Antoine Weill--Duflos
I build interfaces you can touch, robots you can feel, and ideas you can hold.
Head of Technology and Applications / Haply Robotics
I lead technology and applications at Haply Robotics in Montreal, where we build haptic robots that let people physically feel and interact with the digital world. Our products are used by 150+ customers including Fortune 500s, we have won CES Innovation Awards multiple years running, and we work with some of the biggest names in tech and robotics to push physical AI forward.
I hold a PhD from Sorbonne Université (Paris) and an engineering degree from Arts et Métiers ParisTech. My research took me from micro and nano teleoperation to haptic device design, perception studies, and human-robot interaction, which eventually brought me to Canada for a postdoc at McGill’s Shared Reality Lab. Along the way, I co-authored a few patents, published a bunch of papers, and I teach haptics, engineering, and human-machine interaction at a few Canadian universities.
Outside of work, I run a self-hosted homelab that I blog about, tinker with home automation and open-source projects, and occasionally build things that have nothing to do with haptics.
Devices, experiments and open-source builds.
A handheld ESP32-C6 device that synthesizes the feeling of a ball rolling and sliding inside a tube you cannot see, reproducing Yao and Hayward’s 2006 virtual rolling stone. Two haptic output paths: an I2S amplifier driving a TITAN Haptics actuator, and an H-bridge driving a motor directly. Ongoing personal project.
cortexmd is an open-source long-term memory and code-navigation brain for AI agents, exposed over the Model Context Protocol. It gives an agent a persistent memory that survives across sessions and a way to navigate a codebase by querying an index instead of reading whole files into context. Self-hosted, MIT licensed, pre-alpha.
