In 2017, a technology firm in India introduced a robotic arm to perform “aarti,” a ritual in which a devotee offers an oil lamp to the deity to symbolize the removal of darkness. This particular robot was unveiled at the Ganpati festival, a yearly gathering of millions of people in which an icon of Ganesha, the elephant-headed god, is taken out in a procession and immersed in the Mula-Mutha river in Pune in central India.
Ever since, that robotic aarti arm has inspired several prototypes, a few of which continue to regularly perform the ritual across India today, along with a variety of other religious robots throughout East Asia and South Asia. Robotic rituals even now include an animatronic temple elephant in Kerala on India’s southern coast.
