Assistive Robotics

A new robotic arm is designed to be mounted on a power wheelchair to improve quality of life for individuals with limited or no upper limb mobility. Known as JACO®, it can interface to a variety of existing wheelchair controls – including joystick, sip-and-puff and head array systems – and utilizes the same wheelchair power source. It also mounts directly to the arm to minimize overall width and reach up to 36 inches (900 mm).

Six-axis movement corresponds to shoulder, elbow and wrist motion to more closely mimic a functioning arm. A two- or three-finger gripper allows users to do nearly anything that a human arm can do, and offers increased autonomy by enabling users to eat, drink and perform personal care tasks (such as brushing their teeth and hair) on their own.

The ability to pick up the phone in an emergency or leave the house if needed enhances personal security, and socialization is also increased by enabling a user to play games as well as interact more naturally with people and pets.

JACO currently lists for about $35,000, and the cost is not covered by insurance providers. However, the developer is already working on a more affordable version.
