Autonomous Earth Moving Equipment: Like Something Out Of A Movie?

“Open the pod bay doors HAL!” "I'm sorry, Dave. I'm afraid I can't do that." In the classic 1968 movie 2001: A Space Odyssey, astronaut Dave Bowman asked the eerie supercomputer HAL to open the ship's pod bay doors and let him back inside. HAL refused, showing us to be careful of artificial intelligence evolving beyond human’s ability to control it.

How Hydraulic Flow Control and Components Regulate Speed

Hydraulic fluid power is created as the pump pushes fluid through the system. The fluid is routed through valves that direct the flow and relieve pressure when required. The fluid actuates the cylinder, resulting in hydraulic energy converting into mechanical energy. 
This begs the question: Does a hydraulic pump create pressure or flow?

How to Fix Leaking Hydraulic Fittings

We often think our hydraulic hose is leaking because it’s defective or there’s a crack in the line. Both situations are possible, but not as frequent as using the wrong hydraulic fitting type or installing them incorrectly. Plus, if there’s a missing or damaged O-ring, or if the fitting is over/under-torqued, the seal will not align properly. If the fitting is not torqued correctly, the threads can be damaged-- which is even worse, as damaged threads will definitely leak.
