In this study which has been conducted in Akçasu Forest Range District of Devrek Forest Directorate; 3 methods (weed control with labourer power, cover removal with Hitachi F20 Excavator, and weed control with agricultural equipment mounted on a Ferguson 240S agriculture tractor) were utilized in weed control efforts in regeneration of degraded oriental beech forests have been compared. In this...

The results of the study developed mathematical model and laboratory installation lifting engine a mining excavator, which allow, with least intervention in control system to receive current signal proportional weight rock mass moving bucket are presented

Alat berat merupakan faktor pendukung yang sangat penting dalam suatu proyek terutama pada skala pekerjaan besar. Penggunaan alat bertujuan untuk memudahkan sumber daya manusia pelaksanaan tersebut. Khususnya di wilayah kabupaten Gunungkidul saat ini sedang banyak melakukan pembangunan Jalur Jalan Lintas Selatan (JJLS). memiliki letak geografis pegunungan kapur atau karst maka tidak memungkinka...

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 optim...

In this paper, an infrastructure for monitoring remote equipment and solving some of the logistic challenges of operating satellite surface mines is presented. This infrastructure includes strategies for communicating timely and accurate information amongst operators, planners and supervisors, using off-the-shelf network protocols. Advanced data visualization techniques are implemented, so user...

This paper presents a novel approach for applying behaviour-based concepts at a high, deliberative layer of a robot control system. Complex tasks which a robot shall fulfil are typically specified using finite-state machines. It is shown here that behaviour-based systems can be used to implement such machines. This allows for realising complex tasks and at the same time benefit from the advanta...

with the world as excavation. In order to effectively plan its actions, our robot excavator requires a method that allows it to predict the resistive forces experienced as it scoops soil from the terrain. In this paper we present methods for a robot to predict the resistive forces and to improve its predictions based on experience. We start with a simple analytical model of a flat blade moving ...

The paper at hand presents a novel, biologically inspired approach to numerically solve the inverse kinematics problem of arbitrary kinematic chains without instability problems and with low computational complexity. The kinematic chain of the robot arm is transferred to a network of behavior-based joint controllers, which try to deliver the best control value to solve the global problem. By me...

In the article, using computer simulation in Ansys environment, working process of replacement equipment a single-bucket excavator for soil compaction under pipeline is investigated and influence parameters on qualitative picture change stress-strain state main evaluated.

Bucket is key and primary component of heavy construction machinery such as excavators. It has to bear high impact loads during digging process, resulting in large stress deformations. This research work been focused on reducing deformations produced excavator bucket due digging. For this purpose, different design patents buckets (including ornamental designs) were considered. Various models de...
