A great milestone was achieved this past Saturday, when the barebones telemetry system was successfully tested in Azure. The radio, snooper/data logger, and battery monitoring system worked just as well in the car under driving conditions as they did on the bench. Radio range was tested to have already surpassed that of Azure’s, and the front-end graphical user interface which records and graphs the collected data performed very smoothly. From here on, new modules including accelerometers and the driver display will be added to telemetry and the whole system will undergo performance and safety optimization to ensure that our 7th generation vehicle will have the first fully working telemetry system in Blue Sky history.
On the power side of things, a new motor control setup is being tested. Saturday saw forward acceleration and regeneration braking in action, with reverse and cruise control to be added in the coming weeks. The power being drawn by the motor controller was not where we would like it to be, and tweaks will be made to overcome this. Optimization of this power system will give us a much better idea of how we should set up the new one.
Alongside our testing, the old NGM brushless DC motor which acted as the backup on the last race will be characterised this week in preparation for design of the new power system. More on that next time!
