手臂，加上2路电机作为轮子，自由移动的同时双手可灵活操作；二是装有4自由度舵机作为双腿、实现自由行走、避障。

产品特点

动作灵活：全身拥有8个动作关节，拟人造型，实现动作舞蹈，身手灵活。
无线遥控：2.4GHz射频传输模块，可实现遥控格斗运动，欢乐无穷。
内置加速度计
测距避障：内置的高精度超声波模块，能快速返回测量信息、走迷宫、越野的多种任务挑战。
高续航：双节14500锂电池，可循环充电，支持课堂教学应用。

程序下载教程

Step1.m:python编程软件安装：

双击mpythonSetup.exe按提示安装编程程序。进入官网下载（ http://labplus.cn/index.php/product/download )
系统要求：windows7/windows8/windows10，32/64位；windows XP。

Step2.Micro:bit 串口驱动安装：双击mbedWinSerial.exe，按提示安装串口驱动。如需要USB串口打印数据须安装该驱动，不需要可跳过此步骤。

进入官网下载（ http://labplus.cn/index.php/product/download )

Step3.硬件识别：USB接口连接至电脑，打开电源开关。电脑将自动识别到可移动存储设备MICROBIT。

Step4. 程序设计：打开mpython编程软件，根据需要选择图形化编程或python代码编程方式来完成程序。点击软件指令区，选择对应指令进行编程，更方便快速的设计程序。也可点击菜单栏“模块化”，可切换至代码编程。

Step5. 程序完成后，点击，下载程序并保存到microbit可移动盘上，待下载指示灯闪烁完毕后，说明程序下载成功。
