Project Information
"This project entails a design of an electro-mechanical gripper mechanism which can pick-up and drop off a provided payload. The main focus of this project is the application of compliant mechanism for the gripper. This makes the gripper free of any mechanical joints or hinges. Moreover, the gripper mechanism consists of only single solid body, eliminating the need for assembly, mechanical friction, and wear.
A variety of different software was used in the development stage of our project, which helped in the analysis and design needed for completion. The two components of this design are 3D printed with PLA material and mounted together using M3 Bolts. Moreover, the opening and closing motion of the mechanical gripper is powered by an electromagnetic actuator which is activated by a remote controlled electrical circuit.
Our project includes two designs: The main assemble (electrical circuit-Box) which is attached to the drone and the subassembly (gripper) which is attached to the box. The gripper design is one component which performs the opening and closing motion without additional printing of other components. The electrical circuit box is a simple design equipped with vents to keep the circuit cool. It also includes a cover which can be easily removed if there is a need for work to be done on the electrical circuit."

For our project, we have taken on the task of designing and building a dual-axis tilt rotor arm mechanismthat can be attached to a drone. On a conventional drone the rotor can either pitch on the lateral axis orroll on the longitudinal axis, however, for our prototype we set out to create a mechanism that can doboth. The design incorporates two servo motors, 3D-printed gear wheels, a ball bearing, and other 3Dprinted components. The first servo motor is responsible for spinning the gears which in tilt the wholedrone arm on the longitudinal axis. The second servo motor will push a flat plate – part of a mechanismthat converts linear motion into rotational motion – that will ensure the rotor support tilts on the lateralaxis.This mechanism will help the existing drones to develop into better technologically advanced droneswhich will have reduced size, less weight and easier to control in comparison to existing conventionaldrone. Also, the mechanism allow the conventional drone (quadcopter, drone having 4 drone arms) tobe modified as unicopter, bicopter, or tricopter depending on the application.Overall, it is a great innovation to UAV industries and would help drones to achieve efficiency both interms of weight and energy consumption

Traditionally, A glider is dependent on a tow plane to take off. Once in flight, the glider's flight time is limited by how much lift is available through utilizing natural wind currents and thermal activity. With these two liabilities in mind, our team has decided to create a foldable propeller system capable of assisting the glider with takeoff and during flight making the glider completely independent. To achieve this, we plan on using an electric motor followed by foldable propellers that will seemingly integrate with the glider, and not compromise aerodynamic flow. The engine and prop system will be located at the nose of the glider. When the engine is not in use, the propellers will align themselves correctly.

"With the recent rising revolution of unmanned aerial vehicle (UAV), our team of 3 aerospace engineers came up with a unique and innovative design of a UAV as part of the advanced aerospace project course. The design aims to reduce the required weight significantly by considering one propeller instead of the conventional four rotors. The design consists of one propeller which is designed to generate sufficient thrust to lift the whole drone and its additional payload. The drone will have the ability to control its yaw, roll and pitch through four novel airfoils, that follows the key principles of aerodynamics, actuated by four servo motors. When the airfoil’s angle of attack is changed, the propeller speed will automatically adjust its airflow to ensure its controllable altitude as the airfoils direct the airflow to the opposite direction of its target. This will result in driving the drone to fly towards the target. The selected flight controller is suitable for the application because it includes gyroscope sensor, proportional-integral-derivative feedback control for all actuators, as well as a USB-port to access and modify the flight controller’s software. The chassis of the drone makes an octagon shape with a cylinder top to serve as a propeller guard and both are attached to two-sided landing legs. The purpose of this design is to ensure its rigidly, minimal power consumption, light weight, and effective aerodynamic performance, which are the most crucial aspect to be followed in every aerospace industry including the rising revolution of UAV."

"The project that we want to present for you is a Golf ball Retriever. This is our ongoing project in Design and Construction that transfers a golf ball from one cylinder to another. Our professor gave us an interchangeable fixture where a cylinder was located at each end of the plate that is across from each other, see the picture attached below. The goal of this project is to build a mechanical assembly that uses a hand crank, timing belt and pulleys which will give a transfer motion into it. The moving part of the project (the pipe) will pick the ball from one hopper and drop it on the cylinder. A repetitive motion must be achieved without any interruption. In addition, we are only allowed to design the fixed part of the retriever on an 8""x 10"" plate that gives us a restricted area to build our design. The difficult part of this project is that the ball must always be lifted vertically when carrying it to another cylinder. As a solution, we came up with an idea of lifting the ball by using a link mechanism to convert the rotational motion into a linear motion. Also, by using a slider, we made it possible to transport the ball steadily and to have a simple structure. For this reason, manufacturing becomes easier, reduces torque loss, and transmits the proper torque to the linkage mechanism. "

"The automatic filing machine project was suggested by professor Robert Mahabirsingh and initiated for the purpose of improving the efficiency for students to file their parts. One observation we all made throughout our time working part-time in the tool crib was that we noticed how inefficient and difficult it was for the students to file their parts; therefore, an automatic filing machine would be something that was actually needed in the lab instead of just making for exhibition. The following picture shows a slider-crank mechanism; power is transferred from the motor to the slider which holds the file moving vertically. The goal of the project design is to use the simplest thing to finish the same amount of work more effectively. Moreover, it has high productivity because the systems that power is being transferred through are relatively simple and direct which means less energy is wasted during transmission. The overall weight has also been a strength of this design which makes this machine more convenient and portable. This project is designed for new-to-the-field, inexperienced students, considering this factor, a file stabilizer is designed to hold the file in case students are pushing parts using too much force. During our calculation design process, we have agreed 3 inches’ displacement is perfect for maximum efficiency of the file after analyzing the file dimension."

Our project is a scalp cooling system the main focus is to prevent hair loss during chemotherapy treatment but it could also be used for outdoor activities such as cycling. This works by applying cold temperatures to your scalp which limits the blood flow to the scalp, this prevents the chemotherapy treatment from targeting your hair follicles. For the helmet to reach low temperatures is to remove as much heat as possible on the hot side by using a large heatsink and a fan to dissipate the heat and by using a good quality peltier module will also increase the performance.

The rising interest in eco-friendly technology globally leads us in search of renewable sources of energy, specifically by wind. The power generated other than the solar panel generator works with the mechanical turbine inside of the generator. The energy source that turns the mechanical turbine determines the type of generator. For example, the generator that is turned by nuclear power is called the nuclear power generator. Similarly, the wind turbine generator is rotated by wind power in the air. Once the turbine is rotated, electricity is generated. There are several factors in determining the availability of the wind turbine. The length and shape of the air blades are considered the most important parts of this project. The length of the air blades is made long enough to get an efficient force to turn the high torque AC motor. The air foil design is adapted to the shape of the air blades. The air foil design helps to gain more wind force compared to other geometrical designs of the same length. Other than the purchased parts, most parts are manufactured with an additive manufacturing method called, 3D printing. Aluminum is used as a base plate to support the entire body.
