Prosthetic arms are artificial devices designed to replace a missing or non-functioning arm. They can help individuals regain some level of functionality and independence in daily activities. These devices can be customized to fit the user's needs and may include features like grips, joints, and even electronic components for enhanced movement. Modern prosthetic arms often use advanced materials and technology, such as 3D printing and robotics, to improve comfort and usability. Some prosthetics are controlled by the user's muscle signals, allowing for more natural movements. This innovation has significantly improved the quality of life for many individuals with limb loss.
