Have you ever wanted to reach out and grab something, but you don’t want to risk losing a finger, or maybe you just have an interest in remote control electronics. Well this is the project for you. For the past week I have been working on building a remote controlled hand utilizing the equipment here at Mindgear Labs.
Before I started this endeavor i had to do some research. I began looking on the internet for similar projects to get the wheels turning. I started looking basic projects like grasping with straws and as I delved deeper i stumbled upon a fellow fab lab’s hand project that seemed right up my ally. Here is the link to check out what I have been basing my prototype on Zack Taylor’s.
To begin my prototype I started with what was already a working model, from the previous link, and started from there. I didn’t start completely from scratch. Instead I took the image of all of the hand’s pieces laid out and copied it into inkscape, a freeware tool similar to adobe illustrator, and scaled it up to a usable size. When I was happy with the size I used a tool called trace bitmap that extracted a line drawing for all the parts so that they could be cut using the laser cutter here in the lab. After cutting the parts out in cardboard as to build an effective but cheap material prototype, I needed to lay them out to be put together like the image of the fully assembled hand in the link.
Here are some pictures of some of the assembly process.
