What “Lab Experiments”?
Controls systems stations -- 6 systems
Chemical engineering -- 9 systems
Mechanical engineering -- 5 systems
What is "on the Web"?
REAL lab experiments, offered via the WEB
--Experimental design--Operation of equipment--Retrieval of data
What is "All the Time"?
Just what it says
Accommodates Scheduling ProblemsAllows additional experimentationWe enjoy doing this stuff

Vision & Plans
Expanded learning opportunities
RemoteEngineering
AsynchronousLaboratories
University Partners Industry Partners
Vision & Plans
-- Students will have access
to on-line labs with a
variety of experimental systems
in chemical and
mechanical engineering
Vision & Plans
-- Students will be able
to easily design and conduct experiments
from home, dorm, computer lab or office
-- Students will be able to compare
local lab experimental results
with on-line lab results
Vision & Plans
-- Faculty will have materials
to implement remote laboratory
experiments in their own institutions
-- Faculty will have
more diverse laboratory offerings
-- Faculty will be able to easily use
on-line labs in classroom demonstrations
