There is no better way to learn robotics and improve as a maker than 3D printing and building your own robots. Vorpal the Hexapod is a 3D printable robot that you can control with a simple gamepad to complete 60 different motions. You can program it via drag & drop.
You can modify the parts to customize your bot. All the models are open source. Pretty cool if you ask us. More info is available here.
