Did you know?
Jaco is named after one of the founders' uncles, who was an inventor and built an early robotic arm himself.

History
Kinova was founded in 2006 by Charles Deguire and Louis-Joseph Caron L'Ecuyer, two young Canadian engineers with a desire to become entrepreneurs. Deguire grew up with three uncles who had muscular dystrophy and lived confined in power wheelchairs controlled only with the small residual movements left in their fingers. One of the uncles, Jacques Forest, was an inventor and had already devised an ingenious mechanical arm that could pick up all kinds of objects. Motivated and inspired by his inventive uncle, who passed away in 1993, Deguire teamed up with L'Ecuyer to design a new robotic arm. Thus was born Jaco. Kinova has since created a broad range of robot arms for industrial, professional, and medical applications.
