Raspberry Pi is a credit card sized Linux computer based on ARM11 architecture.Because of its small size,low power consumption and powerful performance,a robot controller is a suitable role for it to play.As a robot with artificial intelligence,speech recognition for controlling the robot and voice feedback to users is key parts of the entire system.In this essay,a robot called Lisa is assembled,and a speech control and interactive system is implemented based on Google voice API which is a voice recognition engine provided as a cloud service.In order to analysis complex voice commands,a semantic method is developed to catch key words from command sentences.Then try to make a pattern match between key words and instruction set build-in the robot control system.The speech recognition control and interactive system is effective and well behaved after experimental verification.

Dexterous robotic hands are changing the way robots and humans interact and use common tools. Unfortunately, the complexity of the joints and actuations drive up the manufacturing cost. Some cutting edge and commercially available rapid prototyping machines now have the ability to print multiple materials and even combine these materials in the same job. A 3D model of a robotic hand was designed using Creo Parametric 2.0. Combining "hard" and "soft" materials, the model was printed on the Object Connex350 3D printer with the purpose of resembling as much as possible the human appearance and mobility of a real hand while needing no assembly. After printing the prototype, strings where installed as actuators to test mobility. Based on printing materials, the manufacturing cost of the hand was $167, significantly lower than other robotic hands without the actuators since they have more complex assembly processes.

The problem: Understanding intent is a critical aspect of communication among people and for many biological systems. While people are very good at recognizing intentions, endowing an autonomous system (robot or simulated agent) with similar skills is a more complex problem, which has not been sufficiently addressed in the field. The issue of intent recognition is particularly important in situations that involve collaboration among multiple agents or assessment of potential threats. In the former case collaboration can be greatly enhanced, while in the latter case dangerous situations can be detected before any harmful actions can be finalized. In this project, we propose to develop methodologies for intent understanding, with specific focus on autonomous systems for naval and collaborative robotics applications. The main research problems we will address in this project are to: (1) develop tools for understanding the high-level intentions of groups of agents, (2) develop algorithms for intent understanding based on contextual information, (3) develop vision-based techniques for learning of contextual information, and detection and identification of objects of interest.

To further improve the accuracy of SAR image segmentation in the marine spill oil detection,a segmentation method of marine spill oil images based on Gabor,Krawtchouk moments and KFCM is proposed in this paper.Firstly,the marine spill oil image is decomposed by Gabor transform to obtain the texture features of image.Then,the Krawtchouk moments are applied to extract the shape features of image.Finally,the image segmentation is achieved based on KFCM.A large number of experimental results show that,compared with the related segmentation methods such as Tsallis entropy threshold method,CV model method and the method based on Gabor,Krawtchouk moments and FCM,the proposed method can achieve better result.

Withdrawal from these drugs is generally so intense that those who are dependent upon them continue taking the drugs in increasing dosages to avoid withdrawal or to maintain the high produced by the drugs. Withdrawal symptoms may begin within 6 hours after the last heroin usage and may last for up to several months. An effective treatment for opioid dependence and addiction includes medication-assisted therapy with the opioid medications methadone or buprenorphine, the only two opioids federally approved for the treatment of these conditions. Methadone relieves cravings, blocks the euphoric effects associated with heroin and other opioids, and prevents withdrawal. Buprenorphine aids in treatment by preventing symptoms of withdrawal.

The system which could be described as "trinity,seven subsystems" has realized automatic remote control of the machine working process with orientation,localization and formalization.At local place,it realized automatic position and pose online detection,automatic orientation tunneling,automatic section cutting and forming and adaptive control of cutting arm swaying speed,it was the first time that realized absolute measuring of roadheader frame position and pose error under coal mine working condition in our country which could avoid error accumulation in relative measuring and guarantee the high precision of orientation tunneling.In underground remote,it realized remote monitoring,wireless remote control and video surveillance,thus realized remote control with multiple angles,visualization and one-button control under the condition of dustiness and vibration.At any network access point on ground using mining ring network,it realized real-time monitoring and displaying of roadheader running state parameters,and realized the functions of remote fault diagnosis and alarming.The whole system has been tested many times underground.The application results show that it is stable and reliable.With the development of automation,intellectualization,and informatization and other high technology,this system will be more and more suitable for fully mechanized excavation face.

The increase in the older population as well as its increased frailty has led the National Highway Traffic Safety Administration (NHTSA) to conduct research initiatives examining the safety and mobility of older adults. Although older adults are struck less frequently than children, they are more likely to die after being struck due to frailty or physical complications. With that in mind, NHTSA is interested in developing effective countermeasure strategies that can be strategically targeted towards the prevention and mitigation of crashes involving older pedestrians. The objective of this project was to identify appropriate countermeasures that will reduce older pedestrians exposure to injuries and fatal crashes. This involved exploring countermeasures within the area of transportation as well as in other fields such as public health and education with the intention of identifying strategies that can be implemented to increase older pedestrian safety. Additionally, experts in the fields of aging, occupational therapy, transportation safety, traffic engineering, aging and ophthalmology, gerontology, and older pedestrian safety were contacted. These individuals provided contextual information to help explain the dynamics behind older adults involvement in pedestrian crashes as well as insights into what strategies might be effective in communicating with older adults to effect change in their walking behavior. This background research was intended to identify strategies used in disseminating information to older populations as well as strategies used to effect change in the behavior of older adults. This report is a review of key literature from the public health, education, and transportation fields that may provide insights on how to develop future programs targeting older pedestrians.

To resolve the limitation of information safety and transmission speed in existing communication system,it applied the modular design method to design optical-electric combined THz wireless communication system framework,and determined 125GHz carrier frequency.Aiming at the core component optical emitter uni-traveling-carrier photodiode(UTC-PD) in THz wireless communication system,it analysed the relationship between output power,bandwidth and input signal types,and determined the emitter bandwidth by experiment.The result shows that the transmission speed in the system is able to reach 3.0Gbps when BER is less than 10-10.
