Robotics technology has advanced significantly in the recent years, particularly in the area of prosthetics. MIT developed a glove that provides the human hand with two extra robot fingers, and there are even wrist-mounted robots that can give the wearer additional fingers. These advancements are allowing more people to live better lives despite disabilities.

MIT’s Robot Glove


Researchers at MIT have developed a glove that features two extra robot fingers. The team behind the project refers to the addition as an “extra thumb” and claims that the technology could be a game-changer for surgery and manufacturing.

The glove is designed to sit alongside the user’s existing fingers, providing extra dexterity and flexibility when performing tasks that usually require more than five digits. The robotic fingers are not only capable of gripping objects but can also move independently of the fingers.

Wrist Mounted Robot

A wrist-mounted robot has been developed by researchers in Italy that can provide wearers with two extra fingers. The device, which is about the size of a watch, is designed to be worn around the wrist, and the robotic fingers can be deployed whenever needed.

The robotic fingers are controlled by the movement of the wearer’s remaining fingers. They can be used to hold objects, providing extra support when carrying out tasks like holding a mug or opening a jar lid.

A miniature robotic finger has been developed by SMAC, a company that specializes in developing actuators for robotic fingers. The device is just a few centimetres long and is capable of carrying out delicate movements with high precision.

The finger is designed to be used in a variety of applications, including manufacturing and medicine. Its compact design means that it can reach difficult areas, and its precision makes it an essential tool for any task that requires detailed movements.

Interacting with Insects

Interacting with Insects

One of the most unusual applications for robotic fingers is in the field of entomology. Researchers at the University of California, Berkeley, have developed tiny robotic fingers that allow humans to interact with insects.

The device is called the VelociRoACH, and it is a small, six-legged robot that can crawl around and interact with insects. It features a pair of miniature robotic fingers that can pick up small objects and move them around. This allows researchers to study the insects up close, without the need to capture or harm them.


Q: What are some of the benefits of robotic fingers?

Robotic fingers can provide a range of benefits, particularly for those with disabilities. They can help individuals carry out tasks that would usually be difficult or impossible, such as opening jars or holding objects.

Robotic fingers can also be used in manufacturing, medicine, and a range of other applications where precise and delicate movements are required. They can help to increase efficiency and accuracy, and can reduce the risk of human error.

Q: How do robotic fingers work?

Robotic fingers work by mimicking the movement and function of human fingers. They are often controlled by sensors in the user’s remaining fingers or by tracking the movement of the wearer’s arm.

The fingers are made up of a range of components, including motors, sensors, and actuators. These components work together to create movement and provide flexibility and dexterity.
