Weddell 2: Differential drive robot powered by ROS

This is a differential drive robot that's capable to autonomously navigate and localize. By the help of the Robot Operating System or ROS, developing the firmware was very easy and painless. Schematics and software will be published very soon! These are 3d printed parts I used and I also provide mask_template and base_template for you to fit/make your own sensors, actuators and, modules.
