Exact Motion Planning for Tractor-Trailer Robots
A tractor-trailer robot consists of a carlike tractor towing a passive trailer. Due to its highly nonholonomic nature, the kinematics of this type of robot are complicated and di cult to compute. We present exact closed-form solutions for the kinematic parameters of a tractortrailer robot and use them to construct an exact and e cient motion planner in the absence of obstacles. This local plann...
متن کاملExperiments in Autonomous Reversing of a Tractor-Trailer System
Trailer reversing is a problem frequently considered in the literature, usually with fairly complex non-linear control theory based approaches. In this paper, we overview our simple method for stabilizing a tractor-trailer system to a trajectory based on the notion of controlling the hitch-angle of the trailer rather than the steering angle of the tractor. The performance of this control method...
متن کاملTrailer Steering Control of a Tractor-Trailer Robot
In this paper, we consider active trailer steering control as a means to improve the maneuverability of (long) truck–trailer combinations during cornering. Hereto, we formulate the problem of reducing the so-called swept path width during cornering and that of eliminating unsafe tail swing of the trailer as a tracking control problem. We present a kinematic tractor–trailer model including off-a...
متن کاملRobust trajectory tracking for a reversing tractor trailer
Tractor-trailer reversing is a classical non-linear control problem in which many of the solutions proposed in the literature perform poorly in the presence of real-world constraints such as steering angle, rate limits and lags. In this paper we describe a new method in which an inner loop controls the hitch-angle of the trailer creating a virtual articulated vehicle to which existing control t...
متن کاملSite Layout Planning using Nonstructural Fuzzy Decision Support System
Site layout planning can affect productivity and is crucial to project success. However, as construction is heterogeneous in the nature of its organizations, project designs, time constraints, environmental effects, etc., site layout planning for each project becomes unique. Affected by many uncertainties ~variables! and variations, site layout planning is a typical multiobjective problem. To f...
