The main goal of this project is to build, assemble, and successfully test an accelerated testing machine for the India Mark II. In the India Mark II pump, the water gaskets wore off frequently during the pumping of water and needed frequent replacement which proved costly. To counter the problem, the project below proposes an accelerated testing machine composed of a slider-crank mechanism. The mechanism incorporated a flywheel driven by a motor that ensures continuous harmonic motion that replicates pumping mechanisms in the field. The mechanism was designed, simulated and a finite element analysis carried out in CAD software. These are covered in the report along with testing results and recommendations provided for improvement of future designs.​

Modern mechanical engineers utilize computers but do not fully understand how the computer performs its computations. Understanding the fundamentals will give them a better understanding to the limitation of traditional computing. To address this gap between functionality and understanding, we built a 4ft by 6ft physical 3-bit adder to blow up the tiny processes that go on inside of a computer. Using a system of logic gates, where marbles act as inputs and outputs, our machine is able to add numbers 7 and below to each other and produce an output in binary.

Robotic control is becoming increasingly integral across many disciplines and industries.

L3Harris Technologies is an American defense company that builds a variety of mechanical, optical, and electrical systems. The Rochester division designs and builds systems for space applications. Optical space telescopes are widely used in both Earth and astrophysical observations and play a major role in scientific and national security. For optical telescopes to function properly and take clear images, their optics must be precisely aligned to focus light. However, during the launch of the telescope, the relative positions of these optics can change. The goal of the project is to build a mechanism to finely adjust the position of these optics to enhance resolution and accuracy of the telescope images. This improved image quality has significant implications for both terrestrial and space observations with applications to scientific research and national security.

Our team, along with Drill Powered Carts A have built a fully functioning, energy-efficient, and sustainable vehicle, which will be powered by a single electric power drill.

The two teams will face off in an endurance race to see which cart can make the most laps around a race track at the University of Rochester River Campus. This will show which team has the most optimized mechanical design.

The goal of this project is to launch a non-spherical shape in a controlled, repeatable manner to study the impacts of low-velocity debris on the granular surfaces of asteroids. This research could potentially assist in future missions to land on asteroids by learning about the trajectories taken after initial impact and the effects that spin, angle of impact, and velocity have on those trajectories. ​

Several optomechanical applications have a need for a 360° kinematic mounting system capable of withstanding thermal loading due to heat generation from electronic devices. It is advantageous for optical systems to have a repeatable and controlled, known distance between devices such as optics, sensors, light sources, mirrors or assorted non-optical sensors. The team was able to design a thermally stable spaceframe solution, capable of reducing movement of any assembled components to minimal displacements on the order of microns.

In Syria, there are thousands of refugees that have upper limb amputations that don’t have access to function prosthetics.

The goal of the design is to create a 3D printable prosthetic that improves on the design from the previous year by making the hand look more realistic as well as improve its functionality.

Students at the Mary Cariola Center with visual impairments are attracted to light in rooms, often pulling their attention away from the teachers/lesson to look upwards at the ceiling lights. Lighted surfaces that provide contrast can help students focus on that surface and on any activity being performed on the lighted surface. The team was tasked with creating a mat suitable for children that illuminates in order to draw the student’s attention downward.

The Rossell Hope Robbins Library is underutilized by many students on campus due to the lack of awareness of the library and its resources. To promote awareness for the library, this project contains designs for a “life-size” portable chess set with medieval themes.

The project aims to design a steering system for robots used in various ECE courses. The robotic system has issues with lifetime, maneuverability, and mobility. The new model was designed with an aim to direct most of the off-axis load into the chassis while still maintaining the capability of the DC motor driving the wheel. These improvements helped in significantly increasing the lifetime of the motors. Additionally, the ability to steer each wheel independently increased the mobility of the robot.

After a nuclear accident, radiation levels must be determined in order to ensure the safety of those involved in cleaning up radioactive material. The goal of this project is to produce a low-cost drone that can be used to survey the radiation levels present in a given area, and to produce a heat map of the measured radiation. All of this data must then be transmitted at a distance where the operators will be safe from radiation exposure.

A renewed focus on environmental concerns means that fuel efficiency and emissions of engines are of significant importance. A current design for a mixing nozzle exists, but the fuel residence could be higher and the pressure drop could be lower. A longer fuel residence time ensures smooth distribution of fuel and a more efficient burn. A lower pressure drop means that less energy is lost by the motion of the fluid through the mixer.

Helmets in the NFL are not effective enough to safeguard the health of the players. Players sustain concussions which can not only bench them, but leave life-long brain damage from the accelerations experienced during impact. As part of the project to improve the helmet, simulations were used to test material properties of different components of football helmets, such as hard foams, soft foams, and the shell. Data from the simulations were analyzed with performance metrics provided by the NFL.
