Electromechanica Inc. was tasked with researching and developing a proof of concept robot tool for in-situ pipe inspection of fleet piping. Electromechanica has designed and fabricated a proof of concept robot tool based on a pneumatically actuated peristaltic motion. This motion is accomplished by the use of inflatable pneumatic grippers, as well as a novel flexible pneumatic cylinder capable of actuation in a variety of articulated positions. Various representative piping systems were used to successfully test locomotion and guidance of the system.

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.

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.
