Gesture Controlled Robotic Arm For Hazardous Chemical Control

The use of nuclear energy is on the rise as it produces more power compared to fossil fuels and it does not produce greenhouse gas emissions such as carbon dioxide. However, it is very dangerous for humans and the environment when a nuclear meltdown happens. Nuclear waste takes a long time to decay and it releases radioactive in the process which is harmful to living things. A robotic arm can be used in these scenarios to move radioactive waste without human interaction. Operators can control the robotic arm wirelessly through gesture control from a safe distance without exposing them to radioactive. Gesture control is used as it enables the operator to live control the robot for different scenarios. The hand gesture-controlled robotic arm uses a wireless system to transmit data signals between the gesture controller and robot manipulator without any physical connection between the two systems. The wireless gesture controller will convey gesture movements from a real person's arm to control the robot manipulator. The proposed system uses flex sensors, ADXL335 accelerometers, and MPU6050 to capture hand gesture movements. Two Arduino Mega, one on the user's hand while the other on the robotic arm, and servo motors were used in the system. A pair of NRF24LOI+ transceiver modules are used to establish a wireless connection between the system.
