Man-made machines took over the city as the year-long March of the Robots project went out with a bang.
Thousands of youngsters have taken part in 70 robot “mission labs” across the city over the past 12 months.
The ambitious scheme, commissioned by Leeds City Council, aimed to inspire creativity, ingenuity and participation among families, individuals and businesses.
Highlights of the weekend marking its grand finale included a huge civic robot cake; Sci-Fi Wi-fi enabled Roving Robot marching around Briggate; Lego robot building sessions and choc-bot constructing for chocolate lovers.
Hundreds of young computer-game fanatics attended the Minecraft Maker Party at Leeds City Museum while many dressed up in futuristic fashion and showcased their cyborg moves at a special “robo-bop” dance.
Emma Bearman, from organisers Playful Leeds, said: “It’s been a beautiful project to be involved in. People have shown a massive appetite for wanting to get off the sofa and play out and be really creative.”
