How to make the robot hand

How to make the robotic hand

Here is an image of which the 3D model we are making is based on. To make this we are using a program called “3D Studio Max”. To start we made a cylinder using the create tool.

Next, I created another box using the box modelling method and placed it on top of the cylinder, as so;







To continue I created a rectangle and placed it on top of the cube. I changed the size so that it fits in the cube, this is called extrusion modelling which is a very basic tool and I had no problems with it.

To change the model, for example if you want to stretch it and make it bigger, you would use the vertices (also known as co-ordinate geometry) X,Y,Z,  X=horizontal, Y=vertical, Z=depth. The vertices are a simple method of modelling but I did have trouble with them at some points. Vertices also are used to move the model.  

I did have problems with this, for example, sometimes they wouldn’t move the way I wanted them to. The vertices are useful because you will not end up with the model in the wrong place.    



Now I created a new rectangular box and placed it on top of the other one I have created. I adjusted it as shown below:



Select the edge tool and select all the way around it except for the front. Afterwards select the box next to the chamfer tool. Adjust it as shown;  

Now create a cube and place it on the end of the new rectangle.

  

Now select the new cube and turn it into an editable poly and click on the vertex, which allows you to edit the lines and curves to change it into a different shape. Adjust the shape as shown below;   

Now create a small cylinder and place it as shown below;

Copy the cylinder and place as shown below.

Now adjust the new one as shown;

Now attach them using the attach tool.

Create a new cylinder and place it as the screen shot demonstrates.

Attach it to the bottom as shown;

Create a box and place it as shown below;

Now go on the edit poly and select the vertex tool. Also, if you press F3 you will enter wireframe mode, which allows you to see only the wire that make the shape, this allows you to edit it and see what you have selected, this way you don’t make mistakes. Wire frame helps you edit the points with more accurately.



Edit the shape until you get it like this;

Attach it to the bottom part.

Create a new cylinder and place it into the shape.

Rotate and adjust the cylinder as so;

Change to edit poly and select the vertex tool and connect the two top curves.

Then go on the edge tool and loop it and then chamfer the line. Then bring out the two lines. 

Using the vertex tool, edit the lines you do not need. Then go back on the edge tool.

Select one half and stretch it out, then do the same to the other side.

Using the vertex tool adjust the shape until it looks like this;

Now create a sphere.

Now go onto edit poly and select the vertex tool and delete the first vertices.

Select the border tool and cap up the holes and then bring it out like so;

Using the select polygon tool , select half of the sphere and detach it, select detach to element. 

Select the element tool and pull them apart.

Place them at the end.

Now adjust the model as so;

On edit poly select the end edges and create two segments.

Now select the rotating tool and change the shape as so;

Do the same to the other shapes as shown below;

Now select the bottom box (note, the box is different because I made too many mistakes on it)

Now turn it into an editable poly and select the edge tool and select the two sides as shown below;

Use the connect tool to create a line segment. Adjust it as shown below; 

Do the same to the front and back but create two. Adjust them as shown below.



Select the vertex tool.

Adjust the shape as shown by selecting and bringing in the corner curves.

Now select the element tool. The element tool affects the whole shape, so you can clone it or edit it. The element tool is useful

because when your objects are attached you can still edit parts of it.

Hold shift and bring the shape up, so you copy the object. Select clone to element.
