A UK research team has created one
of the first robots capable of handling unfamiliar objects, and it may soon
become dexterous enough to load a dishwasher, The Financial Times reported.
"Boris 2" was first
showcased at the British Science Festival in Birmingham last
Thursday. Boris's blue arms and silver hands
allow him to grasp objects like a human can.
The machine cost £350,000 ($570,000)
and took five years to develop. Once its development is complete, it will
represent the answer to one of the most complicated problems in robotics: How
can a machine assess the size and weight of an object it has never encountered
before, and calculate correctly the best way to pick it up? The problem has a
massive number of variables and requires a staggering amount of calculations
(and yet humans do it subconsciously).
Boris is one of the first robots capable of grabbing objects in a human-like
fashion. For a while now, robots have been able to pick objects up if they have
been specifically programmed to do so - but they haven't been able to
manipulate unfamiliar, random objects they have not seen before.
Before now, robots could only pick up items of a fixed size in a stationary
location.But Boris is able to calculate a 1,000 possible ways to grab an object in the space of 10 seconds
The team of computer scientists from
the University of Birmingham who made the robot believe that it will be capable
of carrying out complex tasks such as loading a dishwasher, hopefully by April
next year.
Professor Jeremy Wyatt, of the
University of Birmingham's computer science department, told Business Insider:
"It's a really interesting technology you can apply in many circumstances.
Our next step is working with tech organizations to see how we can use robots
to assemble industrial parts."
Boris is shown grasping a small bowl
at the British Science Festival in Birmingham.
However, the intention with robots
like Boris is not to replace humans in the workplace, but to help and work
collaboratively with them. "We want to augment existing human abilities,
but still get the human to do the parts of the job the robot can't do,"
says Wyatt.
Researchers taught Boris different ways of grasping objects, for example
through a power grip using its whole hand to curve around an object or a pinch
grip between two or three fingers. This level of dexterity is required for a
robot to manipulate a variety of objects of different sizes in an environment
like an office or household.
The robot can "see"
objects in front of it using depth sensors embedded in its face and wrists.
However, Boris still finds some objects hard to pick up - for example, shiny
objects, which its sensors often find difficult to detect due to reflections
off the material confusing the robot as to where the object actually is.
Wyatt has big plans for the future. "Over
the next four to five years, we will see a whole series of algorithms for
different robot manipulations. In the seventies and eighties, we saw robotic
manipulation under structured and controlled environments, like in factories.
Now, we can produce robots that navigate around unstructured environments and identify
and grasp unfamiliar objects. That is what is coming to the market now."
