The coupling of advanced sensors and<br />
actuators in industrial robots to create<br />
autonomous robots will have profound<br />
impacts on employment<br />
The Auto industry is already using big data<br />
and improved sensors to substitute for<br />
human workers<br />
Autonomous Robots<br />
Industrial robots are an exciting opportunity, however, it is in the coupling of the<br />
advanced sensors and actuators in industrial robots to machine learning algorithms<br />
to create autonomous robots that the most profound impact upon employment will<br />
be found. Many tasks have remained non-automatable by virtue of the difficulty of<br />
encoding the tacit knowledge we hold about how to interact with and manipulate our<br />
physical environment. For example, when navigating in a vehicle, we draw upon a<br />
rich knowledge of the automotive environment: we recall landmarks, interpret road<br />
signs and account for recent changes due to construction or snowfall in order to<br />
determine where we are in space. We might even use deep knowledge of culture<br />
and society in order to inform our judgment: for example, a dirt track is unlikely to<br />
lead to a supermarket, and a bus is most probably heading to or from a major<br />
settlement. However, in recent times, this complex tacit knowledge has not<br />
prevented the automation of driving: the Google self-driving car was licensed to<br />
drive in the US state of Nevada in 2012.<br />
The explanation for how human tacit knowledge was sidestepped is firstly found in the<br />
availability of increasingly instrumented vehicles. Mass-production vehicles, such as<br />
the Nissan LEAF, contain on-board computers and advanced telecommunication<br />
equipment that render the car as potentially a fly-by-wire robot. 65 Advances in sensor<br />
technology mean that vehicles are likely to soon be augmented with even more<br />
advanced suites of sensors. These will permit an algorithmic vehicle controller to<br />
monitor its environment to a degree that exceeds the capabilities of any human driver:<br />
they are not subject to distraction, have the ability to simultaneously look both<br />
forwards and backwards, and can natively integrate camera, GPS and LIDAR data.<br />
The big data provided by these improved sensors are offering a substitute to human<br />
tacit knowledge. Firstly, many modern vehicles offer Advanced Driver Assistance<br />
Systems (ADAS) that draw upon sensor data to provide adaptive cruise control,<br />
automated braking and even automated parallel parking. Further, the use of sensors<br />
to create three-dimensional maps of road networks has allowed for the automation<br />
of navigation; Google's driverless cars use an array of sensors to gather inchprecision<br />
readings of its environment costing over $150,000. 66 On-board algorithms<br />
can then compare a vehicle's current environment against prior maps stored on the<br />
vehicle in order to determine its location. Modern approaches store maps that<br />
characterise the different appearance of the environment throughout all the<br />
changing seasons (e.g. after snowfall). 67 Machine learning techniques have also<br />
been developed to identify unexpected changes to the road network, such as those<br />
due to road construction. 68 Many auto manufacturers are expecting to be able to<br />
offer autonomous vehicles between 2020 and 2025. 69<br />
Given their superior sensing capabilities, algorithms are thus potentially safer and<br />
more effective drivers than humans. This is no trivial contribution: road fatalities are<br />
within the top 10 global causes of death, with human error responsible for more<br />
than 90% of traffic accidents. 70 There are further potential contributions from<br />
autonomous vehicles: 20% of carbon dioxide (CO 2 ) emissions on the road are due<br />
to inappropriate accelerations, while 2% of US GDP is wasted because of<br />
congestion. If robotic vehicles join the Internet of Things, we can envisage a<br />
networked fleet of vehicles whose inter-communication and decentralised planning<br />
may be able to tackle these problems.<br />
