Overview
ROBSTRIDE Dynamics Edulite A3 is a 6-DOF desktop robotic arm + gripper designed for ROS2/Python development, motion planning, and interactive teaching. It supports force-position hybrid control and gravity-compensated drag teaching, and integrates high-level functions such as MoveIt2 motion planning with a web-based visualization control interface.
Key Features
- Open-source, high-precision motion control: 7-segment S-curve trajectory planning + speed feedforward + multi-stage low-pass filtering for smooth, shock-free motion
- Gravity compensation: Pinocchio dynamics-based gravity compensation; complete dynamics model based on RNEA; supports automatic inertial parameter calibration (12 parameters, R² > 0.99) for precise drag teaching
- Control modes: Force-position hybrid control / Position control
- Operation modes: Xbox controller Cartesian space real-time control (50Hz / 5-speed variable); master-slave teleoperation (one-to-many / many-to-many)
- Safety protection: Singularity detection and automatic recovery; joint soft and hard limit protection; self-collision and environment collision detection
- High-level functions: MoveIt2 motion planning and obstacle avoidance; web-based visualization control interface
- Zero-torque mode: Supports gravity-compensated drag teaching and pure zero-torque master-slave teleoperation; independent joint damping adjustment
- Toolchain: One-click environment configuration; automatic inertia calibration; Foxglove remote visualization (control frequency 200 Hz); seamless switching between simulation and real robot; customizable end effector
