This project provides a complete set of design files and hardware specifications for a 3D-printable industrial-style robot arm. The system includes a CAN bus robot controller for managing stepper motors and sensors, a kinematics engine for calculating joint angles and poses, and a UDP-based Python API for sending motion commands and monitoring telemetry. The system features a force-controlled robotic gripper that utilizes field-oriented control on stepper motors to enable compliant grasping and precise force sensing. It also includes a 3D position visualization tool for real-time telemetry tr

WiFiManager is a captive portal and web server framework used for configuring wireless credentials and network settings on ESP8266 microcontrollers. It provides an embedded network configuration interface that allows users to connect devices to a wireless network via a web browser rather than hardcoding credentials. The system functions by temporarily acting as a wireless host and redirecting incoming web requests to a local configuration page. It distinguishes itself through a customizable portal that supports user-defined input parameters, visual themes, and multi-language localization to c

RLinf is a distributed reinforcement learning orchestrator and embodied AI training framework. It provides the infrastructure to train vision-language-action models and robotic policies using a combination of reinforcement learning and supervised fine-tuning. The system is designed for scaling workloads across GPU clusters, managing the placement of actors, rollout workers, and environment components. It features a specialized robotics data collection pipeline for gathering teleoperated demonstrations and simulation trajectories into standardized replay buffers, alongside a hardware interface

OctoPrint is a web-based platform for remotely controlling and monitoring 3D printers. It provides a browser dashboard to start, pause, cancel, and track print jobs, while streaming real-time printer status, temperature, and progress updates. The system is built around a plugin-based architecture that allows extending core functionality, and it offers a documented REST API for programmatic printer control and data management. The platform distinguishes itself through its comprehensive automation and extensibility capabilities. It supports event-driven workflows that automatically execute cust

This project is an implementation of the Arduino framework for ESP32 microcontrollers, providing a core that enables firmware development using a familiar API. It functions as a microcontroller hardware abstraction layer and a firmware toolchain integration, bridging external development environments to the hardware for compilation and flashing. The system includes an embedded real-time operating system wrapper to manage multi-core execution and task scheduling, alongside a wireless communication suite for TCP/IP networking and Bluetooth Low Energy. It distinguishes itself by providing an obj

MissionControl is a suite of management utilities designed for pairing, configuring, and managing third-party Bluetooth controllers on a gaming console. It functions as a controller manager, hardware configuration tool, and input remapping utility. The project features a Bluetooth identity spoofer that overrides the host adapter name and address, allowing controllers to be shared across multiple devices without repeating the pairing process. It also provides a translation layer to redirect physical button presses to different logical system inputs. The software covers hardware configuration

tmk_keyboard is keyboard firmware for AVR and Cortex-M microcontrollers designed to handle key matrix scanning and HID communication. It functions as an embedded hardware control library for managing GPIO pins and EEPROM storage, as well as a driver that transmits keystroke and mouse data to a host computer via USB or PS/2 protocols. The project features a layer-based keymap engine that allows physical keys to be mapped to multiple virtual layers. It also includes a legacy keyboard protocol translator to convert signals from vintage hardware standards to modern computer interfaces. The firmw

KeepingYouAwake is a macOS menu bar utility that prevents a Mac from automatically entering sleep mode. It offers both manual and timed control, allowing users to keep their system awake with a single click from the menu bar or for a user-defined duration that automatically reverts upon expiry. The utility distinguishes itself through battery-aware operation, automatically disabling sleep prevention when the battery level drops below a configurable threshold to conserve power. This combines with a lightweight menu bar interface that provides instant activation and deactivation of sleep preven

OpenCat-Quadruped-Robot is a development framework and motion control API for building four-legged robots. It provides a comprehensive environment for quadruped robot development, featuring tools for locomotion gait design, inverse kinematics, and a layered control architecture that separates high-level intelligence from low-level motion. The project distinguishes itself as an embedded AI deployment tool, allowing users to train, quantize, and deploy machine learning models to vision modules for tasks such as object detection and visual target tracking. It further supports complex human-robot

Rhubarb is an automated lip sync generator and phonetic speech analyzer that converts audio recordings into timed mouth-shape animation data. It identifies sounds and syllables within audio files to map them to specific visual mouth shapes, serving as an animation timing exporter for external character animation software. The tool utilizes a language-independent phonetic recognizer to process speech regardless of the spoken language. To increase accuracy, it supports dialogue-guided recognition by using external text files to guide the phonetic analysis of specific spoken scripts. The system
