This paper presents a human dead-reckoning system for beaconless indoor positioning. The system is based on traditional dead-reckoning sensors like compass, gyro, and accelerometers. Due to the difficult kinematics of a human, there are no ready solutions for the odometry. This problem is solved by using a self-made stride length measurement unit and laser(More)
Mars is currently the centre of interest for space exploration. Tremendous efforts are still in progress to find clues of existence of life on Mars. Rovers are major sources of information of Mars. This paper focuses on a robotic roving vehicle robot for scientific applications (ROSA) having its initiative of European Space Agency (ESA). ROSA being a(More)
This paper describes the assessment of the most relevant astronaut assistant activities on the surfaces of the Moon and Mars and, furthermore, the robotic technology development requirements to implement these activities with a centaur-like outdoor service robot, called the WorkPartner. The activity assessment is done by extracting five common mission(More)
Space of two categories connects wievers emotionally with their own childhood. Each person entering the installation space creates a human-shaped view to the world of a little girl with their own shadows. The shadows act as gateways to another temporal state, which is illuminated inside shadows, normally dark and void. The installation deals with the(More)
This paper presents a human localization system for beaconless indoor positioning. The system is based on traditional dead-reckoning sensors including a compass, a gyro, and accelerometers. Due to the difficult kinematics of a human, there are no ready solutions for the dead reckoning. This problem is solved by using a self-made stride length measurement(More)
— One problem in current human-robot task communication is the laborious need to define action and target object parameters for each task request. This paper's solution to the problem is to enable indirect task communication by mimicking the human cognitive ability to understand affor-dances, i.e. action possibilities in the environment with respect to(More)
