Vacuum grippers are very simple astrictive devices that can hold very large loads provided the prehension surface is smooth enough to ensure suction. Pick and place robots for electronic components and for large objects like car windscreens, often use very simple vacuum grippers. Vacuum grippers can handle a wide range of applications and are ideal for picking up uneven and even workpieces made of different materials, such as cardboard, glass, sheet metal (dry) and plastic. Your task is to enter the combination of the correct values of the required parameters, so that the robot arm successfully transfers the cube from its starting position to the conveyor belt. You need to find minimal pressure required to overcome the weight of the load but taking in the consideration that the acceleration of the vacuum gripper system may cause that the object is dropped.
Force created by the vacuum gripper should be calculated using following formula
F = ( (m * 4 * (a + 9.81) )2 + (m * 8 *( (a / 0.5) + 9.81) )2) / ( (p * 2 * 0.003) / 8)2 + ( (p * 2 * 0.003) / 4)2
Possible cases are 1. Robotic arm can not lift up the cube; 2. Robotic arm can lift up the cube, but drops it immediately; 3. Robotic arm can lift up the cube, but drops it while transfering it; 4. Robotic arm successfully transfers the cube. The result will compare total forces of cube and total forces of the vacuum gripper. It will be fun, try it!
The entered values are correct. Cube is successfully transfered. Force of the vacuum gripper is higher than the weight of the cube.
Force of the load is higher than the force of vacuum gripper.
Force of the vacuum gripper is high enough to produce lift, but not high enough to complete transfer.
Mass must bit in range 1-1000 g! Acceleration must be in range 1-10 m/s!
