Remote-Control Excavator

Remote-Control Excavator Project

As the current state of industry moves towards an industrially globalized landscape, the expansion of modernized infrastructure is inevitable. This expansion, as is the case with any form of change, will have both good and bad consequences. Our goal as future Engineers is to tackle these issues head on, and to the best of our abilities deliver a product that is on par with industry standards. In the short history of mankind there has been a handful of defining moments that have shaped the world to what it is now. Some defining moments include the Bronze Age, The Industrial Revolution, the invention of the combustion engine, and the harnessing of electricity just to name a few. These defining moments are few and far between and as the world transitions to renewable forms of energy we have the privilege of being witnesses to such transition. Today, it is no secret that electricity is at the forefront when it comes to renewable forms of energy. It is also true that in our not too distant futures, our dependency on fossil fuels will be a thing of the past.As a result of these last two statements, we are beginning to enter the electric powered car revolution. which is gaining momentum very quickly, and some estimates predict that in 20 years there will be more electric vehicles than combustion powered ones on the road. As the movement grows its influence has managed to reach manufactures of heavy machinery such as caterpillar, Volvo as well as a few others. At the moment all of the electric excavators that are being prototyped and produced have applications that are most suited for professional use. Our team has been tasked with the capstone project of designing and building a small-scale, remotely operated excavator that is fully electric. The excavator’s primary application will be to dig irrigation trenches that would otherwise be dug manually. Some of the requirements that our project demand include a durable design, capable of a full 8-hour workday, and the ability to dig at minimum 6-inch-wide and 12-inch-deep trenches.

Oscar Nunez

My name is Oscar Nunez, and major is echanical engineering major. My role in our capstone project was creating the FEA model that we will use to validate and improve our design, as well as coding all of the force calculations for the project. Additionally I helped with the arm and bucket design. In the future I hope to be working either locally at W.L.Gore, or I plan to move to Washington state and pursue a career with bowing.
