LABO-4 robot, the latest model in the popular LABO series, is an intelligent robot platform with high payload which can be configured for a wide range of experiments and real-world applications. As in other LABO models, it has a flat payload surface for serious mobile experiments and on-board applications. With its two powerful motors and low center of gravity, LABO-4 operates very smoothly indoors and outdoors over varied terrains. Other features include 25.5 cm (diameter) high traction pneumatic tires and pivoted casters. The speed can be adjusted continuously from snail's speed up to 6.5 km/h (180 cm/sec). The robot is equipped with ultrasonic and infrared sensors for obstacle avoidance and can be programmed to maneuver autonomously or semi-autonomously in complex real world environments. With the basic software built using behavior-based AI theory, 8 hours of continuous autonomous operation with 30 kg payload is possible. Optional vision system allows experiments on free space detection and landmark-based navigation. There is a choice of several on-board processors: the default PC/104 processor, MC68332 single chip computer, a notebook PC, the Korebot board, and PIC(s), to meet the needs of experiments.
