A Better Robotic Arm with an Innovative Hand

project report

We set ourselves the goal of building a robotic hand that can pick up small objects with odd shapes. After an extensive internet search we found a suitable approach for building such a superior robotic hand - a balloon filled with ground coffee. Initially, we mounted it on a robotic arm assembled from Lego, but as this was to weak we soon replaced the arm with a stronger wooden structure. This allowed us to grab and lift small and light objects, however, it was still not strong enough for lifting heavy objects. Therefore, we spent part of our holidays building a metallic robotic arm at a metal construction company in Euskirchen. Our new and improved robotic arm can grab and lift light and heavy objects.
