A.2.9 Steering Committee: An advisory committee usually made up of high-level stakeholders and/or experts from various supporting agencies, organizations institutions etc. who provide guidance and direction on key issues such as policy and objectives, budgetary control, marketing strategy, resource allocation, and decisions involving large expenditures. A.3 Overview of Event A.3.1 Event Objective: The SAEI-OHB TIFAN Event challenges teams of undergraduate engineering students to conceive, design, fabricate, develop, and compete with implement-based farm machinery, in an event with field demonstration. This engineering event gives teams the maximum design flexibility and the freedom to 6 Public express their creativity and imaginations, however there are very few specifications or requirements on the overall machine design as explained in this rule book. A.3.2 TIFAN 2025 Theme: The TIFAN 2025 Event is designed to evolve around the theme of challenges in Vegetable Transplanting and thereby the theme chosen for this year is “Automated Multi Vegetable Transplanter”, For Chili, Brinjal and Tomato saplings. Teams are expected to conceive, design, develop and demonstrate a working level prototype of a farm machine at the specified venue following all the requirements mentioned in this rule book. The very design objectives of this Event are as below. i. The teams are to assume that they work for a design firm that is designing, fabricating, testing, and demonstrating a prototype of tractor mounted automated multi vegetable transplanter for a new and emerging market. ii. The Machine should have good performance in terms of productivity, coverage, damage to crops, cleanliness of crop, operator comfort, and safe to the operator as well as bystander. It should be sufficiently durable to successfully complete all the events described in the TIFAN Event rules. iii. Once the Machine has been completed and tested, your design firm will attempt to “sell” the design to a fictitious “company” that is considering the production of Automated Multi Vegetable Transplanter. iv. Each design will be judged and evaluated against other competing designs to determine the best overall Transplanter. v. Machines entered to TIFAN Events are expected to be designed and fabricated in accordance with good engineering practices by the engineering students without professional help. vi. The team which has participated more than a year and qualified for the final event will be called as old team. vii. Teams are also encouraged to explore addition of features, enabling the machine’s utility for transplanting Chili, Brinjal, Tomato saplings.

B. PART B: TECHNICAL REQUIREMENTS AND REGULATIONS B.1 Phase 1 - Preliminary/Qualifying Round The SAEINDIA TIFAN Qualifying Round is a filtration criterion, through which all the registered teams are evaluated for their knowledge and capability to participate successfully in the field /main event. Depending upon guidelines and competent approvals, the Organizing Committee will decide the main event (Physical Round) to be conducted and will be communicated in due course of time. The Qualifying Round for TIFAN2025 will be conducted through Digital platforms only. There is no requirement for any team mates to be together. Digital platforms such as Microsoft Teams, Google meet, Webex, etc. will be utilized to conduct this Event. The exact details of the same will be communicated. Student teams are encouraged to get acquainted with these tools to have smooth execution of Qualifying Round. Teams need to submit the presentations / reports in the template provided by TIFAN OC and in given timelines for respective rounds of evaluations. Late entries will have a penalty. For the qualifying round teams will be evaluated based on the below two criteria’s, 1. Design review Presentation: The presentation template will be uploaded to the SAE TIFAN page by the end of July. The key points to be addressed are outlined at the conclusion of this section. 2. Functional Prototype / Simulation of Pickup System: Returning team - A functional pickup system prototype is needed for the virtual event. The prototype can be a scaled version created using 3D printing or basic sheet metal components. It could be motorized or, as a last resort, manually powered with potential penalty points. The objective of requesting the prototype is to focus teams on building a functional pickup system and give them early experience in integrating motors and controllers with mechanical components. New team - new teams are advised to create the prototype as per the requirements for returning teams but it is not mandatory.
