چکیده

We propose a methodology to automatically generate plans for a robot excavator like a bucket loader or a backhoe. The task is formulated as one of constrained optimization in an action space that is spanned by the parameters of a prototypical digging plan. We show how geometric and force constraints are imposed on the action space to build the set of feasible plans, and discuss methods to optimize a cost function within this set. We discuss recent simulation results that demonstrate this method in action.

Synthesis of Tactical Plans for Robotic Excavation

This thesis describes an approach to synthesizing plans for robotic excavators. Excavation tasks range from loading a pile of soil to cutting a geometrically described volume of earth— for a trench or foundation footing. The excavation task can be stated in terms familiar to researchers in robotics and artificial intelligence: Transform the world from its current state to another state. Two imp...

Robotic Excavation in Contruction Automation - IEEE Robotics & Automation Magazine

C onstruction is of prime economic significance to many industry sectors. Intense competition, shortages of skilled labor, and technological advances are forcing rapid change in the construction industry, thus motivating construction automation [1]. Earthmoving machines, such as bulldozers, wheel loaders, excavators, scrapers, and graders, are common in construction. Excavationbased operations ...

A Control Architecture for Robotic Excavation in Construction

This article presents a hybrid control architecture developed for robotic excavation. The lower-level controllers are designed using a combination of sliding mode control and fuzzy logic control. Control strategies at the higher level involve task decomposition in association with statecharts, and task execution and verification. Typical machine tasks are decomposed into subtasks and/or states....

An Operation Space Approach to Robotic Excavation

We propose a methodology to automatically generate robot actions for tasks that cannot be abstracted into a geometrical basis because ofed into a geometrical basis because of complex interaction between the robot and the world. Our method considers such a task, robotic excavation, by seeking to satisfy constraints posed by the robot and the world to generate “plans” that optimize an arbitrary c...

Designing a Robust Control Scheme for Robotic Systems with an Adaptive Observer

This paper introduces a robust task-space control scheme for a robotic system with an adaptive observer. The proposed approach does not require the availability of the system states and an adaptive observer is developed to estimate the state variables. These estimated states are then used in the control scheme. First, the dynamic model of a robot is derived. Next, an observer-based robust contr...
