Om jobbet


For autonomous machines operating in a dynamic environment, it is important to
maintain up-to-date representations of the environment. GNSS solutions provide
near-accurate localisation for machines in large open areas, but perception-based
localisation and mapping is more performant for many safety-critical autonomous
heavy-machine operations, including obstacle detection and avoidance. A key
component is determining the type of perception sensors (cameras, LiDARs,
RADARs) and the sensory configuration in order to accurately estimate the state of
the objects in the environment. The local map from perception-based sensors could


be combined with GNSS estimates to determine the state of a heavy-machine in the
global map during operations. Thus the aim of this project is to investigate
perception solutions that can be utilised to increase efficiency and safety in terms of
obstacle detection and avoidance. The state localisation and mapping project works
in close collaboration with a control systems researcher to develop autonomous
solutions for loader cranes.


We are looking for a skilled state localisation and mapping engineer. We offer a
challenging position in our diversified team of highly qualified engineers.


The job responsibilities


The job responsibilities of the candidate include developing and testing state
estimation algorithms for localisation and mapping of loader cranes in dynamic
environments, working with and testing perception sensors in our closed- and open-
lab environments. The candidate will work in collaboration with a control system
researcher to develop autonomous loader crane operations. In addition, the
candidate is expected to perform research as an Early-Stage Researcher (ESR) in
perception-based localisation and mapping in accordance with the scientific
objectives below.


The scientific objectives include:


1) To provide an expressive yet compact representation of the environment along
with localisation and tracking capabilities. The representation needs to be flexible
and versatile to also accommodate surface parameters to allow for energy-efficient
motion planning and reasoning


2) To allow for a smooth transition between GNSS and perception-based localisation


3) To improve the extraction of dynamic objects and obstacles by utilising previous
knowledge from revisited regions.


The ESR will acquire a broad range of knowledge of the state of the art in related
fields, such as dynamic mapping, state estimation and localisation. The ESR will
also be involved in dissemination through social media promotion of the
MORE-ITN network (an EU Horizon 2020 funded programme), such as surveys,
LinkedIn groups, YouTube video channels, Twitter and blogging.

We offer
Our control system consists of hydraulics, electronics and software algorithms, and it is essential to tune these together with the mechanical system to create good dynamic behavior for the complex loader crane system. We are looking for a skilled Control Systems Engineer with a background in machine learning. We offer a challenging position in our diversified team of highly qualified engineers.
The job responsibilities
We consider a task where a large-scale robotic arm with an under-actuated end-effector moves an unknown load to a goal position while avoiding collisions with the environment. We assume access to a high fidelity simulator. Reinforcement learning is a potential solution to this task due to not requiring a perfect dynamics model or a complicated reward/cost model. However, for complex tasks reinforcement learning requires a large amount of training data generated during the training process. In principle, a simulator can be used to generate the data and the solution then transferred to the real robot.
The scientific objectives include:
1) While there is recent work on both reinforcement learning with sim-to-real and obstacle avoidance and also demonstrations of these on real robots, we are not aware of work that combines sim-to-real and obstacle avoidance on under-actuated large-scale machines;
2) To learn behaviour on the simulator of crane A, transfer to and fine tune the behaviour on real crane A, and then transfer the solution to real crane B, for which a simulator does not exist.
The ESR will acquire a broad range of knowledge of the state of the art in related fields, such as simulation, reinforcement learning, imitation learning.
The ESR will also be involved in dissemination through social media promotion of the network, such as Webropol surveys, and LinkedIn groups, YouTube video channels, Twitter and blogging.
