Episode 155 - Dr. Jae Son, Dr. Charles MacLeod, and Stu Shepherd
“Now tactile is an array of information that gives you insight into the contact mechanics between two objects.” Pressure is a scalar value. Force is a vector. Tactile sensing, says Pressure Profile Systems founder Dr. Jae Son, is something else entirely — a map of contact across an entire surface, the same sense humans rely on to pick up a coffee cup without crushing it, and one that most robots still don’t have. In this episode of “Manufacturing Matters,” TECH B2B Marketing’s Winn Hardin sits down with Dr. Son, PPS’s Dr. Charles MacLeod, and longtime robotics industry leader Stu Shepherd (Shepherd Solutions) to unpack why tactile sensing is finally getting its due — driven by humanoids and robots working in unstructured environments where fixed, pre-programmed grasps no longer cut it. The conversation covers PPS’s 65-point Tactile Glove (used both to collect human grasp data for robot training and, oddly, fitted directly onto robotic hands), and two very different medical spinouts: a radiation-free breast exam device now shown to outperform mammograms, and a new sensor for knee-replacement surgery that finally gives surgeons data instead of feel. Shepherd brings the industry-veteran perspective: Grip force has long been over-engineered because robots couldn’t tell how they were gripping something, and tactile data opens the door to lighter, smarter grippers. Dr. Son also pushes back on humanoid-robot hype, arguing the bigger near-term opportunity is smarter automation broadly, and walks through a very literal use case: giving assembly robots the ability to feel whether a connector clicked into place — something factory-floor noise often makes impossible to hear.
