In an ironic twist that many people who lost their jobs due to competition from cheap labor overseas will appreciate, a Chinese firm discovered that machines are far cheaper than cheap labor. From South China Morning Post:
The machines can sort up to 200,000 packages a day and are self-charging, meaning they can operate around the clock.
An STO Express spokesman told the South China Morning Post on Monday that the robots had helped the company save half the costs it typically required to use human workers.
They also improved efficiency by around 30 per cent and maximised sorting accuracy, he said.
