Low-Cost Prosthetic Hand

Approx. component budget: Rs. 9,000 - 15,000

Objective

Build a low-cost prosthetic hand and measure its grip force, grasp types and closing speed.

What you will build

A 3D-printed hand with tendon-driven fingers, servo motors or a linear actuator, a button or EMG input, and force sensors in the fingertips.

Results you can expect

• Grip force vs actuator torque
• Grasp success on 10 everyday objects
• Closing time
• Weight and cost comparison

What you will learn

Biomechanics, finger mechanism design, actuators and sensors, and assistive technology.

Tools and notes

3D printing, Arduino, servos, force sensors. A prototype for learning only, not for clinical use.

Resume points from this project

• Built and tested Low-Cost Prosthetic Hand; objective: build a low-cost prosthetic hand and measure its grip force, grasp types and closing speed.
• Measured and analysed grip force vs actuator torque and grasp success on 10 everyday objects; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
