How do you use a robotic arm?
Imagine if your arms were as cool and powerful as Iron Man's, what would you want to do? Maybe when you drink coke, you don't need to pull the loop, just poke a hole in it with your finger. And, you won't be afraid of fire, you can easily pick up very hot food, it sounds like some science fiction, isn't it?
In my opinion, the invention of the robotic arm is the greatest good news for the disabled people. They have a chance to return to normal life. Even people with congenital disabilities can try the feeling of the right arm. From this aspect, the development of the manipulator is what many people expect.
The mechanical arm is mainly composed of joint (provide rotation or linear movement, determine the freedom of the arm), link (joint, the skeleton of the arm), drive (power, common motor, hydraulic or pneumatic system), controller (to receive instructions and control the drive, usually implemented by a computer or microprocessor) and end actuator (tools installed at the end of the arm, claw, torch, to perform specific tasks), general mechanical arm can capture action by sensors, make the same gesture by algorithm, this is the most basic operation. And robotic arms designed for the disabled can be rooted Act accordingly according to the user's wishes.
Robotic arms can accurately control the movements of human arms by various technologies. Common methods include electromyography (EMG) sensors, inertial measurement (IMU), optical tracking systems, force feedback sensors, and brain computer interfaces (BCI). The myoelectric sensor detects electrical signals of muscles that recognize movement intention in d, and the IMU uses accelerometers and gyroscopes to measure arm movements and optical tracking The system acquires arm position and posture. The force feedback sensor detects force or pressure applied by a person via a camera or an infrared sensor. Also, the BCI indirectly controls the rob arm. Optics are performed with brain electrical signals. These techniques often combine numerous fusion and advanced algorithms based on hms (e. g., machine learning) to improve the recognition accuracy of m. Action. Robotic arm motion detection technology is used for medical rehabilitation Tion, industrial cooperation and other fields and virtual reality, co help amputees restore arm function, help workers accomplish complex tasks, or enhance interactive experiences in virtual reality.
An online blogger lost her palm. By training the muscle memory on her arm, she can use the mechanical arm to make the actions she wants, and even feed herself grapes! According to the blogger, this arm captures EMG signals. Its core is connected to each finger, and two electrodes in its inner cavity capture the movement frequency of the residual limb muscles, thus forming instructions.
It is not difficult to find that if the technology of artificial intelligence achieves more breakthroughs in the future, it may be difficult to distinguish real hands from fake hands, so that there will be more happy people in this world and a lot of disagreement will be reduced. This may be the great thing about mechanization in this era!
