Overview

Ti5 ROBOT CRA-RI50-70-PRO Motor is a lightweight joint module designed for robotic joints and integrated actuation. The module is described with “small size, powerful performance” and “core hardware breakthrough key,” and features integrated modular construction.

Key Features

  • Lightweight joint module design.
  • Ultra-lightweight: “Reduce weight by more than 1/3”; “Greatly reduce operating energy consumption.”
  • Stronger performance: “Industrial-grade performance standards”; “Torque density is twice that of similar products.”
  • Modularization: “Six modules are integrated organically”; “Three series comprehensively adapt to customers in different scenarios”; “Greatly reduce production difficulty, improve production efficiency.”
  • Mass production / platform notes (as stated): “Industry-leading mass production advantage.” “All of the underlying hardware can be controlled, and the localization rate can reach 100%.” “Owns a complete software toolchain for robot development, helping to accelerate research and development.”
  • Exploded structure labels: Motor back cover; Control board; Encoder; Stator housing; Motor rotor; Motor stator; Harmonic reducers; Flexspline cover.
  • Torque density comparison chart text: “Comparison of torque density of mainstream joint products (Nm/kg)” with labeled values: 250+ (Ti5 Robot Next Generation), 254 (An American brand), 192 (Ti5 Robot mass production model), 80.4 (A Chinese brand), 53.5 (A Canadian brand), 33.8 (A Korean brand).
