What if handheld tools know what needs to be done and were even able to guide and help inexperienced users to complete jobs that require skill? Researchers at the University of Bristol have developed and started studying a novel concept in robotics - intelligent handheld robots.
Historically, handheld tools have been blunt, unintelligent instruments that are unaware of the context they operate in, are fully directed by the user, and critically, lack any understanding about the task they are performing.
Dr Walterio Mayol-Cuevas and PhD student, Austin Gregg-Smith, from the University's Department of Computer Science, have been working in the design of robot prototypes as well as in understanding how best to interact with a tool that "knows and acts". In particular, they have been involved with comparing tools with increasing levels of autonomy.
Compared to other tools such as power tools that have a motor and perhaps some basic sensors, the handheld robots developed at Bristol are designed to have more degrees of motion to allow greater independence from the motions of the user, and importantly, are aware of the steps being carried out. This allows for a new level of co-operation between user and tool, such as the user providing tactical motions or directions and the tool performing the detailed task.
Handheld robots, aim to share physical proximity with users but are neither fully independent as is a humanoid robot nor are part of the user's body, as are exoskeletons. The aim with handheld robots is to capitalise on exploiting the intuitiveness of using traditional handheld tools while adding embedded intelligence and action to allow for new capabilities.
Dr Mayol-Cuevas, Reader in Robotics Computer Vision and Mobile Systems, said: "There are three basic levels of autonomy we are considering: no autonomy, semi-autonomous when the robot advises the user but does not act, and fully autonomous when the robot advises and acts even by correcting or refusing to perform incorrect user actions."
The Bristol team has been studying user's task performance and user preferences on two generic tasks: pick and drop of different objects to form tile patterns, and aiming in 3D for simulated painting.
Austin Gregg-Smith, a PhD student who is sponsored by the James Dyson Foundation, added: "Our results indicate that users tend to prefer a tool that is fully autonomous and there is evidence of a significant impact on completion time and reduced perceived workload for autonomous handheld. However, users sometimes also expressed how different it is to work with this type of novel robot."
The researchers are currently investigating further topics on interaction, shared intelligence and new applications for field tasks, and due to the difficulties of starting in a new area of robotics, their robot designs are open source and available via http://www.
A paper about their recent work, which has been nominated for Best Cognitive Robotics Paper Award, Best Student Paper Award and Best Conference Paper Award, will be presented at this week's IEEE International Conference on Robotics and Automation (ICRA).

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
