Miniature mobile robots are very suitable for initiative reconnaissance and surveillance important targets of sensitive areas. However, miniaturization of robots will inevitably lead to lack of the power of locomotion. Throwable miniature robots can very kind to solve the above-mentioned problem. However, the crucial problem resulted from the small volume(More)
Throwable miniature robot can be deployed in important targets of sensitive areas by throwing, shooting, air-delivering or carrying by a small robot. So they are very suitable for secret reconnaissance and initiative detection in many military and civilian activities. However, the deployment mode of miniature mobile robots demands excellent anti-impact(More)
Before the soldiers or police take actions, a fast and real-time detection in dangerous places, such as indoor, passageway and underpass, can both guarantee the soldiers' safety and increase the battle's accuracy, so it is significative and necessary to design a kind of scout robot which is able to arrive in the target region to acquire the message fast by(More)
In this paper, a miniature reconnaissance robot with the functions of anti-impact and semi-autonomous motion is presented. The throwbot could be thrown or shot in the building by the soldier for real-time detection in anti-terrorist scene. A prototype has been developed to illustrate the concept. The finite element analysis and thrown experiments confirm(More)
Miniature detection robotic system with rapid deployment mode is very suitable for detecting in disasters due to its deployment mode. However, the deployment mode of the robot demands excellent anti-impact property. Moreover, another crucial problem resulted from the small volume of the robot is the difficulty of packing locomotion, sensing, computing and(More)

A simple, efficient and practical obstacle avoidance strategy for miniature mobile robot in the unknown environment is presented. In this paper, a series of virtual circles are approximated and gradually form the influence region based on the information of the unknown obstacle detected by the local sensing of robot. Then the limit cycle differential(More)
Detection in natural disasters or man-made disasters is more and more in important for every countries. Aerial dispersal miniature robots are very suitable for carrying the task above mentioned. However, the aerial dispersal deployment mode of miniature mobile robot demands excellent anti-impact property. Moreover, another crucial problem resulted from the(More)
The goal of this study was to investigate the effects of aging on pointing movements under restricted visual feedback of hand movement and target location. Fifteen young subjects and fifteen elderly subjects performed pointing movements under four restricted visual feedback conditions that included full visual feedback of hand movement and target location(More)
