The Fashionstar Star-Arm Viola Violin is a compelling, pre-assembled 7-degrees-of-freedom (7-DOF) robotic arm kit that offers an accessible entry point into robotics education and experimentation. Designed as both a leader (Violin) and follower (Viola) arm, this kit allows users to explore demonstration-based learning, offering robust functionality and real-world applicability.
This Robot arm is way different from the WAVEGO Pro Robot dog, which is based on ESP32 and Raspberry Pi, with multiple features.
Short overview:
A key feature is its ability to carry 300 grams when the arm is reached out to about 70% of how far it can go. This makes it great for doing real-life picking up tasks and for use in classrooms. The system is engineered for accuracy and reliability, with excellent positional precision to support repeatable interactions.
The kit works smoothly with top robotics systems like Hugging Face’s LeRobot, ROS 2, and MoveIt2. With these systems, users can handle learning by demonstration, inverse kinematics, and simulation, providing a complete set of tools for today’s robotics building. Also, the kit is designed to work well with NVIDIA Jetson devices, allowing artificial intelligence to run directly on the device for edge AI uses. There is a Python software development kit (SDK) for making custom automation and development easier, and the robotic arm can be connected to well-known simulation settings like Gazebo.
A unique “button hover” feature enables the arm to maintain its position after pressing a button, effectively simulating gravity compensation and simplifying data collection workflows. The modular end effector design further invites DIY customisation, making it easier to adapt the arm for specialised tasks.
