Our effort is focused on building autonomy into various systems operating in unstructured or uncertain environments. This includes navigating with natural signals without GPS—using the magnetic field, angles to the sun, moon, stars, or landmarks, and gravity for orientation and positioning. Autonomous path and mission planning aim at permitting a few operators to control a large number of assets, such as sensors or unmanned vehicles. Adaptation to changing vehicle conditions needs health monitoring and adaptive control. Our work on energy management aims to balance supply and demand in the smart grid at various levels—in the grid to improve utility efficiency and grid safety, at residences or commercial facilities to reduce their costs and billing uncertainties arising from real time prices—all without operator intervention. Our work on facility security dynamizes security settings in a variety of systems to make it hard for intruders to compromise the system without operators having to monitor very much. We develop and use tools of system identification: static and dynamic, on the sensing systems we construct and the utility and facility data that pass through our controllers. We also use tools of estimation and control of stochastic systems to make sense of the data collected, to convert economic signals to control signals, and to alert human operators.
We work in the field of Biologically Inspired Robots, an emerging multidisciplinary field dedicated to the next generations of robotics that are inspired by nature. We use robotics theories and experiments to investigate the locomotion principles of biological systems (e.g. flying insects, birds, and fish) to decode their secrets of highly maneuverable, stable, and energy efficient movement. These discoveries, in turn, help us develop next generation bio-inspired robots, which can efficiently navigate in air, land, and sea. Such robots can then be used for their greater adaptivity and robustness in performance compared to conventional robots in confined, complex, and unstructured environment.
Our research is at the cross-roads of mechanical engineering and computer sciences driven by geometry and design inspired areas. In particular our core areas are related to machine learning, human-computer natural interaction, computational geometry/modeling, and design. Design as an expression of shapes and manufacture are among our core applications. Our group projects and vision are focused on creating the geometry inspired algorithms for natural creation, reasoning, sensing and response to both virtual and physical artifacts. Our current application areas are inspired by the future we strive to create. We build upon our past successes such as in shape-based search, developing tools for early design, and significant experiences in the making of things.
The Purdue Faboratory researches new and innovative ways to make things. The natural world is filled with soft, robust, and conformable mechanisms capable of stably and safely interacting with their environment. However, the machines and electronics that we build today are most often constructed from rigid components. We build mechanisms that exploit the properties of soft materials, such as extreme deformability and responsiveness to external stimuli. In addition to new soft mechanisms, we also develop new techniques and processes for synthesizing soft composite materials. While many micro-scale manufacturing techniques have been developed for MEMS (rigid, silicon-based) devices, these techniques are not compatible with soft elastomeric and liquid-phase materials. We therefore research new “Soft-MEMS” processes in order to achieve micro-scale soft matter mechanisms. In The Purdue Faboratory, we apply these new processes and devices to the development of soft robotics, wearable robotics, and stretchable electronics.
The IPCL focuses on designing and developing strategies for intelligent and yet high performance control of precision electro-mechanical/hydraulic systems. Current research areas include: Nonlinear adaptive robust control, Energy-saving nonlinear control of electro-hydraulic systems, Intelligent control of precision high-speed linear motor drive systems, machine tools, and piezo-electric actuators for precision manufacturing, Ultra precision control of laser micro-machining processes, Nonlinear control of high-density hard disk drives, Coordinated control of robot manipulators, and Nonlinear observer design and Neural networks for virtual sensing, modeling, fault detection, diagnostics, and adaptive robust fault-tolerant control.
The MSRL performs research on integrated design of "intelligent" components and machines that combines mechanical systems, active materials, electronics and information process capabilities to achieve superior system level performance as well as being able to be interfaced through various network protocols. We are focusing on: (i) integration of smart materials and MEMS (Micro-Electro-Mechanical Systems) into sensors and actuators; (ii) integrating sensory input, information process, and system dynamics to improve system performance and diagnostics; and (iii) utilizing feedback control concept to gain insight into system performance envelope and subsystem interactions to obtain guidelines for design modification. Additional research areas of interest are: Modeling, Control and Diagnostics of Digital Imaging and Printing Systems and Perception Based Engineering (PBE).
The MSRAL performs cutting-edge research on robotic and automation systems at various length scales: macro-scale (cm to m), meso-scale (~100's of um to a few mm's), micro-scale (10's of um to 100's of um), and nano-scale (nm). Research areas of focus are multi-scale robotic manipulation and assembly tasks, mobile micro/nano robotics, bio-nano robotics, mechatronics, robotic system integration, medical robotics and devices, MEMS device design and fabrication to aid in robotics and automation tasks, automation for the life sciences, and micro/nano aerial and ground vehicle design & control.
The Seipel Lab focuses on understanding and designing for the whole-body motion of humans, robots, and the interface between humans and devices. Human movement is important for health, transportation, work, development, and play. Robots are inspired and improved by learning from the way humans and other animals move. Devices that interact with human motion to assist or enhance that motion, such as wearable robots, have the potential to be a transformative future technology.
