The myBuddy 280 Pi is a dual-arm 13-DOF (Degrees of Freedom) humanoid collaborative robot powered by a Raspberry Pi 4B mainboard and M5Stack ESP32 co-processors. Designed as an all-in-one desktop service robot, it features two 6-axis collaborative arms and a 1-axis torso/waist rotation mechanism.
Equipped with a built-in 7-inch interactive display screen and dual 2-megapixel HD cameras, myBuddy 280 provides a rich, cost-effective platform for dual-arm motion planning, computer vision research, embodied AI, and interactive human-robot interaction (HRI).
Key Applications and Functions
- Dual-Arm Coordination: Enables dual-arm manipulation research such as two-handed picking, object passing, bi-manual assembly, and coordinated sorting tasks.
- Computer Vision and AI: Dual 2MP cameras allow for stereo vision, 3D object location, face recognition, gesture tracking, and visual path planning.
- Interactive Humanoid Display: The integrated 7-inch touchscreen supports built-in facial expressions, custom UI displays, and direct touch interaction.
- Desktop Research and Education: Serves as a compact platform for robotics education, AI lab setups, and commercial exhibitions.
