In the project we use the controller placed on top of the ankle in combination with a sensing system located on the bottom of the foot. The purpose of the project is to allow the amputee to move the robotic arm in a comfortable and easy-to-use manner. The product we developed communicates with the arm via wireless Bluetooth communication. Identification of a command sent to the arm is carried out by tapping the heel, tapping the toe and leaning to the sides. In response the arm opens, closes and rotates. The product was designed for all users and is adjustable for different body weights and foot sizes, a calibration is performed at the beginning of each use, which lasts about 30 seconds and aims to adjust the recognition of the commands to the consumer.
