Modeling, Animating, and Rendering a Robotic Arm in Autodesk Maya

This assignment details the creation of a robotic arm model and its animation within Autodesk Maya. The process begins with project setup and folder organization, followed by the modeling phase using primitive shapes like cubes, spheres, and cylinders, employing techniques such as extrusion, bridging, and edge loops to achieve a hard-surface finish. Pivot points are centered for proper object manipulation, and materials are applied using shaders like Blinn for specularity control. Rigging involves using joints with IK to control the arm's movement, establishing parent-child relationships for hierarchical organization, and restricting unnecessary attributes in the channel box. Camera setup includes adjusting the camera type and background color. The animation phase involves creating a turntable animation by keyframing the model's rotation. Rendering is performed using Maya software, and the final output is a video created in Adobe Premiere. The assignment also includes a list of references for further learning and understanding of the software and the project.

STARTING THE PROJECT:
Planning and setting up a project folder is the first thing that I've done before starting the project.
Setting up a proper project folder helps in better file management and keeps every asset organized.
MODELING:
I have modeled the machine (a robotic arm) using the basic primitive shapes that Maya provides us
Polygon Cube, Polygon sphere and polygon Cylinder.
All the different parts of the model is made by extruding, bridging, inserting edge loops wherever
necessary to give the model a proper hard surface finish.
Moving and scaling all the different parts to proper places is important in order to give a realistic feel to
the model.
Setting up the pivot points to the centre of the object is necessary so I selected the objects and from the
Modify menu choose the "Center Pivot" option.
I have also checked if there are any extra faces or vertices, and removed if I found any.The next step in
the process is setting up the Materials.
MATERIALS:
Select objects with similar material types, right click - Assign new material, using the attribute editor I
changed the parameters to fit the materials as per my model requirements.
For most of my objects I have assigned a “blinn shader”, as I can control the specularity better this way.
RIGGING & HIERARCHIES:
In the channel box I restricted attributed that I didn’t required by selecting the attributes , right click,
lock and hide selected. I have used a joint with IK to control the angle of the piston rod as well as the
height of the piston. And attached it to the crank object in outliner. Using the Outliner option (Window
Menu - Outliner) starting from the topmost object I started adding Parent-Child relationship, by clicking
on the child object and with middle mouse button dragging them to the Parent object in the chain. By
setting the hierarchy this way helped me organizing my model and also provided a structure for moving
the various parts of the model as if they are connected mechanically.

CAMERA:
Go to the create menu and add a camera to the scene. From the attribute editor change the camera
type to 'Camera and Aim', is having a camera aim target helps in better positioning of camera. Set the
camera aim to world center and move the camera to a position where the field of view covers the entire
scene elements. Also in the environment section of the camera settings set the background color to
black. This will give a contrast between the foreground elements and background.
TURNTABLE and RENDERING:
To create the turntable animation, select all the polygonal objects in the scene and set a key frame at
frame 1. To set the keyframe simply press the hotkey “S” now moving the slider to frame 200. Rotate
the selected object in the Y-axis at 360 degree. This will give us a complete 360 degree rotation of the
model, ranging from frame 1 to 200.
In the render settings panel, Select 'Maya software' as your render engine, Under File output section,
give a 'file name prefix' and also select an Image format (JPEG). Under the frame range set the start
frame to 1 and end frame to 200. (as we have set the frames in the time range) Now from the render
menu, select batch render, and in the batch render menu click 'Batch render and close ‘This will render
the output to the ‘image’ section of our project folder
Alternatively we can use the ‘Playblast’ option from the window menu, select the time range, (keep
using the frames 1-200) Select output format to Image and the encoding to Jpg
Keep the display size option to “From Render Settings” and hit the play blast button.
FINAL OUTPUT:
After I got the image sequence of all the 200 frames as output I used “Adobe Premiere” application to
make a video output (1280x720 pixels) H.264 in mp4 format.
