ACHIRES: Bipedal Running Using High-speed Visual Feedback – (video).
ACHIRES is an “Actively Coordinated High-speed Image-processing Running Experiment System.” It is composed of high-speed vision and high-speed actuators to achieve instantaneous recognition and behavior. The similar technologies are used in our Janken (Rock Paper Scissors) Robot. High-speed vision recognizes the state of the biped robot at 600 fps for stable running without falling. The biped mechanism with the leg length of 14 cm is set to run in the sagittal plane. The running velocity of 4.2 km/h is achieved with simple control based on high-speed performance of sensory-motor system, unlike with computationally expensive ZMP-based control commonly used for balance. The aerial posture is recovered to compensate for the deviation from the stable trajectory using high-speed visual feedback. We also address a task of somersaulting. ACHIRES is going to be improved to push the envelope while demonstrating various biped locomotion tasks.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
