Our battery design has come a long way from last year’s competition, with main advancements relating to BMS data recording and case modularity. The cell model we have chosen to use is the HG2 from LG. It boasts a high continuous discharge current of 20A, as well as a high capacity of 3Ah. In pursuit of a high efficiency, this year we have made the switch from a 48V system to 36V, changing our battery arrangement from 13S4P (13 cells in series, 4 in parallel) to 10S5P, allowing us to in ...
Our powertrain development team is responsible for creating all electrical aspects of the drive system in our electric prototype vehicle. The team is made up of a series of development sub-teams tackling distinct modules which come together to provide the full working system, each of which serve a specific purpose. Each module consists of a blend of custom firmware and hardware which must be designed, built and tested by each development team.   Logic Board The most obvious of these is t ...

In the first part of this topic, we showed the process that lead us to the sizing and configuration of our battery pack. In this post, we are going to go through the process of adapting that batterypack to the motorcycle, how the first version of battery containers were designed and produced.   The changes made in the design of the accumulator container and consequent changes in other parts of the electric system such as the BMS were made with the objective of simplifying integration of th ...
        One of the hardest part (at least for us) of building an electric motorcycle is the development of the accumulator and respective container. The sizing of the battery is not the only problem, designing a safe and simple wiring method, and containers for the batteries that comply with the safety norms of Motostudent regulation, and at the same time actually fit all of that plus electronics inside the frame of a motorcycle is quite difficult as well. This is the story o ...

Introducing Avalon's ROV

Posted by khaled63 Jul 15, 2018
Testing and development Throughout the project we have experimented with a variety of designs and prototypes to arrive at the ideal design for the missions that we have. A good example of this is the actuator that we have designed to balance a platform by rotating a PVC pipe connector. The initial design can be seen below. While this design was able to accomplish the task, it was not efficient because it tended to slip (you can see it in action in the video below). To fix this problem, we desig ...
Would you like to see this IoT proposal developed further? Head over to our University IoT Challenge voting page to help this project get turned into a reality.   Modern agriculture applications necessitate cheap, low-maintenance and low-cost wireless telemetry for various environmental parameters, such as environmental humidity, soil moisture, barometric pressure, and temperature. Continuous and dense environmental monitoring is critical for optimal crop and water management techniques an ...
Would you like to see this IoT proposal developed further? Head over to our University IoT Challenge voting page to help this project get turned into a reality.   1. Executive Summary An IoT-enabled hearing protection solution is proposed, and a novel device will be developed based on this solution. This implementation will bring together digital signal processing (DSP) noise cancellation technology, Bluetooth connectivity technology, smartphones, traditional hearing protection technolog ...
E.ffective L.one L.ifestyle A.ssistant   Would you like to see this IoT proposal developed further? Head over to our University IoT Challenge voting page to help this project get turned into a reality.   The principle concept of E.L.L.A. is to offer the long term housebound (through illness, disability, dementia etc.) a voice-controlled assistant to help them to continue to lead their own lifestyle for as long as physically possible.   By combining already existing voice, vide ...

PetBud - May Update

Posted by __ryanmcclure May 11, 2018
So far a few problems with regards to setting up the board have been encountered, these are discussed below:   Challenges In order to setup and configure the WaRP 7 board there are an array of procedures involved which can vary in their stages dependant on what software and computer you are using. We first tried to get the board configured using MAC OS Sierra, however, it proved to be troublesome using this host machine setup. This was due to a few issues surrounding the configurability b ...
TLMoto is a team of students from Instituto Superior Técnico, Lisbon, Portugal. Our main goal is to build a fully electric motorcycle to participate the Motostudent International Competition, which happens every two years in the Motorland Aragon MotoGP Circuit.   Our team was created in 2012 and competed in 2014 in the Petrol category (as there was no electric category at the time).  Now, we are building our first electric Motorcycle and will participate this October in the Mot ...
The team has been hard at work during April with the focus on preparing the robot for testing very soon. We made some great progress on the electrical system and the manipulators.   Electrical Updates Having received the PCBs and the electronic components from Farnell, earlier in April, the electrical team started assembling the custom boards.   The first of these boards is the Communication Board, which is responsible for all interfacing between the Microcontroller and the Surface Com ...
    BACKGROUND   As part of our embedded system class project at the Ulster University we undertook some market research to see if any new avenue of innovation could be found aside from what is currently available for the smart feeding of pets.   Existing smart feeders are monitored and controlled via a software application on a smartphone with set feeding times and schedules. These feeders are purely 'semi- automatic' and are somewhat reliant on the owner. It was found b ...
We are a team of multidisciplinary engineering students from the University of Sheffield, participating in the MATE ROV Competition. This is a competition to design and build an underwater remotely operated vehicle (ROV) to carry out missions based on real-life problems. Each year, there is a new theme, which the missions are based on. For example, in 2016 the missions were based on the use of ROVs on other planets and moons, such Jupiter’s Moon Europa, and the competition took place in NA ...
We’ve been running our own summer school for many years now, and over the course of these years we’ve learned a lot of details about running them. Robotics summer schools present their own unique challenges which might not be obvious from the start. Our hopes are this post will help those who haven’t had any experience running a summer school, and want to follow in our footsteps and run their own robotics summer school.   Student knowledge At the start of the event, you ca ...
