How to Make #Arduino Gloves Your Droid Will Love @Device_Plus_en #WearableWednesday
We’ve seen plenty of gloves, but these by Ivan Petrov show the degree of movement in each finger and thumb, allowing the wearer to get specific about commands. There’s a lot going on here, so Ivan has created a tutorial that covers how to use the hardware before incorporating it into the gloves. Here’s his description of the project:
The Arduino-based acquisition system is located on each hand of the user. The Arduino board gets flexion of the fingers (finger bending) by measuring the resistance of each potentiometer. Orientation of the user’s hand can be defined after processing data from inertial measurement unit (IMU), which includes gyroscope and accelerometer. Battery and wireless data transfer allow this Arduino-based acquisition system to be used as a wearable smart glove. For example, this could be used as a universal input device to manually control a robot arm.
The main parts include an Arduino Uno, a wireless shield, potentiometer, resistor, an IMU Sensor and Bluetooth Bee. I like that he explains each piece, especially the rotation section, complete with equations. So often people skip the math in tutorials, but it’s nice to know how the electronics work. Ivan takes us as far as the Bee connection, so we are going to have to wait to get the juicy details about glove implementation. In the meantime, if you are interested in doing a build like this, you can start by checking out our 9-DOF IMU Breakout learning guide. You’ll learn how to capture nine different types of motion/orientation data and discover the connection to robotics. It’s all about hands-on experience!
