Cooperative micro-robotic scent tracking vehicles are designed to collectively “sniff out” locations of high scent concentrations in unknown, geometrically complex environments. These vehicles are programed with guidance and control algorithms that allow inter cooperation among vehicles. In this paper, a cooperative guidance and control algorithm for scent tracking micro-robotic vehicles is presented. This algorithm is comprised of a sensory compensation sub-algorithm using point source cancellation, a guidance sub-algorithm using gradient descent tracking, and a control sub-algorithm using proportional feedback. The concepts of social rank and point source cancellation are new concepts introduced within. Simulation results for cooperative vehicles swarms are given. Limitations are discussed.

To solve the multi-interceptor coordination problem and to intercept the target with impact angle constraint, a novel distributed cooperative control algorithm with impact angle constraint based on integrated guidance and control is proposed. First, the mathematic model of integrated guidance and control is established by combining the interceptor-target relative motion model with the dynamic equation of the interceptor on pitch plane. The time varying gain extended state observer is developed to estimate and compensate the unknown disturbance. Based on the estimated value and fast nonsingular dynamic surface sliding control method, the IGC algorithm of leader is given; Then, based on distributed cooperative "leader-follower" model, the cooperative control strategy of multi-interceptor is designed, and gives out speeds in two directions on pitch plane, which are transformed to the command of total velocity and trajectory angle based on kinematic relations. Finally, to control the follower, the time varying gain extended state observer and the dynamic surface sliding control method are adopted. The simulation results demonstrate the effectiveness of the distributed cooperative control algorithm.

In this paper, a robotic vehicle for a personal mobility with electric-driven three-wheels is proposed. Before designing the proposed robotics vehicle, omni-directional motions using special wheels, active caster wheels, and active steerable driving wheels are studied. For design of the proposed vehicle, we discuss about active steerable wheel design, and vehicle’s frame design. The omni-directional motion through the digital design exploration of the vehicle using active driving and steering wheel robot technology is examined. As the major mechanical components, an active steerable driving wheel, in-wheel motors, brakes, suspensions, and control systems are described. The design is established by rapid prototyping model of omni-directional motion. The steering geometry and control algorithm for the prototype of the proposed personal mobility are experimented.
