mechanicalengineering programs1,2. It is common for the content of such a course to begin with particledynamics. For such analyses the student need only know the mass of the particle(s) involved;usually given in the problem. The course content progresses to rigid body dynamics. With theintroduction of rigid bodies, an understanding of the distribution of the mass within the body isrequired. Typically, however, that said distribution is again given or is readily determined. As aresult, students tend to view the inertial properties of a body as a trivial input to a mathematicalproblem; similar to the length of a connector or the mass of a component. In reality, determiningthe inertia properties of a real structure can be quite challenging.The project presented

. Through the interaction with remotely accessible realequipment via the GUI, the users should be able to visualize the experimental process, gain afeeling of immersion into a real laboratory environment, and also be able to adjust the input andimmediately observe the experimental output. Usually, the GUI is composed of an instrumentcontrol section, an experimental input section and an experimental results section. In theinstrument control section, the options may include lighting, audio and video and dataacquisition functions. In most real-time setups, a global video view providing an overview and alocal video view zooming in on the analyzed object(s) are streamed in real time. In addition, theusers are often given the option to save the video

advancedconcepts about robotics also will be used in research for graduate students in many applicationsuch surveillance applications. The software will be composed of ten modules. The developedsoftware system allows a mobile robot attached with the robotics arm to navigate in anenvironment autonomously. The mobile robot accepts the commands from the human being(operator) using three different techniques. The mobile robot starts navigating to detect manyobjects based on color(s) and shapes, and also sends these information back to the operatorthroughout Graphical User Interface (GUI). With a camera attached to the mobile robot, thesoftware will be able to classify the objects based on color (s) and shape(s), and to determineits/their position. The

this independence is that work progressed slowly and many codingideas were explored, found to be inadequate, and discarded. The end result of this project wasthat a well-planned and detailed LabView driver was successfully created, but integration intothe rest of the system was not achieved because of lack of time.
