wu no. 25 pulling his creator and owner, wu yulu, along in a rickshaw

without a university degree or academic learning, chinese farmer, wu yulu has managed to build himself
an army or 26 robots over the last 30 years made from scrap materials. each one takes its name from wu,
and are numbered according to the sequence in which they were made. the robots all vary in ability,
indicating that wu's robot building skills have improved over the years. his first robot, wu no. 1 took a few years
to build and barely moved, taking very short steps. whereas his recent wu no. 25, actually has the capability
of pulling its owner around in a rickshaw for up to 6 hours on a single charge.
