Did you know that there are over 25 muscles that work together to move the fingers and thumb on our hand? This may not be the same for an artificial hand such as a 3D printed robotics hand but it can function the same. With the help of our motor driver solution kit in a robotic hand application we can mimic the movements of a human’s hand.
The 3D robotic hand has actuators in the finger joints to control a gripping movement. The hand is controlled using the LV8548MC Motor Driver from our rapid prototyping motor driver solution kit, along with the included baseboard, Arduino Micro, and ON Semiconductor’s motor driver API library. This system runs off a 12V power supply and uses less than 1 amp of current when active.
With flexible sensors inside a general purpose glove that feeds an analog voltage back to the Arduino it is able to sense movement from the hand. In each of the robotic fingers are feedback potentiometers that let the Arduino know what position each finger is in. By taking the difference in flexion between human fingers and robot fingers, we can activate the linear actuators in the hand to move the joints in the fingers to simulate natural hand gestures such as picking up a ball, or pointing a finger.
The LV8548MC is used in industrial applications, as well as consumer applications such as home appliances, water pumps, fans, and printers. For more information on our line of Motor Drivers, or our rapid prototyping motor driver solution kit, please visit our website at www.onsemi.com.
