JOVA Robotic Prosthetic Arm is a high-technology, user-friendly prosthetic system with added mobility and function for upper-limb amputees. The system incorporates a 3D-printed prosthetic hand on the affected side with control acquired through a motion-sensing glove on the patient’s residual hand. The glove has advanced sensors that track the movement of hands and fingers and translate this to corresponding motion of the prosthetic hand through wireless transmission. The intuitive, natural control system is seamless and simple to use without the need for surgical implants or complex calibration. With the technology of 3D printing, the prosthetic hand is light, affordable, and accessible to more people. The system is highly dexterous, strong in grip, and versatile, allowing users to do different daily activities, from grasping objects to making precise motor movements. Moreover, the module-based design makes it simple to repair and upgrade, allowing users to enjoy long-term utilization.
