“Raphael is an extremely capable, intelligent, and humble engineer. The first time I met Raph, it was just after I had learned that his product was to be acquired to replace an internal development I had spent quite a bit of time and energy on. He was kind, excited, and interested in all of the ways that we could work together and learn from each other. His attitude and obvious positive intent made my role transition so much less difficult and painful. Due to company priorities, it took three years until I had the opportunity to work first for him, on the Root robot, and then with him on the Create platform. I am always amazed at his ability to keep an entire product in his head -- from concept and design, to customer need, through production with supplier relationships, and into sustaining and customer support. It is always impressive to me when I suggest a potential feature or delighter, and within a few hours he is showing me the perfectly formed prototype he's developed on his screen. In addition, his intuition about methods for resolving root cause for a problem -- hardware, software, or UX -- is second to none. Working with Raphael is a joyful, creative, and exciting experience, and he has been the keystone of our engineering team.”

Climbing favours the tripod gait over alternative faster insect gaits
Nature Communications
To escape danger or catch prey, running vertebrates rely on dynamic gaits with minimal ground contact. By contrast, most insects use a tripod gait that maintains at least three legs on the ground at any given time. One prevailing hypothesis for this difference in fast locomotor strategies is that tripod locomotion allows insects to rapidly navigate three-dimensional terrain. To test this, we computationally discovered fast locomotor gaits for a model based on Drosophila melanogaster. Indeed…
To escape danger or catch prey, running vertebrates rely on dynamic gaits with minimal ground contact. By contrast, most insects use a tripod gait that maintains at least three legs on the ground at any given time. One prevailing hypothesis for this difference in fast locomotor strategies is that tripod locomotion allows insects to rapidly navigate three-dimensional terrain. To test this, we computationally discovered fast locomotor gaits for a model based on Drosophila melanogaster. Indeed, the tripod gait emerges to the exclusion of many other possible gaits when optimizing fast upward climbing with leg adhesion. By contrast, novel two-legged bipod gaits are fastest on flat terrain without adhesion in the model and in a hexapod robot. Intriguingly, when adhesive leg structures in real Drosophila are covered, animals exhibit atypical bipod-like leg coordination. We propose that the requirement to climb vertical terrain may drive the prevalence of the tripod gait over faster alternative gaits with minimal ground contact.

How Root Wants to Bring Coding to Every Classroom
IEEE Spectrum
Root is a new kind of robot that colors outside the lines of the educational robotics category by providing unique capabilities along with a programming interface that grows with its user, bringing coding to life for all ages. After nearly three years of development, Root and its companion app, Root Square, have emerged as a solution to ease teachers’ anxiety about adding coding to the lessons that they teach.
