RoboticsStudio

A lightweight, drag-and-drop robotics simulator powered by MuJoCo.

Why does this exist?

Industry simulators like Gazebo or Isaac Sim are built for an ideal world with perfect, expensive hardware. But students and hobbyists usually work with cheap $3 servos that have gear backlash and noisy sensors.

RoboticsStudio is built for reality. It is a plug-and-play environment where components are pre-configured to behave like the flawed, budget hardware you actually buy. Instead of spending a week configuring ROS to test a simple PID loop, you can just drag, drop, and script. And because it is a lightweight C++/Qt app, it runs flawlessly on a standard 8GB laptop without needing a dedicated GPU.

Key Features

• Visual Assembly: Drag and drop pre-configured components (Servos, IMUs, structural parts)
• Component Library (.rsdef): Mapped real-world hardware to MuJoCo using a simple JSON (.rsdef) schema.
• Script Control: Write simple, non-blocking JS coroutines to control actuators and read sensors (with arduino like syntax).
• Live Telemetry: Built-in multi-axis graphing to visualize raw input and output data as it happens.

Scripting: Just like Arduino

You don't need to learn a massive API. If you know how to write basic Arduino code, you can simulate your logic here.

let servo = comp_1;  // from scene tree
let imu = comp_21;   //        "

function loop() {
    let accel_x = imu.read_accel_x();

    if (accel_x > 2.0) {
        servo.write_angle(45.0);
    } else {
        servo.write_angle(0.0);
    }

    delay(100); // arduino equivalent delay()
}

Getting Started

Download the repo and run the build script run.sh

git clone https://github.com/alfaiajanon/RoboticsStudio.git
cd RoboticsStudio
./run.sh

Contributing

RoboticsStudio relies on community components. If you have mapped a real-world sensor, motor, or structural piece to an .rsdef file and tuned its real-world errors, please open a Pull Request to add it to the standard library.
