Maker Replicated the Boston Dynamics Gripper Using Daisy-Chained Servos and 3D-Printed Fingers Maker built a Boston Dynamics–style gripper using daisy‑chained bus servos and 3D‑printed fingers. Inspired by the Electric Atlas Humanoid Robots, the design focuses on a simple three‑finger layout with a rotating thumb to move around objects of different shapes. By linking multiple servos over a single UART bus, the build keeps wiring clean while allowing independent control of each joint for… |

Indian Team Trains Unitree G1 Humanoid for Classical Dance Using Motion Capture and Reinforcement Learning A humanoid robot named “Maya” has attracted attention in India after appearing on India's Got Latent, where it danced, rapped and interacted with people on stage. Maya is built on a Unitree G1 humanoid robot, but the Indian team behind the project added its own AI software, voice system, personality and custom movements. The team, associated with Tuesday Labs and students from Masters' Union,… |

Open-Source 7-DOF Tentacle Arm Uses ROS 2 MoveIt for Inverse Kinematics and Features a Holonomic Base James Bruton has built an open-source 7-DOF tentacle robotic arm that treats each joint as a 90° rotating stage, creating a highly flexible manipulator that can wrap around obstacles and reach into tight spaces. The design uses multiple Dynamixel servos chained into a serial kinematic chain, with custom 3D-printed links and structural parts to form a lightweight, compliant “tentacle” rather… |

Maker Builds a Fully 3D-Printed 6-DOF Bipedal Robot “Stompy” Using NVIDIA Jetson in Just 3 Days In an impressive display of rapid prototyping and engineering grit, creator Kayden Knapik successfully designed, built, and programmed a fully 3D-printed bipedal robot named Stompy in just 3 days. Utilizing the Bambu Lab P2S 3D printer, Knapik fabricated the robot's structure from scratch. The mechanical design features six degrees of freedom three per leg powered by six Robstride 02 motors,… |

Maker Built His Quadruped Robots a Soccer Field Where Ball Tracking Improved With Less Accurate Camera Data A maker built a miniature soccer environment for Sesame, a small quadruped robot, and demonstrated the system at the 2026 Open Sauce maker event. The build includes a scaled down soccer pitch sized for the robot, along with 3D printed goals and structural components. Multiple Sesame units are controlled wirelessly using the ESP-NOW protocol, with ESP32 chips on each robot communicating with a… |

This MicroDuck Robot Based on an RK3566 Has No Arms but Picks Things Up Using AI and Reinforcement Learning Hugging Face and Pollen Robotics just launched a tiny robot that could change how people learn robotics at home. Called Microduck, this 25cm tall, 780 gram biped robot is built specifically for reinforcement learning and physical AI and it costs just $399. Unlike Reachy Mini, which was designed primarily around interaction and conversational AI, Microduck focuses on physical movement and… |

Students Built a Submarine to Map Ice Thickness Across Frozen Lakes and Somehow Made GPS Work Underwater A team of engineering students from ETH Zürich has developed POLARIS, an autonomous underwater robot designed to measure and map the thickness of ice from underneath frozen alpine lakes. The idea is to make ice surveys safer and faster, especially in places where people need to know whether the ice is strong enough for activities such as racing or other work on frozen lakes. Traditionally, ice… |
