Since Parkinson’s disease is a common disease which affects more than ten million people worldwide, plenty of research has been done on self-stabilizing tableware, but it was noted that they are quite expensive. A self-stabilizing spoon can retail from upwards of 200 USD without including the various additional attachments. The main aim of this project is to develop a low-cost self-stabilizing spoon for people with Parkinson’s to enable them to feed themselves. This project discusses the different approaches taken in the development of the existing assistive devices in the market as well as the design and development process of making the final self-stabilizing spoon prototype. The purpose of this project is to reintroduce a degree of normalcy back into the lives of patients by providing them with a device that enables them to eat on their own without needing external help. The final design of the prototype consisted of a BNO055 sensor, used to detect the spoon’s orientation in space and any displacement in the x, y and z axis also known as, roll, pitch and yaw caused by the hand tremors with 90% accuracy. The data is then processed by an Arduino Nano which rotates two servo motors to counteract the tremor movements. A PID controller was used to aid in the counteracting process. The prototype also comes with a mobile Application which is used to collect and store the tremor data measured on the spoon for monitoring of the patient’s condition and the progression of their disease.

摘要

Since Parkinson’s disease is a common disease which affects more than ten million people worldwide, plenty of research has been done on self-stabilizing tableware, but it was noted that they are quite expensive. A self-stabilizing spoon can retail from upwards of 200 USD without including the various additional attachments. The main aim of this project is to develop a low-cost self-stabilizing spoon for people with Parkinson’s to enable them to feed themselves. This project discusses the different approaches taken in the development of the existing assistive devices in the market as well as the design and development process of making the final self-stabilizing spoon prototype. The purpose of this project is to reintroduce a degree of normalcy back into the lives of patients by providing them with a device that enables them to eat on their own without needing external help. The final design of the prototype consisted of a BNO055 sensor, used to detect the spoon’s orientation in space and any displacement in the x, y and z axis also known as, roll, pitch and yaw caused by the hand tremors with 90% accuracy. The data is then processed by an Arduino Nano which rotates two servo motors to counteract the tremor movements. A PID controller was used to aid in the counteracting process. The prototype also comes with a mobile Application which is used to collect and store the tremor data measured on the spoon for monitoring of the patient’s condition and the progression of their disease.
