In this project, a modified Delta parallel robot is designed in which the number of passive joints is reduced, and an active joint is added to the hardware. To the best of our knowledge, this configuration seems to be the first of its kind.
In this project, kinematic and dynamic analyses will be performed. Active compliance control and collision anticipation algorithms will also be developed for this new design. This configuration will be used as the “waist” of an omni-directional, self-balancing service robot. Methodology and novelty of approach and/or application
Robot-assisted minimally invasive surgery is an emerging field in research and industry. A major challenge with the existing medical robotic systems (including the da Vinci® from Intuitive Surgical) is the lack of haptic feedback (sense of touch). On the other hand, medical imaging is only used for direct visualization in the existing systems. Certain surgical sub-tasks (such as simple cuts, cleaning and suction, etc.) can be automated using imaging feedback and visual serving to assist surgeons during the operation.
Wireless communication devices have become an essential part of our lives and new ubiquitous applications are evolving rapidly. The spectrum of wireless links is limited and its efficient utilization via smart technology is very crucial to fulfill the ever increasing demand. Femtocell using a low-power home base station is a promising technique for serving indoor quasi-immobile users. It has the potential to provide better coverage and increased data rate to indoor users and to support more users/services by offloading the major traffic from the macrocell to the underlay femtocells.
Free Surface Electrospinning (FSE) is a novel process capable of producing non-woven webs of continuous nanofibres with controlled morphology and size from polymer solutions with the application of high electric fields. This novel scheme which was based on a rotating cylinder-solution feeding system is capable of producing nanofibres at a reasonable rate with compared to the conventional capillary schemes. We propose to further investigate and optimize the scheme for the use of wide range of applications in industry.
As data transmission rates increase, transmission quality over existing channels degrades. Advanced signal processing techniques to compensate for the mechanisms which degrade transmission quality are known. Simulations studies conducted at the data rates proposed for next generation data communication products show that pre-cursor inter-symbol interference (ISI) is becoming a significant contributor to degradation in transmission quality.
Location information is an important enabler for context-aware services and communication system improvement. Localization can be performed by comparing the power readings of all surrounding wireless transmitters to a database of these readings at all possible locations, known as the radio map. For this localization process to work, the system requires accurate radio maps. Our industrial partner, Siradel, have designed a software to create modeled estimates of radio maps for any site, which need to be refined with measurements.
In general, if a user is not willing/able to implement himself the solution, attaching sensor and actuator equipment to a computer typically leads to disproportionately expensive purchases of proprietary hardware or software, which often still requires a considerable time investment. The goal of our planned company is to provide affordable computer-attached electronic equipment to individuals and businesses worldwide. Our devices will: (1) perform data acquisition and control of external hardware, i.e. input/output (I/O) operations; or (2) speed-up compute-intensive calculations.
The ever growing market demands for higher data rates and more reliable communication are the main drivers behind the technological growth in the wireless telecommunications industry. This R&D project aims to address an innovative technological shift from conventional wireless cellular networks to a paradigm of cooperative cellular networks that can potentially provide multiple-fold improvements in terms of the total data rates.
Pulse shaping devices are the key elements for optical signal processing that are capable of reshaping the temporal waveform of optical pulses. The applications of pulse shaping devices include ultrahigh-speed optical telecommunication, ultrafast all-optical computing and information processing, biomedical imaging, and electronic and photonic signal/device characterization and monitoring. For these applications, ultrafast optical waveform shapers capable of synthesizing temporal waveform features down to the sub-picosecond regime are required.
