Project Hand-Y - Pragyaan Submission

Hand - Y is a Prosthesis inspired Robot. It moves according to the movement of the User’s arm using the inbuilt flex module. Our aim is to basically allow the user to move the robot’s arm using the user's natural hand movements.

The Project has three parts, The Robot, The Armature Unit and a Face Detection Module

The Armature Unit is the most important part of the project. It is A Module that can be worn by the user that sends data from a flex sensor embedded in a wearable gauntlet structure that tracks the movement of the fingers to the robotic arm like structure. The shoulder mounted unit has a steel frame with a black box that contains the core of the user module, an ATMEGA AVR, present in an Arduino Uno. This Project Follows I2C Protocol, So the armature is connected directly to the Atmega AVR of the Robot, which is the robot’s motherboard.

The Robot Chassis is made out of heavy duty cardboard, which has been spray painted using a Static Electricity Principle. The arm moves due to a Stepper Motor presently connected to said arm. The Stepper Motor is connected to a CircuitBoard known as a MotorDriver, which is connected to the Atmega Avr.

Both the Robot and the Armature Unit is powered by a the coding language that is a blend of C/C#

A Standalone Camera is present in the Crevices of the ArmMount Structure, Which is connected to the CPU of a Computer via WiFi. The Computer accesses the camera using a Custom Face Detection software we built using Python. This Module Works on the HaarCascade Principle of Detection. Once it Detects a Face, it uses a software called OpenCv to draw a bounding box over the face detected. This uses Frame By Frame detection algorithm

Uses of the Project:

• Can be used for amputees (people without limbs)

• Can be used in the medical industry when a surgeon works remotely

• Can be used when fragile equipment and objects are to be used by the robot
