This is a model of robot's arm, for researching of other planets. It can crash hard surface with it's chisel-like tool, grab pieces with three fingers and put them imto a container (isn't shown). The fingers have individual electromagnetic actuators. This allows to grab pieces of any form . The arm has one rotational joint and one slider. The rotational joint and the slider can be operated manually. The chisel has electromagnetic drive. The arm has a flange with two holes which in order to fix the arm to a robot model (e.g. VEX) with screws. I created and animated the arm 3D model with Fusion 360 Ultimate. Some parts are made with Autodesk AutoCAD 2016 and imoprted into Fusion 360. I used Fusion 360 Cloud service to render images and animation.
