Real-Time Experiments Merged Online for Tomorrow's Engineers (R.E.M.O.T.E.)

Enhance conceptualization and use of fundamentals through multiple means of visualizationIncrease participation through improved dissemination, accessibility, and availability of experiments via the Internet to students at many institutionsEngage students collaboratively to improve understanding of system dynamics

Motivation for R.E.M.O.T.E.

Large experimental setups are expensive –resource sharing between campusesStudents need access on an individual basis, instead of demonstrations to large groupsStudent difficulty with conceptualizing and visualizing System Dynamics concepts

Motivation: Online Virtual Controller PrototypingUsers can specify initial condition, controller parameters, and generate animated responses to prototype their controller designs.

ImplicationsExperiments were made to be run by people not machine. The lab setup requires a form of reset.Simulation and Virtualization is not Real, nor can it be in Real-Time. Therefore we need live streams of data.Software collaboration (Data Exchange)

Data archiving is available but yet is not very portable. Size student group and time of day constrictions.Administration and security

Current ProgressWinPcap failed to support enumeration of the Loopback device.Hooking is one of the other alternatives.TCP/IP is still considered feasible.

Overall strong outlook in finding a solution in data sharing.Still challenged, however.

Progress: Camera control and streaming

Remote control of the camera is ready to be used by administrators.Programming done in assembly and C by a third-party. PHP will be the gateway between the commands to the program made and the camera.The camera is streamed by demand.
