The Mercury A1 from Elephant Robotics is a lightweight seven-axis robotic arm equipped with seven self-developed Power Spring harmonic modules delivering up to 80 Nm maximum output torque, 19-bit encoder resolution, and 0.6 arc-minute repetitive positioning accuracy with an ultra-lightweight carbon fiber shell. It uses a Cortex A72 1.5 GHz main controller with a 2.0-inch IPS-LCD capacitive touch screen and the myPanel OS for deployment without programming. It supports three major software operation modes and more than ten hardware accessories, with an open-source software ecosystem and mainstream programming language support.
