Master linear Kalman filtering and sensor fusion. Tune process noise Q and measurement noise R, monitor Kalman Gain K(t) convergence, simulate GPS dropouts, and inspect dynamic 1σ, 2σ, and 3σ error covariance uncertainty ellipses contracting in real-time.

Interactive visual node graph builder and tick simulator for robotics decision making. Design Sequence, Fallback, Parallel, and Decorator trees with live Blackboard state mutation and Nav2/Manipulator presets.

2D multi-robot collective intelligence simulator. Reynolds flocking forces, leader-follower formations (V-formation, Convoy, Ring, Grid) with virtual spring-dampers, distributed Laplacian consensus, and live telemetry.

Motor & Gearbox Sizing

Calculate required continuous torque, peak stall torque, wheel RPM, and mechanical wattage based on vehicle mass, wheel diameter, incline angle, acceleration, and rolling resistance.

Battery Runtime & Power Budget

Model total system current draw across microcontrollers (ESP32), single board computers (Jetson/Pi), sensors (LiDAR/Camera), and drive motors. Calculates real-world runtime and verifies C-rating safety limits.

Interactive PID Tuner & Sandbox

Real-time step-response canvas simulation with dynamic sliders for Kp, Ki, Kd and derivative filtering. Includes one-click classic Ziegler-Nichols, Pessen Integral, and No-Overshoot auto-tuning rule presets.

Mobile Robot Kinematics

Analyze differential drive and Ackermann steering kinematics. Computes forward & inverse wheel velocities, instantaneous center of curvature (ICC / ICR), and maximum cornering limits with live 2D motion canvas.

ROS 2 Command & QoS Cheatsheet

Interactive ROS 2 Humble & Jazzy command reference: CLI utilities (topic, service, action, bag, param), QoS compatibility matrix, DDS network discovery, and CMake/Python build boilerplate.

Linux Systems for Robotics

Interactive Linux engineering generator: persistent hardware symlinks (udev), autostart recovery services (systemd), hard real-time latency tuning (PREEMPT_RT), and motor networking (SocketCAN).

Starter Kits & Download Center
