These Handheld robots can guide you in everyday tasks

A team of researchers have developed a prototype of handheld robots which can understand how best to interact with a tool that "knows and acts".

The researchers of University of Bristol 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.

Dr Mayol-Cuevas, Reader in Robotics Computer Vision and Mobile Systems, said that there are three basic levels of autonomy they are considering i.e. 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.

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.
