Here you can read about some of the work that our team has done in the 2024/2025 college year.
the Geec’s wheel speed:
Third year Electrical and Electronic Engineering student Chrislyn Forde investigated the Geec’s wheel speed. The wheel speed sensor is a crucial addition to the Geec car’s Data Acquisition system, providing accurate real-time measurements of wheel rotation. This data helps determine speed, acceleration, and braking performance, which are essential for optimizing efficiency and improving race strategies.
More testing on the integration sensor.
Wireless Live Telemetry:
Third year Electronic and Computer Engineering student’s Lexine Nathania Estremera and Isra Yousiff worked on the Geec’s live telemetry. The objective of this project is to implement a wireless live telemetry system and a new wheel speed sensor to enable real-time monitoring of the Geec car’s performance during races. This ensures reliable and accurate data collection for analysis and optimization.
The wireless live telemetry system is designed to transmit real-time performance data from the Geec to a remote system for monitoring and analysis. This allows engineers to track critical parameters such as battery current, motor current, and voltage while the car is in motion, improving race strategy and performance assessment.
The videos below show testing for both transmitting and receiving ends for our wireless live telemetry project.
Lexine oversaw the receiving end of the transmission, managing data processing and visualisation for both real-time and historical race analysis. For web application testing, she uploaded previous race DAQ data, stored in a comma-delimited text file, to a Firebase database using a Python script. The Angular Web Application then read the streamed data in real-time, displaying sensor readings such as battery current, motor current, battery voltage, and motor voltage on graphs. This process enabled effective monitoring and analysis of race performance data.
In the video above, you can see how Isra oversaw the LoRa radio transmission testing for sending data, such as battery current and voltage, wirelessly. The process involved transmitting sensor data from the Geec’s Data Acquisition (DAQ) device through a CAN bus module to a radio transmitter. This transmitter then sent the data wirelessly to a receiver connected to another laptop, where the values were displayed in real-time on the Arduino serial plotter. The successful transmission confirmed the reliability of the system for live telemetry and race data analysis.
