Sesame is an affordable, open-source mini quadruped robot powered by an ESP32 microcontroller. Designed by Dorian Borian, Sesame uses 8 MG90S metal-gear servos (two per leg) for 8-DOF locomotion and features a 128×64 OLED display that serves as an expressive robot face.

All mechanical parts are fully 3D-printable on a standard FDM printer. The hardware folder contains both parametric STEP and Fusion 360 source models alongside the STL files, allowing full customization. The frame, internal structure, covers, and leg segments are all available as individual STLs.
The ESP32 firmware handles inverse kinematics, face animations on the OLED display, and a WiFi-based control interface accessible from any browser. A desktop companion app (Sesame Studio) is included for easy gait configuration and pose tuning without writing code.
Community documentation covers full assembly with detailed wiring diagrams and a comprehensive BOM. Hat variants are available (enclosed, open, cat ears) for personality customization. With over 1600 GitHub stars, Sesame has become a go-to beginner quadruped platform.
