Small radio controlled (R/C) rotary-wing UAVs have many potential military and civilian applications, but can be very difficult to fly. Small and lightweight sensors and computers can be used to implement a control system to make these vehicles easier to fly. To develop a control system for a small UAV, an 8-bit microcontroller has been interfaced with MEMS(More)
The need for intelligent unmanned vehicles has been steadily increasing. These vehicles could be air-, ground-, space-, or sea-based. This paper will review some of the most common software systems and methods that could be used for controlling such vehicles. Early attempts at mobile robots were confined to simple laboratory environments. For vehicles to(More)
This paper describes the development of a system that uses computational psychology (the Soar cognitive architecture) for the control of unmanned vehicles. A multithreaded software system written using Java and integrated with the Soar cognitive architecture has been implemented on two types of mobile robots. Soar can be used as a general purpose robotic(More)
Unmanned vehicles (air-, ground-, and sea-based), or mobile robots, have become increasingly important for both civilian and military applications and both intelligence and autonomy are important for these vehicles and their continued success. Many of these vehicles, however, currently require significant human supervision. For example, the Predator and(More)
This paper describes the development of the Cognitive Robotic System (CRS) for studying intelligent and autonomous unmanned vehicles. This system uses a multi-threaded software system written using Java to integrate the Soar cognitive architecture with a sixlegged mobile robot and its sensors and motors. The results of experiments in which the Cognitive(More)
Small, semi-autonomous rotary-wing UAVs have many potential military and civilian applications. A quadrotor, one such UAV with four fixed pitch rotors, has become popular in recent years. This UAV can be highly maneuverable, has the potential to hover and to take off, fly, and land in small areas, and can have simple control mechanisms. However, a quadrotor(More)
This paper presents steering behaviours through intelligent agents populating virtual or simulated environments. We present a reliable effort towards automatic path planning of intelligent computer agents with the integration of trajectory optimisation and obstacle avoidance techniques. Our approach will increase the level of accuracy in movement and would(More)
