This dissertation presents a theoretical framework and algorithms for distributed wireless sensor networks and their physical implementations on tangible geometric games (TAG-Games) to assess cognitive and motor skills automatically using sensor integrated geometric blocks (SIG-Blocks) with an interactive graphical user interface. To allow for a variety of possible game designs, single and multiple blocks were used to form diff erent geometrical con figurations. To resolve communication issues between the blocks as well as reliability issues with sensing, the following distributed wireless sensor network algorithms were developed: 1) self-synchronization technique in a local network, 2) a hybrid wireless network, 3) an assembly detection algorithm, and 4) a motion sensing algorithm. The theoretical framework of this paper is that distributed wireless sensor network is fault tolerant, scalable, and a dynamic solution to complex multi-agent systems. To evaluate the validity of the TAG-Games with the developed algorithms and proposed theoretical framework, 86 participants were recruited to the human subject evaluation aging from 18 to 30. The results con firmed that the TAG-Games is suitable as an automatic assessment tool. The developed algorithms and theoretical framework are applied to three extended applications, including swarm robots, wearable sensors, and origami robots. First, two swarm robotic platforms were developed and the wireless algorithms were implemented. One of them is a group of mobile robots with corner reflectors to localize using directional received signal strength. The other one is the InchBots, a cubic inch-sized omnidirectional swarm robotic platform with a stackable hardware feature for customization. The robotic swarm aims to achieve a global goal by using a large number of robots, each with limited capabilities. In this application, the hybrid wireless network, assembly detection algorithm, and the self-synchronization algorithm were utilized and a geometry-based global shape formation algorithms were also implemented. The simulation results showed that the simple robotic agents can achieve global shape formation, i.e., line formation and radial dispersion, by using only received signal strength without centralized control. Second, wearable sensors were prototyped aiming to measure person-to-person interactions as well as biological and environmental data. Integration of the received signal strength from the proposed hybrid wireless network algorithm and motion detection algorithms were embedded in the system. Lastly, robots with a novel origami design were developed to achieve amphibious locomotion and articulated manipulation using the semi-soft origami structures. In this application, the data traffic resulting from real-time video streaming was controlled by distributing the hardware and internet protocol efficiently. The presented applications were then validated for the system efficiency, cost, reliability, and showed the great potential in the fi eld of robotics, clinical studies, and in education.
