In E-experiments, the network servers often used to manage experimental plants centrally require high power consumption. In order to reduce such power consumption, cost and size, this paper presents a portable embedded web controller (PEWC) combining embedded technology with Linux + Apache + MySQL + PHP (LAMP), which is the solution stack most widely used globally in Web development. Instead of using servers, the PEWC is used to build a distributed E-experiment system that enables users to do remote control through web pages online. Experimental results show that this system successfully controls robot-arm systems remotely and reduces power consumption by 99%, cost by 90% and size by 95%.
