Industrial robots are complex machines that perform a variety of operations in any business, regardless of the industry it belongs to. These robots operate 24/7 to perform the required tasks and are subjected to wear and tear like any other technological equipment.

In 2018, the sales of industrial robots soared up to a whopping US $16.5 billion around the globe, which was a 1% increase than the global sales recorded in 2017. Approximately 2.4 million robots were working in different industries, as of 2018. This figure is further estimated to reach up to 4 million industrial robots working

The robotics industry has continually evolved over the years. While previously, people were skeptical about the use of industrial robots, as they felt threatened that robots would eventually replace them – that’s no longer the case.

The earliest use of unmanned balloons was in 1849, when Austrians attacked Venice by attaching explosives to them. The world then saw the United States developing Unmanned Aerial Vehicles (UAVs) in World War I, circa 1916. The country successfully created the first pilotless aircraft, which then led to experiments with radio-controlled aircraft by 1937.
