As a step forward in the design process, now we have to make the prototypes to see which works better. So we started with the prototyping. We took MDF board for our first prototype. As we started with the process, we soon realized that MDF is not the material for the final model we have to use something rigid like wood. So the flaws we found in our first prototype are that the spring which we thought of using is too hard to stretch. Secondly, the joint was too weak to take the load of that spring. Thirdly, it was hard to connect the two pieces of the prototype with a hinge. The place was too less, which ended up making the joint weak. Another flaw was that we have to place the springs at more distant places. The most difficult part of the prototype was to place the hinge because we couldn’t use screw because the end was too thin that it broke the MDF, so we decided to stick it with Araldite( a strong adhesive ). We also have to think about how we have to attach that with the body.
