1.2 Basic Survey and requirements
| Observation from the Surveys | Requirements |
|---|---|
| Weight of the machine | It should be easy to carry and transportable i.e, below 2 kgs |
| Cost | Machine should be built within the budget of Rs.4000 |
| Material to be used | Materials used to build the machine should be strong enough to withstand the weight of the object |
| Number of objects to be dropped in the assembly of line | 2 Objects per minute |
1.3 Identify the Client's Objectives
| Sl.No | Objectives |
|---|---|
| 1. | Semi-automatic. |
| 2. | Portability. |
| 3. | Safety. |
| 4. | Accept the inputs from the user |
Problem definition version 1.1 : Design the semi-automatic robotic arm machine,which is portable which accepts the user inputs to pick and place the objects.
1.4 Identify Constraints
| Sl.No | Contraints |
|---|---|
| 1. | Dimensions 1000 cubic cm. |
| 2. | Machine should have 5 Degrees of Freedom. |
| 3. | The machine should work continuously for 3 hrs. |
| 4. | Cost of the machine should be less than 4000. |
| 5. | Machine should drop 2 objects in assembly line per minute. |
Problem definition version 1.2 : Design the semi-automatic robotic arm machine, which should be portable,accept the user inputs for picking and dropping the objects,The machine should not exceed the volume of 1000 cubic cms, should be able to drop 2 objects in assembly line per minute, budget to build should not exceed Rs.4000,it contains 5 degrees of freedom and the machine should work continuously for 3 hours.
1.5 Establish Functions
| Sl.no | Functions |
|---|---|
| 1. | The Base of the arm supports 360° reach around it |
| 2. | Contains a grip to safely hold the picked objects. |
| 3. | Picks objects from different directions. |
| 4. | A shoulder,elbow,wrist bends to pick and place the object. |
| 5. | A gripper of the arm can be rotated when the object is picked. |
| 6. | Have the on/off switch to operate. |
| 7. | Drop the object safely in the assembly of line. |
Problem definition version 1.3 : Design the semi-automatic robotic arm machine, which should be portable,accept the user inputs for picking and dropping the objects,The machine should not exceed the volume of 1000 cubic cms, should be able to drop 2 objects in assembly line per minute, budget to build should not exceed Rs.4000,it contains 5 degrees of freedom and the arm should pick the objects from the different direction and drop it in assembly of line,it has bending of shoulder, elbow,wrist and rotation of base to complete the process of picking and dropping.
