APLIKASI FLEXIFORCE PADA ROBOT PEMINDAH BARANG OTOMATIS BERBASIS MIKROKONTROLER AVR ATMEGA 8

Robot is an electromechanical system having the capability in doing dirty, dull, dangerous or inaccessible tasks since robot has high accuracy, speed and never get bored nor die. Most applied type of robot in industry is arm robot, one of them is the-pick-and-place arm robot. Flexiforce sensor applied to the-pick-and-place arm robot system as weight detector and microcontroller AVR ATMEGA 8 as the controller. The output voltage of flexiforce sensor is the input of microcontroller. The sample boxes lifted by the pick-and-place arm robot are 100 gr, 160 gra and 220 gram and the arm robot choose which one to lift based on detected weight. The boxes weight are displayed in LCD (liquid crystal display). As the boxes weight detected by flexiforce sensor, the data will be inputted to microcontroller and microcontroller will instruct servo motor and gripper at the end effector of arm robot to move and pick the boxes (position limited to 135 degree). The arm robot will place the box to final position and continuously pick and place other boxes. Flexiforce sensor works based on resistance applied to it, the heavier the boxes, the bigger resistance will be and the bigger applied resistance the bigger Vout will be
