Comparative evaluation of 3D pose estimation of industrial objects in RGB pointclouds

3D pose estimation is a crucial element for enabling robots to work in industrial environment to perform tasks like bin-picking or depalletizing. Even though there exist various pose estimation algorithms, they usually deal with common daily objects applied in lab environments. However, coping with real-world industrial objects is a much harder challenge for most pose estimation techniques due to 3D pose estimation is a crucial element for enabling robots to work in industrial environment to perform tasks like bin-picking or depalletizing.

Continuous hand-eye calibration using 3D points

The recent development of calibration algorithms has been driven into two major directions: (1) an increasing accuracy of mathematical approaches and (2) an increasing flexibility in usage by reducing the dependency on calibration objects. These two trends, however, seem to be contradictory since the overall accuracy is directly related to the accuracy of the pose estimation of the calibration obj

Fast view-based pose estimation of industrial objects in point clouds using a particle filter with an ICP-based motion model

The registration of an observed point set to a known model to estimate its 3D pose is a common task for the autonomous manipulation of objects. Especially in industrial environments, robotic systems need to accurately estimate the pose of objects in order to successfully perform picking, placing or assembly tasks. However, the characteristics of industrial objects often cause difficulties for clas

Integrating mission, logistics, and task planning for skills-based robot control in industrial kitting applications

This paper presents an integrated cognitive robotics system for industrial kitting operations in a modern factory setting. The robot system combines low-level robot control and execution monitoring with automated mission and task planning, and a logistics planner which communicates with the factory's manufacturing execution system. The system has been implemented and tested on a series of automotiThis paper presents an integrated cognitive robotics systemfor industrial kitting operations in a modern factory setting.The robot system combines low-level robot control and execution monitoring with automated mission and task planning,and a logistics planner which communicates with the factory’smanufacturing execution system.

Using Robot Skills for Flexible Reprogramming of Pick Operations in Industrial Scenarios

Traditional robots used in manufacturing are very efficient for solving specific tasks that are repeated manytimes. The robots are, however, difficult to (re-)configure and (re-)program. This can often only be done byexpert robotic programmers, computer vision experts, etc., and it requires additionally lots of time. In thispaper we present and use a skill based framework for robotic programming. Traditional robots used in manufacturing are very efficient for solving specific tasks that are repeated many times.

Applying the Kanban method in problem-based project work: a case study in a manufacturing engineering bachelor’s programme at Aalborg University Copenhagen

Problem-based learning (PBL) has proven to be highly effective for educating students in an active and self-motivated manner in various disciplines. Student projects carried out following PBL principles are very dynamic and carry a high level of uncertainty, both conditions under which agile project management approaches are assumed to be highly supportive. The paper describes an empirical case stProblem-based learning (PBL) has proven to be highly effective for educating students in an active and self-motivated manner in various disciplines.

Streamlined Preparation of Immobilized Candida antarctica Lipase B

Candida antarctica lipase B (CalB) was efficiently expressed (6.2 g L-1) in Escherichia coli by utilizing an N-terminal tag cassette and the XylS/Pm expression system in a fed-batch bioreactor; subsequent direct binding to EziG from crude extracts resulted in an immobilized catalyst with superior activity to Novozym 435.

Lp(a) is not associated with diabetes but affects fibrinolysis and clot structure ex vivo

Lipoprotein (a) [Lp(a)] is a low density lipoprotein (LDL) with one apolipoprotein (a) molecule bound to the apolipoprotein B-100 of LDL. Lp(a) is an independent risk factor for cardiovascular disease (CVD). However, the relationship of Lp(a) to diabetes and metabolic syndrome, both known for increased CVD risk, is controversial. In a population based study on type two diabetes mellitus (T2DM) dev

Why Sweden Suspended Military Service : The Policy Process from 1990 to 2009

I lite drygt ett århundrade gestaltade den svenska värnplikten värderingar som jämlikhet, solidaritet och idén om att man skulle ”göra sin plikt och kräva sin rätt”. Värnplikten började som en rekryteringsmodell 1901, men förvandlades under 1900-talet till en institution i sin egen rätt: uppskattad av pliktskyldiga, Försvarsmakten, samhället, Högern och Vänstern. När det kalla kriget tog slut påböFor little more than a century military service enacted Swedish values of equality, solidarity and doing one's part for the public good. What started out at as mere military recruitment policy in 1901 developed into an institutional feature of Swedish society: appreciated by society, the conscripts, the Armed Forces and by political parties to the left and the right. In a pursuit to preserve milit

Development of high speed spectroscopic imaging techniques for the time resolved study of spark ignition phenomena

This paper reports on the development of novel time resolved spectroscopic imaging techniques for the study of spark ignition phenomena in combustion cells and an SI-engine. The techniques are based on planar laser induced fluorescence imaging (PLIF) of OH radicals, on fuel tracer PLIF, and on chemiluminescence. The techniques could be achieved at repetition rates reaching several hundreds of kiloThis paper reports on the development of novel time resolved spectroscopic imaging techniques for the study of spark ignition phenomena in combustion cells and an SI-engine.
