You can do both CPU and GPU, but time and power consumption are both order-of-magnitude worse than using dedicated hardware. The robotic arms are also used untethered in factories, where having a computer near them is inconvenient. The article describes results for using a Xeon CPU. The linked paper cites other papers where a GPU was used.
