The document provides instructions for a presentation template to discuss the design of a machine. It outlines that teams should use the template, discuss relevant topics using bullet points and images, and customize slides 13 and 14. It also provides suggested topics to cover in the presentation, including the machine specifications, frame design, digging and separating systems, power transmission, steering, and validation plans.

1. Instructions
• Each team is required to use only this template
• Points mentioned on each slides are suggested items that could be
discussed over this presentation. Team can choose appropriate topics
relevant to their design.
• Points which are not relevant to your design can be omitted from
slides
• The font type is Calibri (body) with minimum size 18 and should be
readable and adjusted as per the slide contents
• Please do not overcrowd the slides with text only, it is suggested to
use bullet points instead of detail report. Use images/graph/picture
and voice out the details during presentation.
• Slide no 13 and 14 are to be used as appropriate for your machine
