In recent months, how to create various electronic arms that help us pick up objects, move them, etc. have appeared on the Internet, something useful if we need help in our home or office. But it is true that normally these electronic arms cannot be moved from one place, at least they are not as portable as our own natural arm.
ExoArm is an electronic arm that can be carried because it is connected to our body and it works as a reinforcement for our own arm. ExoArm may seem like an electronic prosthesis but rather it is an aid or support for people who have little strength or need more strength such as older people.
ExoArm is a project Hardware Libre which uses electronics to have a useful external arm. Currently ExoArm is functional but not very aesthetic. The project uses several motors and a board Arduino UNO to create the necessary force to the user. Also, as you can see in the picture, the ExoArm covers a large part of the body. This is because rests on the back to provide a counterweight and offer more stability and safety to the user.
Unfortunately the ExoArm is not a great electronic arm and can only load with extra 10kg. A fairly limited weight for those who wish to carry large or heavier objects. In any case, ExoArm is a living project and that means that during the next updates, the exobarm will allow us to gain more weight and even be more aesthetic, a task in which they are currently more focused.
ExoArm is also an economical project, a project that has an approximate cost of 100 dollars. If you want to know the progress in this project or simply know how to build one, in the official website of the project you will find all that information. I don't know if ExoArm will really offer a solution for the day-to-day elderly, but for that price, it is worth a try. Do not you think?
