Bio-Signal Processing

Processing technologies
that accurately analyze the body’s movements

Bio-signals are the electrical signals passed through nerves in the human bodies that allow us to move our limbs and allow our brains to receive information from our senses. We need to be able to receive and process these bio-signals in order to make cyborgs move, but existing technologies simply weren’t accurate enough to process the diverse movements of the human body. The unique bio-signal processing algorithm that MELTIN has produced, however, allows for highly-accurate real-time analyses of these movements. As well as being able to accurately distinguish between an open hand and a closed fist, it can also process “scissoring” motions with the fingers, as well as bending and extending the thumb and bending the wrist. In total it can process 12 types of complex movements as needed. It can also distinguish between adjacent muscle movements, as well as composite motions such as “Bending fingers while twisting the wrist”. All of this allows for intuitive control of cyborgs in a way that requires no special training.

Robot Mechanisms

The most human-like technology in the world,
inspired by living organisms

In order to create the hand movement mechanisms, we thoroughly researched the human body, in particular the structure of muscles and tendons. We landed on the concept of MELTANT-α itself through the idea of directly copying the human hand.
MELTIN has reproduced the complex finger movements in a wire-driven manner. The hand we produced is able to perform power-varied actions such as holding an egg without cracking it, picking up and holding a laptop, and shaking a 500 ml drink bottle containing a liquid. These strong and delicate movements would never have been possible using traditional robotics but have been reproduced here in a form that is the same size and weight as a human hand. There are no previous examples of a technology like this anywhere else in the world. It is a completely new technology that reproduces traits unique to human hands such as delicateness, dexterity, and strength, while still maintaining the same form factor as a hand.
