Welcome to the lecture 3 of this week. We are discussing the prototyping methods and certain prototypes that we have developed here for the agriculture these are agricultural machinery. A very wonderful prototype that we had developed here is the plant seeding machine. What does it do? It transplant or it transform the seed into the sand very quickly. How does it work? We’ll show you the demonstration. So, let us assume that we have some mushy soil here in the bucket we put the seed from the top and insert the machine in the soil we put seeds from the top when we pull the lever the cone opens and the seed goes in the sand and then we pull the machine up. Now, the seed is sown. So, what does this lever pulling does? When we pull the lever you see there is the cone that is in three parts that opens and closes while using this lever. So, this is also a wonderful design. So, there certain components of this design.

First, thing is the main pipe that is a cylindrical pipe, then on the top of the pipe you can see a funnel from which we planted the seed and on the in the bottom we have the cone that is divided into three parts, and three parts of the cone we have strips, these chips are joined using wire to a ring in the center, and this ring is further joint to lever using wires, and we have a supporting rod or holder here or handle that is used to hold the machine. Now, this is also develop using in certain steps. Now, the first step further was obviously the speculation, the ideas were there, then we develop the low fidelity prototype, the low fidelity prototype for this is here. So, this is made out of a corrugated shield and you can see all the components are there in a spring action, the spring action that was there in the main component that was using wire that is being provided by rubber here. Rubber band, rubber band is providing spring action here and the core is again cut in three parts, and this is all joined using again the cellulose tape, and because you can see that the corrugated sheet is folded or is rolled to develop this cylinder, and levers, handle everything is developed using this corrugated sheet. So this is also one of the products that we have developed here. Similarly, the certain other products developed, and this is one of the very important products that we have developed and for the quick action we can just, one can just hold the seeds in the bag and this is operated by a single operator. Single  orbital can hold the seeds, keep transplanting the seeds into the soil continuously. So, this is also one of the components that we thought we should discuss in this course. So, this was a quick demonstration on the plant seeder machine.

Next we’ll discuss about the pineapple peeling machine and peanut seed separator, certain other machines that will be developed. We have discussed those quickly in the next lecture. So, this is just to give you the feel that how do we develop the prototypes, and how do we get the higher fidelity prototypes which can be taken to the product phase further. These prototypes are actually working. All these prototypes that we are showing you here are being used, are actually tested while giving to the farmers, the first-hand user, the farmers which are close to our institute they have used that, the food cutters, the fruit sellers, they have used these prototypes. So we will discussed two or three more prototypes in the next lecture.
