Season 5, Post 14: Robots to the rescue?
What does plastic pollution have in common with the lowest unemployment rate in a generation in the US? Robots can provide solutions to addressing some of the major issues that have arisen from these different dynamics. Remember, robots don’t get sick, ask for pay rises or hand in resignation notices – yet. They rarely break down too. We first made the case for industrial robots in July 2012 and service robots in April 2017.
Robots have been used to help assemble cars and semiconductor equipment for many years and the International Federation of Robotics estimates that there were 3.5m machines deployed worldwide at the end of 2021, the last year for which data were available. A recent article we read highlighted how improvements in hardware and software mean that robots are now being deployed to help sort waste. Niftier robotic arms and machine vision combined with AI-trained sorting methodologies mean that recyclable and non-recyclable substances can be better separated, keeping certain materials out of landfills. Only 14% of plastic is recycled annually (per the OECD), implying that every incremental innovation can help.
While readers of this piece are unlikely ever to visit a recycling facility, we are all familiar with eating out in restaurants. A number have begun tentatively to embrace robots. They can greet guests, lead them to their tables and deliver food. With 62% of US restaurant owners reporting that they don’t have enough employees to meet customer demand, introducing robots can help address the problem of labour shortages. Many believe they are more efficient too, minimising trips to and from the kitchen and reducing the risk of spillages or orders being brought to the wrong table. Have robots help and (the remaining) human servers can also spend more time with customers.
When asked about the biggest barriers to adoption, cost is the major issue. Waste-handling robots can cost as much as $300,000 each. For this price, you could purchase up to 20 restaurant robots. The price tag of the former is a function of their increased complexity. The good news is that the price of a typical industrial robot has fallen by more than 2.5 times in the last 20 years, as production has scaled, and component costs have fallen (all data from previously cited sources). Newer models should follow a similar price path. This potentially paves the way for more robots performing more complex tasks across an even broader range of industries in the future.
