(Takahiro Takizawa) YUASA, Wakayama Prefecture--As the aspiring robot designer slogged away loading mikan fruit into wheelbarrows, it occurred to him that surely there had to be a less exhausting way to do it. “Transferring mikan was tough, and I remember thinking if I could do something to make the process easier,” says Mizuhito Terashima, founder of CuboRex, a Tokyo-based startup that has developed a system to electrify wheelbarrows for agricultural and engineering work. He hails from Yuasa, Wakayama Prefecture. Mikan farmers in Wakayama and Ehime prefectures and other clients across Japan are embracing the E-Cat Kit, which can be used to modify various types of carts, to move loads more easily.
