The SP2526A device is a dual +3.0V to +5.5V USB Supervisory Power Control Switch ideal for self-powered and bus-powered Universal Serial Bus (USB) applications. Each switch has low on-resistance (110mΩ typical) and can supply 500mA minimum. The fault currents are limited to 1.0A typical and the flag output pin for each switch is available to indicate fault conditions to the USB controller. The thermal shutdown feature will prevent damage to the device when subjected to excessive current loads. The undervoltage lockout feature will ensure that the device will remain off unless there is a valid input voltage present.

智能機器人硬件功能模塊介紹1.核心控制板：raspberry b+（樹莓派B+）：一種卡片式電腦。樹莓派是只有信用卡大小的卡片式電腦，其系統基于Linux。截止至2012年6月1日，樹莓派只有A和B兩個型號，主要區別：A型：1個USB、無有線網絡接口、功率2.5W,500mA、256MB RAM；B型：2個USB、支持有線網絡、功率3.5W，700mA、512MB RAM。2.底層電路驅動芯片：Arduino 。Mega2560的處理器核心是ATmega2560，同時具有54路數字輸入/輸出口（其中16路可作為PWM輸出），16路模擬輸入，4路UART接口，一個16MHz晶體振蕩器，一個USB口，一個電源插座，一個ICSP header和一個復位按鈕。Arduino Mega2560也能兼容為Arduino UNO設計的擴展板。3.底層硬件：驅動電路、控制電路 包括（ln298、hc-06藍牙模塊、舵機、攝像頭、麥克風、無線網卡、電機、地盤、傳感器若干、材料等） 4.工作原理：樹莓派用來處理上層指令、運用大型代碼、和代碼整合等，例如：人臉識別、語音識別、郵件發送、環境數據上傳到互聯網、獲取網絡指令等。通過串口通訊和底層驅動芯片arduino進行交互，和數據傳輸。arduino則負責底層電路的驅動、環境檢測、快速機動、預報處理等工作1.該項目中我們自主研發了一套無線充電設備，最大的轉換效率可以達到40%，安裝在機器人的底端，可以實現機器人長時間的工作而不需要人為去充電，解決了用戶不在家機器人也能正常工作的問題。該項目已經獲得了專利。
