propellers, water-jet, valves and pumps are realized in different underwater robots -. In some special tasks, such as path planning, obstacle avoidance, etc., underwater robots are also required to have multiple degrees of freedom, good stability and flexible swimming work . Th e …
The employment of trajectory tracking strategies with obstacle avoidance capabilities is essential to avoid time waste and inefficiency in mobile robots industrial integration. In this paper, we present a navigation algorithm intended for differential drive mobile robots, that combines trajectory tracking with obstacle avoidance.
lished. In Section 3, the mixing qualitative and quantitative criteria are established, and the concrete realization method of the model described by the super-quadric function and the model described by the geometric function are analyzed. In Section 4, obstacle-avoiding trajectory planning using a modiﬁed modal function is analyzed.
Feb 14, 2018 · ORB-SLAM2. These techniques try to build a map with the features they use to locate themselves. Depending on the approach, these features may be considered obstacles and may be used for obstacle avoidance or even complex trajectory planning. Search on youtube to see some of these techniques in action and see which one suits you better ;) Here
Dynamic obstacle avoidance is essential for unmanned surface vehicles (USVs) to achieve autonomous sailing. This paper presents a dynamic navigation ship domain (DNSD)-based dynamic obstacle avoidance approach for USVs in compliance with COLREGs. Based on the detected obstacle information, the approach can not only infer the collision risk, but also plan the local avoidance path trajectory to

Dec 10, 2013 · Trajectory Planning of Boom System Based on Improved PSO. Because of the redundancy and difference of working requirement and environment, the improved PSO algorithm is adopted to solve the inverse kinematic problem of the boom system when the concrete pump truck work. The calculation procedure is shown in Figure 3.
planning for environments involving both static and moving obstacles ; and of robust path planning , . A serious problem associated with MPC-based motion planning is the unavoidable presence of non-convex state constraints arising from the obstacle-avoidance requirement. The MILP formulation discussed in  is one approach to
An obstacle avoidance technique is a mechanism that, given an obstacle configurationand a initialand goalpositions, computes the best motion to drive the vehicle to the The result is a trajectorythat joins the initialand the goal. are: (i)obstacle distributionand (ii)initialand goalconfigurations.

Within each warehouse, the polynomial based paths are subject to constraints such as motion boundaries, kinematics constraints, obstacle-avoidance, limited resource of elevators and smoothness. We formulate the shortest path planning problems as one time-varying nonlinear programming problem (TNLPP) while restricted to the above constraints
In this thesis we introduce trajectory bundles, and develop algorithms that use them to enable perception-driven planning. We develop a trajectory clustering algorithm that enables us to construct a set of trajectory bundles. We then develop a Bayesian ﬁltering framework that enables us to estimate a belief over which trajectory bundles are
