Technical Specifications

COVVI has an innovative actuator design which comes in three different sizes, and four different colours, all of which operate with next-generation grip force and speed. We started with the small COVVI Hand before building bigger. This ensured we did not compromise on any functionality across the size range.

Certified Quality

COVVI has achieved International Organization for Standards (ISO) rating 13485, which is an enhanced quality management system specifically targeted toward the medical device world. It incorporates a risk management approach to product development and product realization. We have also attained ISO 9001, which is an internationally recognised standard for creating, implementing, and maintaining a Quality Management System for a company

Process validation is greatly enhanced, which aids in improving the quality of the design and the manufactured product.
