Maintaining Communication Link for Tactical Ground Robots

The communication link between a tactical mobile robot and its control station is currently the Achilles’ heel of any ground robotic operation in the field. High-bandwidth digital radios, while providing the robot greater mobility than tethered links, perform mostly on lines of sight. The communication link degrades quickly as a robot penetrates the interior of a building, tunnel, or cave, or i...

Autonomous Communication Relays for Tactical Robots

The high-bandwidth digital radio link between a mobile robot and its remote control station degrades quickly as the robot penetrates the interior of a building or becomes shielded by intervening terrain. This paper describes a current project that uses mobile autonomous communication relay nodes to overcome this problem. Each node is a small slave robot equipped with sonar, ladar, and 802.11b-b...

Physiological and Technical-tactical Analysis in Brazilian Jiu-jitsu Competition

PURPOSE The present study aims at investigating the physiological response and technical-tactical parameters in Brazilian jiu-jitsu competition. METHODS The study included 35 male Brazilian jiu-jitsu athletes (adult category, body mass: 80.2 ± 13.0 kg), graded from white to brown belt, during combats fought at regional level. Twenty-two fights were analyzed in terms of technique and time stru...
