The annual Robots on Ice event took place in San Jose, California, with robots small and large skating across a rink. The event aims to inspire attendees to pursue STEM and is hosted by the Silicon Valley Ice Skating Association (SVISA), a nonprofit organization aimed at cultivating ice skating throughout Silicon Valley. The robots, which can be controlled by humans, ranged from miniature dog and cat robots to a full-sized replica of Dalek from TV show "Doctor Who". Many robots and their handlers return to the event year after year. The Marauder, a 250 pound, six-foot long robot with six legs, was controlled by its handler, Nick Donaldson, who designed, programmed and built the bot.
