Alicia-D Six-Axis Desktop Robotic Arm Series Overview
Product Overview
The Alicia-D series is a line of six-axis desktop servo-driven intelligent robotic arms launched by Synria Technology, designed specifically for educational and research-grade applications. It is a cost-effective, ideal platform for reproducing embodied-intelligence imitation-learning algorithms (ACT, Diffusion Policy, VLA, etc.).
Key features:
- High-precision six-axis arm design: 6DoF (7DoF including the gripper), 650 mm working radius, ±5 mm absolute positioning accuracy, ±2 mm repeatability
- Advanced motion-control algorithms: Built on Synria's in-house RoboCore robotics library as the underlying foundation, supporting joint position control, end-effector pose control, drag teaching, PID tuning, and a complete set of zero-point calibration tools, delivering smooth and efficient motion control.
- Complete SDK and ROS support: Provides a Python SDK and ROS1/2 source code
- Flexible teleoperation and teaching capabilities: Ultra-low-latency, high-speed teleoperation plus an ergonomic trigger-button leader-arm design
- AI algorithm support: Integrates with Lerobot, providing ACT, DP, and VLA open-source algorithms as well as VLM voice-control examples
