Sheffield Formula Racing (SFR) is a student-lead team from the University of Sheffield. We design and manufacture a car every year to compete in the Formula Student UK (FSUK) competition which is held at Silverstone every summer. At the last competition we became the champions of the Formula Student UK. The competition was founded by IMechE in 1998 where students from across the globe compete in a series of static and dynamic events to become overall champions. This competition aims to develop "enterprising and innovative young engineers and encourage more people to take up a career in engineering". There are many other international Formula Student competitions which the team are also hoping to attend in the future.Our website and social media can be found here:http://www.sheffieldformularacing.co.uk/Instagram: @sheff_racingFacebook: Sheffield Formula RacingMore about the team can be found in our newsletter on our website.The R&D (Research and Development) and electronics sub-teams have been working hard on refining the electronics so that they are as compact and reliable as possible. This is more easily achieved by manufacturing the circuits using custom printed circuit boards.In particular, R&D sub-team have been designing and developing a system to measure the force from the aero package that has been designed for the car so that the theoretical design principles for it can be validated. The system uses strain gauges which will measure the strain on the supporting structure for the wheels. This will need to be modified to accommodate strain gauges. The current design for this can be seen below:The system uses a Wheatstone bridge where the strain gauges are connected within a bridge of resistors allowing a differential amplifier to amplify the difference in voltage between the strain gauge being stretched and a dummy strain gauge connected on opposite sides of the bridge. With the use of filters and other amplification circuits we are able to receive a 0-5V signal which can be measured using an ADC (Analog to digital converter). We have chosen a 16 bit ADC so that we have a much higher measuring resolution. This is then sent to an Arduino which is able to store the values allowing us to plot the change in downforce on the wing package on the car. With the use of an accelerometer, we are then also able to compare the measured force (or read value from the ADC) to the speed and acceleration of the car.We have been using a program called LT Spice to digitally model the circuit using its predicted response to be able to develop the schematic as efficiently as possible without wasting resources. This has also allowed us to verify that we have constructed the circuit correctly as when an oscilloscope is used, the response should be similar to that of the program which is calculated mathematically and plotted within the program to show the voltages with respect to time.We have been working on developing the circuit from a breadboard to a development board which should allow us to reduce circuit noise and increase the reliability of the circuit. These two aspects are crucial because the difference in voltage before it is amplified is very small ( <10 mV). We would like the circuit to be transferred to a circuit board as many components will be needed because 4 strain gauge setups will be required on the car.

Presentation ULYSSE is a project led by three future engineers from IPSA (Institut Polytechnique des Sciences Avancées) a French “Grande Ecole” specialized in aerospace engineering. More precisely, the project is backed by AeroIpsa, a rocketry association within the school we are members of. The Team For the last 25 years, AeroIpsa had designed, built and launched sounding rockets into the French airspace. Each year, members propose new projects and gather in teams to build it from scratch, From the CAD models all the way to the composite manufacturing, electronics soldering and programming. At the end of the year, the association takes part of the C’Space event, in partnership with the French space agency (CNES) to launch their rocket in a safe environment. During a week, teams from all around the world gathers in the South of France to finalize and qualify their rocket for launch. For more information about AeroIpsa and its projects, do not hesitate to visit our website www.aeroipsa.com (in French but with nice pictures) The Project To understand why, we first need to understand the environmental constraints of the C’Space event. First, the rocket launch site is held in a military test range covered by bushes and trees. Such amount of vegetation makes it very hard to identify any remains of a rocket once it returned to the ground. Second, once a rocket is airborne, there are two options : either the rocket deploy their parachutes and return safely to ground (nominal flight) or for some reason the parachute does not go off as planned and the rocket is now a ballistic projectile which will hit the surface of the Earth very hard (ballistic flight). Those constraints make it very hard for the teams to retrieve their rocket, and consequently the results of their main experiment, since most of these rockets do not include any telemetry system. ULYSSE is our response to tackle this issue. In order to give the teams the ability to retrieve their rocket, we designed a small (3cm high), strong and independent electronic module, able to survive an 800 meters ballistic crash and provide essential data to the ground crew such as inertial measurements and GPS coordinates. The module will feature: · GPS antenna· 9-DOF IMU· Barometer· Temperature sensor· SD card· 868MHz LoRa telemetry· And more … The idea for this module is to be “rolled” around the rocket engine, between two fixed rings and reused after each flight on any other rocket using the standard Cesaroni Pro-24 solid rocket booster. In order to build a reliable product, the PCB has been designed to use the latest Rigid-Flex PCB technology. Rigid-Flex PCB DesignMechanical Drawings PCBWay We’d like partnership with PCBWay in order to obtain their expertise on the PCB manufacturing technology and make this partnership long lasting for the AeroIpsa association and its projects.

Our projectEurobot is a European wide competition of autonomous robots. It is a 4 day long competition, taking place each year in La Roche sur Yon, a small town in west of France. 200 European teams meet each other during 100 seconds long games. At the end, the team who scored the most points wins.This year, the main theme is based on sailing activity. As accomplished sailors, the robots will have to create some fairways using beacons represented by green and reds ecocups, but also deploy a lighthouse element external from the robot.Game area of the 2020's Eurobot CompetitionThe TeamWe are a team of engineering students from INSA Strasbourg (National Institute of Applied Sciences of Strasbourg) who takes part in the French Cup of Robotics each year, qualification step for Eurobot 2020 (have a watch of our after-movie from the 2019 competition below). We come from different horizons (Electrical Engineering, Mechanical Engineering, Mechatronics, Architecture, Plastics Engineering,...) and are not supported by teachers. We design and build our robots during our free time.The Eurobot participation isn't our only activity along the year. As we know that the future generations will live with an increasing robots' presence in their own lives, we participate to some introducing events in order to sensitize children to sciences and robotics (Science festival, Hour of code festival, ...).Our team surrounding the year's game area, that allow us testing our robots in competition's conditions !Technical details of our main solutionThe strategy and trajectories are decided by a Raspberry Pi 3, that could be seen as the "brain" of our robot. As a human brain, the Raspberry Pi 3 is linked to a vision system which is materialized by an integrated camera. An OpenCV based program finally analyze the environment of the robot to make moving decisions.Routing view of our 2020's motherboardThe Raspberry Pi 3 then communicates with the motherboard, on which a dsPIC32 is embedded. The dsPIC32 is assuring the enslavement of the robot by PID position's control of the motion motors. This micro-controller also control the different actuators by communication to the other subsystems cards. 3D model of our 2020's motherboard Indeed, we opted this year for a subdivided electronic scheme. That's why we have build some extras cards, such a PCB controlling the 3-axis scara arm used to catch ecocups, and an other PCB controlling the actuators and sensors used to organize the ecocups' storage inside the robot. This cards are both embedding an ATMEGA 328p and communicate with the motherboard presented upper. We used similar cards last year to control 6 arms with vacuum pumps and color sensors to catch the atoms on the game area.The last card aims to control the lighthouse deployment and lighting. The design of this PCB is thought for a well integration in the deploying system and allow the control of power LEDs for better lighting.The mechanical pieces are laser cut in wood and some others non functional pieces are 3D printed. The integration of our PCBs is thought in order to optimize the space cost but also to have an easy access to electonics during debug phases.CAD model of our robotWords to PCBWayWe chose a few years ago start working with PCBway to fabricate the different PCBs included in our robots. We were never disappointed by the quality of the PCBway's realizations and delivery times. For this reasons, we want to entrust the realization of our cards to PCBway this year again.As our team is progressing each year in the main ranking of the Eurobot competition, we aim to access the final rounds this year ! Our experience in mechanics design assure us making a robust basis for our robot. A large part of our team is also working on strategy's code in order to still improving the performances of our moving and obstacle avoidance code.View of the robotic team's stand in the organizations' day of our engineering schoolWe offer great visibility to our sponsors during the competition, where hundreds of young engineers and future professionals visit the stand looking at our robots. We also present our sponsors during events throughout the year around Strasbourg, where we present our association, activities and robots.Our current sponsors also include RS Components, IGUS, RF Conception, the Student Association of our school, ...ContactFacebook : https://www.facebook.com/clubrobotiqueinsastras/Instagram : https://www.instagram.com/club_robot_insa/

DESCRIPTIONHi, I'm Alberto, a student mechanical engineering at University of Padua, Italy.I have to graduate soon and my final project is a system that everyone can use to make electric conversion.Actually there are no ready made complete project from motor to controller.TECHNICAL DETAILSI'm using all open source design, from motor to controller (the most expensive part).My kit would be made by two PMSM motor (130kw each) and two indipendent IGBT controller.Soon would be available GitHub page for:- Plasma cutting for motor laminations- Motor design- Igbt design- Inverter building and drivingI'm not good in electronics as it should need for this huge project (specially in safety rules), so I found and I will use ready made designs, like this one from Powerex to drive my massive IGBT modules.For this reason I would like to use the original design that is on four layers and it has tiny vias.I hope that PCBWay can help me. I've already use your service (I will also use for my self designed circuits) and I found it excellent, but the boards I bought were only two layer and with regular holes.I notice you have no shared project, in "Electic Vehicles" section, my project will also help to to be more complete.Regards,Thank you!

We are a team of student onrolled in a French Engineering school IPSA, passionate about space field. Our organization Aero-ipsa, has build over 40 rocket since 1992. Each year, we offer our member the opportunity to take part of ambitious projects, to learn beyond the scholar lectures, to work in teams with others students or companies. Since 2016, we have the ambition to create this experimental rocket, which will be launched in July 2018 during the launch compaign competition organized by the french aerospace agency.The main objective of the rocket is the deloyment of a glider module at the culmination point after separating the lower stage. The rocket is made of two different parts. The first stage is the propulsion part, ejected while the second part transforms into a plane.The electronic case will be composed of several pcb with sensors and actuators to control as many parameters as possible such as Roll, Yaw, Pitch. While, the mechanics and the pcb are produced we are developping our own telemetry system. We would like to thanks PCBWay to sponsorise university projects like ours. By doing so, you are helping student being innovative and ambitious.With your support, we are confident to be able to build rocket for the futures competion in France or in Europe. We thank you very much for your invaluable support !

### DESCRIPTION ( Introduce yourserlf and your project)I am a French student in electrical engineering. Since my 15 years old, I often practice and learn electronics by myself.I am interested in audio power amplifier for a long time, and now I would like to conclude a long personnal project about this. I have built my audio power amplifier, but a part is missing. After solving several problems, one stays currently unsolved, and your sponsorship could help me.### TECHNICAL DETAILS (With project photos)The power supply of my audio audio power amplifier is made of toroidal transformers. There is a phenomenon called inrush current that creates a transient current when power supply is turn on and this can reach around a hundred of amperes. This damage the expensive input capacitors and the diode bridge over the time.To solve this problem, the principle is simple : the current flows across limiting resistors for a second, and then a relay shorts them. This circuit is called a soft start.It is a little part of my global project, but essential.Below a photo of my first amplifier used to do some measures of performance. Since, I have learnt much things, and the board have become bigger...and better !### Words to PCBWayThanks to PCBWay to give to me and everybody a chance to realize our project ! :)

We take part of the French Cup of robotics in May 2016 and will be present in May 2017. The French cup of Robotics is a challenge of robotics towards teams of young people enthusiast of robotics.This meeting allows many dialogues of knowledge and know-how between students. We have to do independent robot, which must respect the rules. This robot has to do many actions like retrieves ping-pong balls. Community Introduction with related Community activity photos: The association, regrouping 42 members, is a part of a school composed of 1600 future engineers. (School’s website: www.insa-strasbourg.fr). We are a non-profit association; we realize all events in favor of our sponsors. During the year we organize educational meetings with middle and high schools from the area and we are present during the open doors of the INSA of Strasbourg.We will be present, as last years, at ? Fête de la Science ? in Strasbourg from the 14th until the 16th of October 2016. PHOTOS Project Introduction We have to do an independent robot for the French cup of Robotics. Each year, we received new students in our association; also we have to learn the bases of electronic, mechanic and computers. Simultaneously, our year begins with the arrival of new members. Our team offers many tutorials to learn the electronic, mechanic and programming bases. Project Details FRENCH CUP OF ROBOTIC This robot has to do many actions like retrieves ping-pong balls. The Subject of this year is: The moon. Also, we will have the rules on October, and will begin the project. Each year we work in 3 parts: mechanical, electronics and programming. Last year weredoing this program: First of all, we begin the mechanistic conception in order to design the fairing. During the design, the electronic conception is being created correlate to the programming. We used microcontroller PIC and ATXMega to realize each action: management of movement, captors, actuators and power. The communication was done by a Raspberry Pi 2, asmaster of communication in SPI. TRAINING SESSION During the training session newcomers achieve little robot name “James”, it follow a line and stop the mechanism when it touch an opponent. The electronic card has been prepared in advance, also newcomers soldered electronic elements and debug electronic card. Concurrently they prepare the mechanic design in order to print pieces on 3D. Finally they program the microcontroller.
