Mobile Base Crane
In order to expand the teaching styles and resources of Mechanical Design, ME351, additional avenues are being explored to create a more interactive lab for students. A mobile crane can be used to teach and reinforce concepts regarding control theory, robotics, dynamics, statics and mechanical design. A crane can also be useful during outreach programs for the Mechanical Engineering Department. It is the goal of Team KRANE to design and build a device that will accomplish these goals.
The crane that UNR has at its disposal fails to meet standards that would allow for usage as an engaging teaching tool. The crane in its current form is incapable of adjustment in the radial direction, it is not lightweight to allow easy transit for usage in outreach programs or educational labs, has poor control of movement during operation, cannot adjust speed, and is of an overall dubious design with many shortcomings. It is possible to redesign a more functional and useful device for the teaching staff in the ME department.
Design requirements for our mobile base crane include to expand UNR teaching and outreach tools, true 3D movement of a payload, a lightweight system with easy transportability, precision speed and position control, and a GUI for easy use.
Proof of Concept
The product Team KRANE is developing would most likely belong in the category of educational products for understanding crane and crane dynamics. In this industry, the two main competitors would be Elenco, as well as LEGO, both companies which produce products with similar goals in mind. While Team KRANE’s mobile base crane is not intended for being brought to market, the team has analyzed weaknesses with other educational cranes and has increased the level of complexity with which the designed crane will function and what it will be able to teach. By surpassing the shortcomings of the other products available, Team KRANE’s crane will provide become a robust and flexible teaching and outreach tool for UNR to use.
Team Krane designed two different proof of concepts: tipping and motion control. The tipping concept would prove that it would take a significant amount of external force for the crane to tip over, causing a hazard. The motion control concept proves that position tracking and speed control is able to be displayed in real time and adjusted to the user’s specification.
These concepts provide valuable real-world application knowledge to get a better understanding of how the system reacts to different forces on a smaller, scaled model of the designs. This ensures that there are no major flaws in the design and provides further proof to the analysis previously performed on these models. Below are the drawings and schematics for Team Krane’s proof of concepts.
Testing and Results
Meet the Team
I have lived in Reno for 13 years now, and before my family landed here, I had moved 16 times in just 14 years. I have lived in every major region of the US except the northeast, and am happy to have settled in Reno. While attending UNR, I have been able to maintain a 3.8 GPA, and have become interested in systems and control theory. The most challenging engineering project I have been involved with was successfully writing a MATLAB code for aerodynamics last year that simulated an airfoil in a wind tunnel. The greatest engineering skill I have developed in my academic career is an acceptance that sometimes things do not work out on the first attempt. Sometimes multiple iterations are necessary, and it is okay to “fail” as long as a lesson is learned from it and implemented in the future. Outside of school and work, I am most proud of the success I’ve had with my gaming hobbies. I have travelled all over the west coast for both card games and tabletop wargames to compete in tournaments and routinely have high place, cash finishes in those events. Utilizing the knowledge I have gained in my schooling and applying it to everyday occurrences has been an extremely rewarding byproduct of my education. An example would be using my learning of newtonian mechanics and dynamics to understand certain exercises and how to improve my form in the gym to gain the most from them without hurting myself. My goal is to find employment at an engineering firm somewhere in the Reno/Sparks/Carson area and remain local, as I have greatly enjoyed this area since moving here. In the future it is my hope to use my social skills to find employment as a liason of sorts and periodically travel for work.
My name is Jeremiah Avalos and I am a Senior at the University of Nevada, Reno. I will be graduating in the Spring 2019 with a Bachelors in Mechanical Engineering. I was born in San Jose, CA and lived in Reno for the last 15 years. The most challenging engineer project that I have been involved with would be a fully automated robotic system at my current job. I have developed a hard working attitude and work ethic through the mechanical engineer department at UNR. I have engineer industry experience for developing biomedical equipment with Hamilton Company. My biggest accomplishment outside of school is my family and their support to push me through school to receive my degree. I have applied analytical techniques to determine the shaft design parameters for fatigue and stress failure with a constant load applied.
My current goals include working hard everyday to push myself through school and to support my family. After graduation I hope to remain at my current company and continue to develop my engineering career.
My name is Patrick Cendana and I am senior at the University of Nevada,Reno.The most challenging project is the time when I had to work with team in mech design class where we have a series of projects to do for that semester.It was successfully we came together worked on the projects. I developed the skill in FEA analysis on determining stress and strain on two pieces, the L-beam and cylindrical vessels. The years I spent at UNR I developed strong work habits. The motivation to obtain an engineering degree is my support from from family. I was born in Manilla in the Philippines. I’ve spent 13 years growing up in Bellflower,California in LA county. I currently live in Reno,Nevada for 11 years. My dream goal is to work for an automobile, aerospace and/or renewable energy company. My intermediate goal is to land a job in Reno because this place is beautiful. Furthermore after graduation I planned to stay local and find an engineering firm. My other option is looking for employment somewhere in the United States.
I was born and raised in the Reno/Sparks area. I started playing baseball when I was 4 years old and played all the way through my sophomore year of high school when I, unfortunately, had an arm injury taking me out of the game for the rest of my life. After baseball I turned to building and working on computers as a hobby which eventually turned into a job at Geek Squad. I recently earned my Geek Squad Agent badge for being there for 2 years. Engineering always seemed to be the path I was on. Anywhere I went I would constantly ponder how things were built or just how they worked. Fast forward to now, I am currently in the final stretch of getting my Bachelors in Mechanical Engineering at the University of Nevada, Reno. I have recently took an interest in Chinese language and the culture they have to offer in hopes that one day I can live in China doing something I enjoy: solving problems. My favorite accomplishment in academics would be passing the Fundamental engineering exam on the first go. The most challenging engineering project I’ve been a part of was at my internship with LSP Specialty Products during the summer of 2017. I assisted in automating multiple manufacturing processes for plumbing products and I learned a ton of things about myself and the way I tackle hard questions. I came out of the internship a smarter person and more humble in more own knowledge as well as more appreciative for engineers as a whole.

This capstone project is by far the most difficult engineering project I have tackled so far. I am hoping to apply all my skills used throughout my college career (e.g. FEA analysis, robotics actuator dynamics, strength and materials analysis). One of my favorite projects was for the introduction to robotics course.Using the computer vision skills developed during the lecture, I created a script in MatLab for image processing. Outside of school I like to use the skills I have learned in school to design keyboards for my personal use. Using solidworks I design a case to store the keyboard compartments and make sure the keyboard layout is ergonomic. I was born in Mexico and was raised in the Las Vegas, I moved to Reno to in 2015 to attend the University of Nevada, Reno. I am proud to be the first person in my family to graduate and attend college. After graduation, I plan to find a job and move back home to Las Vegas to help support my family.
