Laboratory for Industrial Metrology and Automation

Welcome to the Laboratory for Industrial Metrology and Automation (LIMA), a home for assistance and consulting in the focus area of industrial application of measurement and instrumentation.

Mission Statement:
LIMA aspires to educate students in science and engineering to become leaders in research, academia and in industry. This way, they can contribute to the wealth creation of the nation as well as to humankind in the 21st century and beyond.
Located within the College of Engineering, we at LIMA nurture future leaders in innovation in science and engineering. We provide young students with systematic and in-depth education in advanced engineering concepts based on achievement and creation of wealth for humankind.
LIMA educates students towards multidisciplinary thinking to facilitate the solution of complex problems, and to drive novel research discoveries and transformational learning. Our multidisciplinary education integrates various existing academic disciplines, and it leads to develop new areas through the application of a system that is more flexible.

Research Activities:
Our research include both basic and applied research. At LIMA, we direct our research efforts to:

Measurement, instrumentation and control in industry (Industrial Metrology), is a rapidly growing area driven by the capabilities of instrument technology, by the development of other technologies, and by social and economic demands. Most areas of technology rely to a substantial extent on instrumentation and could not function effectively without it. Instrumentation is the key enabler of modern manufacturing, through automation, which enhances productivity and ensures consistent quality. The demand for improved and assured quality means ever better instrumentation.  An important growing point is the integration of sensors, information processing, actuators, and control systems into products such as robots. These are not only significantly applied in mechanical manufacture, but also in such operations as building and laboratory automation, and in medicine and surgery.  There is also the importance of instrumentation in care for the environment. Monitoring of pollution ranging from the analysis of noxious chemicals to the measurement of noise and the remote sensing from space are leading areas of application. In all these areas there are great demands and opportunities for innovative development and innovative application of instrumentation technology.
LIMA provides state of the art manufacturing, engineering, and quality services to companies, exposes undergraduate and graduate students to an exciting amalgam of technologies by way of   incorporating measurement and instrumentation into secondary education with the objective of further engaging students through an exciting application of math, science and computers, and also serves as the nursery for industry and the national laboratories.


Current Projects:

Patients with diabetes mellitus and peripheral neuropathy develop loss of neural sensory feedback as the neuropathy progresses. As a consequence of the progressive disease process, diabetic foot pressure ulcers develop which in turn leads to the development of what infections and eventually amputations. This research aims at developing an ectopic sensory center that can substitute for the loss of proprioception on the foot.

This research aims to develop a computational intelligence methodology driven by a wearable microelectromechanical systems-based (MEMS) sensor array for efficient and reliable analysis of human gait dynamics at a level capable of quantifying variations from morphometrically adjusted normal in three dimensions and real-time. This is an essential and limiting step in the conceptualization of new systems for objective characterization of gait disability and recovery with the potential for rehabilitative and compensatory interventions modulated by immediate and case-specific kinematic feedback.

The angular positions of the body’s segments with respect to space and relative
to each other play an important role in understanding human dynamic behavior in
 space. This behavior is very complex and involves many physical, perceptual
and motor aspects. The position sense of a limb involves not only spindle
receptors in the muscles, but also receptors in the skin and in the capsules of the
joints. When tested with psychophysical means, one finds that the brain
combines these many signals into a rather accurate position sense over a broad
dynamic range (true with the small angles used here). This sensor for the reliable
measurement of joint angles provides measurements of the joint angles in 3D

This device will control balance and posture in the human, i.e. equilibrium position, using the principles of machine intelligence quotient, MIQ. This device exhibits the characteristics of the human neuromusculoskeletal system.

Exoskeletal device to mimic the human movement, and in the case of the hip-joint connection. The device is a lower extremity hip-joint gait device that emulates, follows and gives motion to all the possible movements of the legs by using a ball joint concentric to the head of the human femur, by having a partial spherical shell surrounded by an internal and an external spherical plates, that allows the shell to rotate around three axes. Control of a prototype synergistic multi-axis robotic system
 The main objective of this project is to develop a mechatronic device for the efficient assessment of balance and posture. This device may be used for the treatment of diseases associated with balance and posture disorders. It may also be used for training in different areas like sports, in the military and in space exploration (astronauts).
 This research project exhibits high significance for multidisciplinary research. It includes and requires a high level of engineering concepts from areas including but not limited to electrical and mechanical engineering, control engineering, biomedical engineering, computer Science and industrial design (ergonomics).

This project is the development of a medical robot for the purpose of rehabilitation and the assessment of the disabled upper extremity. In this project, the motors are made responsible to move the robotic manipuladum according to the user command by programming the servo drives. The user’s (patient or normal subject) muscle activity, elbow flexion and extension angle, and the accelerations are recorded in three modes of movement by the user:

The data which is collected from both patients and normal subjects are compared to assess the level of impairment in patients in accordance with the normal subjects. Additionally, the robotic manipulandum can also be used as a rehabilitator, as the repetitive movements and the reaching tasks can be achieved using this medical robot.
