These are video tutorials for designing and constructing durable, reliable and stable LEGO Mindstorms constructions. Both the EV3 and the NXT robotics sets are used. We prefer to show the construction along with the process of how we engineer it, re-engineer and how we come to the final solution. 

You could also find robotics tutorials about constructing robot attachments. During each FIRST LEGO League, World Robotics Olypmiad and other competitions based on LEGO, the attachments more than important.
