goBilda parts 

goBilda makes parts specifically designed for building robots. They are known for being:

Metric: This means all the parts use a system of millimeters for sizing, which is common for many robotics components.
Lightweight: The aluminum building materials keep the robot's weight down, allowing it to move faster and more efficiently.
Modular: goBilda parts are designed to work together easily, with parts snapping together or using fasteners specifically designed for the system. This makes it simple to build and modify robots.
Here are some of the core building block types from goBilda:

Channels: These are long, U-shaped pieces of aluminum that form the main structure of the robot. They come in different sizes.
goRAIL: This is a special channel with a groove on one side. It allows wheels with a flange to ride smoothly along it.
Beams: These are solid rods or square beams that can be used to connect parts together and add rigidity to the robot.
Shafts and Tubing: These are hollow or solid rods that are used for axles and other spinning parts of the robot.
Mounts: These are brackets that come in many shapes and sizes and are used to connect other goBilda parts together at various angles.
Clamping Mounts: These are a special type of mount that uses a screw mechanism to grip a shaft or other part tightly.
There are many other goBilda parts available, including sprockets, belts, wheels, and motors. These parts allow you to build robots that can move, grip objects, and sense their environment.
