This article presents a comparative analysis of the precision of two DIY 6DOF robotic manipulators: a current model and a newly developed construction. The objective of the study was to evaluate and quantify the positional accuracy and repeatability of both designs. Both manipulators are lightweight (under 13 kg) and designed to handle payloads of up to 5 kg, making them suitable for installation on a mobile rover platform. The systems are primarily intended for teleoperation. Precision was assessed through experimental measurements, reflecting realistic operating conditions. The study demonstrates measurable improvements in the new design’s precision and provides a foundation for further development of manipulator systems for mobile, teleoperated platforms.
