Electric Self Propelled Shoe : A shoe mountable last mile personal transportation vehicle

Sammanfattning: The purpose of this work was to investigate how a last mile-transport vehicle can be constructed around a shoe. The prototype, which is controlled without a handheld controller, was designed to propel an adult forward with the use of an electric driveline. The user can easily stop driving, and instead walk short distances without removing the prototype. Research questions have been answered regarding how the battery and motor can be configured to reach a top speedof 15 km/h and a range of 3 km. In addition, answers were given as to how a user should control the vehicle’s speed in a safe and simple way, without the use of a handheld remote controller. The results show that the prototype reaches the specified top speed, and that the specified range is reached and exceeded. The user controls the motor power by moving their weight from the left to the right foot. The applied weight is measured by load cells under the heel, and after calibration, this user input method can be seen as satisfactory. The electric driveline, which is mounted under the shoe, allows the user to walk short distances without removing the prototype. Future work may add safety equipment such as lamps and a bell to make the product legal for use in public areas. In addition, a left shoe needs to be developed further, due to how the concept is dependent on it to function optimally.
