For my main project I aimed to create a “Cardboard Grabber”. Basically I am aiming to extend my reach, increase the surface area of my “hand”, and to retain grip strength on objects. The device would serve in Halloween costumes such as Iron Man or re-decorated to look like Hulk Hands or monster claws. In my initial designs, shown below, was a very rudimentary style of what I thought the base model would look like before I looked to improve the efficiency of the mechanics and design
The main issue I ran into working off of this design was the mechanics of the opposable thumb. With the joints along the inside of the hand like the other fingers, the sharp angle from the curve of the thumb to the carriage with the operator hand would be too great and break the adhesive. I consulted the internet to see if I could find past examples of re-created joint mechanics, and I found my solution. Showcased below in my final project schematic, The joints for the thumb go through the inside face of the hand, and out to the back face where the joints are placed.
By creating a new path for the control wire the stress was significantly reduced, and full control of the thumb was possible. Now that the joints are holding strong, the next challenge is threading the control wire through this winding path for the thumb to reach the control carriage. Once that is complete I will dive deeper into enhancing the aesthetic of the piece. I decided on the iron-man aesthetic and for the franchise fans out there, I will pursue the niche aesthetic within iron-man, the “War Machine” aesthetic. I plan on taking bullet casings and creating a set of brass knuckles on the outside face of the grabber. I will also employ sharp edged shapes to give it a sleek, dangerous look.
