Wireless Humanoid Bionic Arm On Robotic Vehicle
Project Area of Specialization RoboticsProject SummaryThe main purpose of this project is to control the movement of robotic arm and robotic vehicle by replicating the movement of your hands.
This system has two wireless controllers mounted on gloves, one for each hand of the operator. Here system precisely replicates the motion of one hand of the operator onto
the motion of the robotic arm. The RF receiver is interfaced with microcontroller to control the driver IC which is responsible for controlling the movement of the arm. The transmitter circuit consists of an accelerometer sensor which is interfaced to microcontroller. This transmitter circuit sends commands to the receiver circuit which indicates whether to move the robotic arm in any directions or whether to grip an
object or release it.
Also using the hand gestures of the other hand of the operator, motion of robotic vehicle is controlled.
Project ObjectivesThe main objective is to develop a hand gesture based robotic vehicle with an end effector to pick and place objects controlled by nRF communication to increase the autonomy of physically impaired people. This is an attractive and compact embedded device with sensors to sense the activities of human hands and to capture motion information from accelerations in a form of analog voltage. This approach is focusing primarily on the task of grasping objects of different shapes and not that of manipulating or assembling objects.
Also, to control the displacement of the robotic arm so that the arm can be used to pick and place objects from any source to destination.
This Project consist of two parts:
1. TRANSMITTING END
The transmitter section consists of Arduino Uno Rev3 SMD, 3-axis accelerometer (ADXL 335), flex sensor, push button switches and nRF24L01 with 2.4GHz transmitter module. A separate 5 volt power supply which may be a battery source or through laptop or pc is applied to the arduino controller. The arduino Uno, flex sensor, push button switches and transmitter module receives 5V power supply. Accelerometer takes 5V supply but a voltage regulator is inbuilt on the sensor which regulates power supply to 3.3V. The accelerometer sensor and flex sensor are attached to the user’s hand for capturing different types of gestures like movements of hand and flex of fingers. According to the movements of the hand, input is taken from the accelerometer sensor and flex sensor then the corresponding signal is sent to the controller. When the user moves his hand or finger, the sensors fixed to the hand outputs an analog voltage value. The Arduino Uno reads the analog output values i.e. x-axis and y-axis values from the 3 axis (ADXL 335) accelerometer sensor and flex sensor. The analog outputs values which were achieved by parts of the body must need to convert in digital form for further proceed. The converted digital values processed by the arduino controller. This signal is utilized for the displacement of the robotic arm and soft catching gripper.
The movement of our hands is used to drive the wheels of the robotic vehicle & Robotic Arm.
2. RECEIVING END
The receiver section consists of Arduino Uno, RElay Modules, DC Geared Motors, Servo Motor, 12V Rechargeable Battery Source, Robotic Platform, Robotic Arm and nRF24L01 with 2.4GHz Receiver Module. A separate 5 volt power supply which may be a battery source or through laptop or pc is applied to the arduino controller. The receiver module receives the modulated signal from the transmitter and demodulates it. Then the signal is fed to the arduino controller.
So by implementing above two parts we can control the movement of the car & displacement of the robotic arm so that the robot can be used to pick and place objects from a specific source to destination.
Benefits of the Project? In Nuclear Plants
They are used in nuclear power stations, welding and repairing pipelines on the ocean floor, remote servicing of utility power lines, or cleaning up radioactive and other hazardous wastes.
? Agriculture Sector:
It is very hard and sometimes even unsafe for workers to go to each plant and pluck fruits. A robotic arm fixed to a rover roams in the in orchard and the user can control it remotely using the hand glove fixed with various sensors. These sensors can position the robotic arm remotely to harvest the fruits.
? Hospital Operations:
Robotic vehicle movement and Arm control through hand gestures is also used for hospital operations to increase the autonomy of physically impaired people. It is a kind of functional replacement hand integrated with the moving vehicle that aids the amputees often suffers from physical difficulties.
? Military Sector:
It is used in military operations because of its preciseness and accuracy.It is used in critical such as or diffusing a bomb. Robotic arms could be of tremendous use to save lives
- We have created this robot to increase the autonomy of people who can’t walk & for handling radioactive materials and harmful chemicals in Nuclear Sector because People in Nuclear power plants who handles harmful radioactive materials get sick because of radiation. This robot removes the direct interaction between humans and radioactive materials.
