Development of modular Electrical Power System for KuupKulgur prototype
(Tartu Ülikool, 2025) Lindmaa, Laur Edvard; Tartu Ülikool. Loodus- ja täppisteaduste valdkond; Tartu Ülikool. Tehnoloogiainstituut
CubeRovers are a new class of lightweight, modular robotic platforms designed to lower the barrier to lunar surface exploration. To support such systems, a reliable and modular Electrical Power System (EPS) is essential. This thesis focuses on the development of an EPS for KuupKulgur, a CubeRover prototype created at Tartu Observatory. An advanced EPS-v2 was designed to meet a comprehensive set of power and communication requirements. While EPS-v2 serves as the foundation for future implementations, a simplified EPS-v1.1 was subsequently developed based on lessons learned during the design of v2. This version was tailored to enhance the reliability and performance of the current KuupKulgur rover prototype. The work includes the design, prototyping, and testing of both EPS boards. All system requirements were fulfilled, with the exception of hot-swappability, which was deprioritized due to mechanical and reliability constraints. Although space qualification was beyond the scope of this thesis, the system architecture allows for potential future thermal-vacuum and radiation testing. The results presented here lay the groundwork for future EPS revisions compatible with CubeRover standards and operational lunar missions.

Interface development for ESTCube-2 cameras and plasma brake
(Tartu Ülikool, 2023) Lindmaa, Laur Edvard; Tartu Ülikool. Loodus- ja täppisteaduste valdkond; Tartu Ülikool. Tehnoloogiainstituut
Conducting experiments and obtaining data is a crucial component of scientific space missions. To accomplish this, establishing reliable communication with all payloads is necessary. Nevertheless, at the beginning of the thesis, there was no integration in place to interface with the ESTCube-2 payloads. Furthermore, there was limited documentation available regarding communication with both the Earth Observation cameras and the plasma brake. During the thesis, the author created firmware for communicating with said payloads. Additionally, the author conducted thorough tests and verified that camera firmware
