‘Terminator’ Arm is World’s Most Advanced Prosthetic

 

The bebionic3 by RSLSteeper is a carbon-fiber myoelectric hand which is also made from aluminium and alloy knuckles. The bebionic3 moves by responding to muscle twitches in the upper arm. The prosthetic limb uses sensors to trigger one of 14 pre-programmed grips that mirror common human hand movements.

The sensitivity is programmable, allowing the user to touch type on a computer keyboard, handle fragile objects like an egg and even use a computer mouse. Below you will find additional information on this remarkable device along with images and an amazing video that demonstrates the bebionic3’s capabilities.

The bebionic3 Prosthetic Limb – Key Features

 
– Individual Motors in each finger allow you to move the hand and grip in a natural, coordinated way. The motors are positioned to optimise weight distribution – making the hand feel lighter and more comfortable.

- Powerful microprocessors continuously monitor the position of each finger, giving you precise, reliable control over hand movements.

- 14 Selectable grip patterns and hand positions enable you to perform a huge number of everyday activities with ease.

- Proportional Speed Control gives you precision control over delicate tasks, so you can pick up an egg or hold a polystyrene cup as easily as crushing an empty can.

- Selectable thumb positions and a built-in sensor enable you to complete more tasks than ever before.

– Auto grip means no more accidents, as bebionic3 automatically senses when a gripped item is slipping and adjusts the grip to secure it.

- Foldaway fingers provide natural looking movement, and flex when you brush past people or bump into objects.

- Durable construction and advanced materials makes bebionic3 strong enough to handle up to 45kg – so you can confidently use the hand to carry heavy objects, and push yourself up from a seated position.

- Innovative palm design protects bebionic3 from impact damage, and makes the hand quieter than ever.

- Soft finger pads and a wide thumb profile maximises the surface area, and enhances grip.

 

 

 

The 14 Grips of the bebionic3

 
Tripod: When the thumb is opposed, the hand closes into Tripod Grip with index and middle fingers meeting the thumb. Ring and little fingers continue to close until they meet resistance or the close signal stops. This type of grip allows users to pick up, hold and manipulate a variety of everyday objects such as car keys, coins, jar lids and pens.

Pinch: To achieve this grip it is necessary for the thumb to be manually repositioned by the practitioner/technician so that the thumb only contacts the index finger. The thumb only contacts index finger and is used for the fine manipulation of objects.

Power: With the thumb opposed, all four fingers close into the palm until they meet resistance or the close signal stops. When fingers are approaching a fully closed position, the thumb drives in to cover the fingers for additional grip security. This pattern allows round objects such as a ball or a piece of fruit to be held securely. This grip can also provide a handshake. Cylindrical shaped objects such as bottles, home & garden utensil handles are also held easily and securely.

Active Index: With the thumb opposed Active Index Grip will grasp the handle of an object with the middle, ring and little fingers and secure the grip with the thumb. The index finger will then close – this may be positioned over the lever of the device held such as a spray bottle. The index finger is under independent user control and may be positioned accordingly.

Key: In the non-opposed thumb position, the four fingers partially close. The thumb then closes onto the side of the index finger. The thumb position may be raised and lowered without moving the other four fingers allowing for release, capture or reposition of the object being gripped. This pattern is ideal for carrying paper or letters, using a spoon and for holding a thin flat object such as a plate, a credit card or a key.

Finger Point: With the thumb in the non-opposed setting, the user can move to a Finger Point position. The middle, ring, and little fingers close against the palm and the thumb moves against the middle finger. With this grip, typing on a keyboard or input pad, pressing a bell or a button can be achieved.

Column: This grip moves the thumb into the palm from a non-opposed position. The fingers then close over the thumb to provide a fixed column that can be used as a way to push heavier objects or larger buttons and switches. Column is also the recommended grip for dressing, as the thumb is kept out of the way.

Mouse: With the thumb non-opposed, the thumb and little finger close to hold the side of the mouse, with the middle and ring fingers providing stability. The index finger closes on to the mouse button and then backs off to provide the button press. Each close signal will give a mouse click whilst an open signal will release the mouse.

Precision Open: To achieve this grip it is necessary for the thumb to be manually repositioned by the practitioner/technician so that the thumb only contacts the index finger. With the thumb opposed, the index finger meets the static thumb allowing the user to pick up and manipulate
small objects. When this grip is selected and a close signal is applied, the thumb closes to the midpoint of its range and pauses. The index is then active and under user control. The middle, ring and little fingers remain extended.

Precision Closed: This grip can be used in situations similar to the Precision Open Grip but where extended fingers would be obstructive, when working at a desk for instance. Initially the middle, ring and little fingers close into the palm. The thumb moves to the midpoint of its range and pauses. The Index is then active and under user control.

Hook: With the thumb in opposed, a partially closed Power Grip gives the Hook Grip. This is ideal for carrying a shopping bag or briefcase.

Finger Adduction: The fingers of the bebionic hand move together naturally as the fingers close. This allows the user to securely grip thin objects, such as cutlery or a toothbrush, between the fingers to achieve function in a different plane. Finger Adduction is most functional with the hand in Power Grip but can also be achieved with the hand in Key and Pinch.

Open Palm: With the thumb in the non-opposed position the hand may be fully opened to provide a flat palm suitable for carrying a tray or a plate.

Relaxed Hand: The thumb is set to the non-opposed position and partially driven in toward the palm. All the fingers are driven to a slightly flexed position. Applying a further signal will drive the fingers into a carrying position.
