Tiny Robot “Sesame” Charms with Emotion and Affordability

A new quadruped robot named Sesame, created by inventor Dorian Todd, showcases that impressive technology does not need to be large or complex. This small robot, constructed from 3D-printed components, merges simple electronics with creativity, resulting in a delightful companion that displays a range of emotions.

The design of Sesame features four legs, each equipped with a pair of MG90S hobby servos. One servo rotates the leg around the vertical axis, while the other controls the foot’s movement. The entire system is managed by an ESP32 microcontroller, which allows for remote control through its built-in wireless connectivity. Additionally, Sesame is outfitted with a 128×64 OLED display that visually conveys its emotional responses.

Affordable and Accessible Robotics

While the mechanical design of Sesame might not be highly sophisticated, its ability to express emotions is remarkable. Dorian Todd demonstrates this emotional range in a project video, where Sesame playfully navigates a desktop, exuding the joy and liveliness often associated with a new puppy.

One of Sesame’s most appealing qualities is its affordability. Dorian estimates that anyone can build their own version of Sesame for approximately $60. For those interested in assembling this charming robot, the necessary files are available on GitHub.

In the world of robotics, Sesame stands out not only for its emotional display but also for its simplicity and accessibility. It invites enthusiasts and newcomers alike to explore the fascinating field of robotics without requiring substantial investment or technical expertise.

For those seeking quadrupeds designed with performance in mind, alternative builds are also available, showcasing the versatility of robotic design. As technology continues to evolve, projects like Sesame highlight the potential for creativity and innovation in creating engaging robots that capture the imagination.
