This post seeks actuator recommendations for a quadruped robot's leg joints, emphasizing high torque-to-weight ratio and compactness in the R&D phase.

Polka v0.5.0 is now available, offering 6.2x faster deskewing and enhanced features for 2D/3D lidar processing, including live parameter tuning and diagnostics.

PlannerTrack is a simulation platform built on ROS2 for testing autonomous vehicle algorithms, supporting multi-agent coordination and heterogeneous vehicle models.

A small update on my robotic desk lamp: the entire control system now runs on a Raspberry Pi 5. The lamp uses 24 V RobStride BLDC servo motors connected over CAN. The Raspberry Pi now handles motor control, lighting, and animation playback locally, so the lamp no longer needs to be continuously controlled by my main PC. I still use a separate animation editor that I built for creating movements. Each joint has its own timeline with position keyframes, velocity, torque limits, and controller parameters. Finished animations are sent to the lamp and played back locally. I’ve also installed an

Hello hello, development of the upgrade, CubicDoggo 06R (High Mobility, sort of), is now complete, and the full project is documented on GitHub: https://github.com/SphericalCowww/CubicDoggo_06R The previous post can be found here. But yeah, the performance is not as ideal. You can see it's still wobbling when just standing there, and the IMU is not even balanced to be parallel to the ground. The effect of the IMU during walking is also difficult to notice because of how wonky it walks to begin with and how bad I am at controlling it to walk in a straight line, lol. However, you can see the

China solved the robot body. The brain is still up for grabs.  Jing Daily

If you ever wondered how a drone works, want to build a flight controller, or are just interested in robotics, embedded systems and STEM, this is for you. I've always been fascinated by flight, and my first attempt at building a flying object at 16 was a massive failure... But with perseverance, more education and lots of research, I have now built QuadFS, a drone (quadcopter) flight controller from scratch with STM32. QuadFS is an open drone flight controller built from the ground up in embedded C on an STM32 microcontroller. Every stage of the system is documented and explained so devel

Built from a 1980s RC helicopter mechanical rate gyro (futaba) and continuous rotation servo. The gyro normally has centering springs but they have been removed to increase sensitivity. The gyro has a hall effect sensor in it and an analog circuit which generates PWM pulses that the servo uses as a velocity control. A 3 axis version of this arrangement is what made the Apollo guidance computer so accurate at knowing its own pose over long distances and times. This single axis version could be a gyrocompass in a robot or aircraft, to maintain heading even if the magnetic compass quits workin

I will list the arguments commonly made in favor of humanoid robots and then rebut them each respectively: Many environments are indeed designed with the human body in mind, for instance door frame dimensions, door knobs, flat floors, staircases, etc. but it's a mistake to imply that only robots with human features can operate under these conditions, that only robots that have human hands and digits, only robots that have legs and feet, only robots that stand upright, only robots with a human head, etc. when this is obviously not the case. Wheels are compatible with flat floors, many kinds
