Joseph L. Jones, a lifelong tinkerer and inventor, focuses on the practical application of robotic technology to real-world problems. In that pursuit he co-founded Tertill Corporation, a manufacturer of robots that weed home gardens, and Harvest Automation, Inc., a company that builds autonomous robots for the nursery and greenhouse industry. At both firms he served as CTO. Earlier, as senior roboticist, he spearheaded the development of Roomba, the world's first successful home floor-cleaning robot. A graduate of MIT, he is author of three earlier books on robotics and holds over 80 US and several international patents.
