Systematic scanning is difficult due to time-consuming per-sample testing and the high-dimensional parameter space affecting performance. To address this, we propose an optimization pipeline enabled by a novel testing robot capable of scanning DEA lifetime. The robot integrates electro-mechanical property measurement, programmable voltage input, and multi-channel testing capacity. Using it, we scanned the lifetime of Elastosil-based linear actuators across parameters including input voltage magnitude, frequency, electrode material concentration, and electrical connection filler. The optimal parameter combinations improved operational lifetime under boundary operating conditions by up to 100% and were subsequently scaled up to achieve higher force and displacement output. The final product demonstrated resilience on a modular, scalable quadruped walking robot with payload carrying capacity (&gt;100% of its untethered body weight, and &gt;700% of combined actuator weight). This work is the first to introduce a self-driving lab approach into robotic actuator design.</summary>\n    <category scheme='http://arxiv.org/schemas/atom' term='cs.RO'/>\n    <published>2026-02-24T14:41:28Z</published>\n    <arxiv:primary_category term='cs.RO'/>\n    <author>\n      <name> Ang</name>\n      <arxiv:affiliation>Leo</arxiv:affiliation>\n    </author>\n    <author>\n      <name> Li</name>\n    </author>\n    <author>\n      <name>Alexander Yin</name>\n    </author>\n    <author>\n      <name>Alexander White</name>\n    </author>\n    <author>\n      <name>Sahib Sandhu</name>\n    </author>\n    <author>\n      <name>Matthew Francoeur</name>\n    </author>\n    <author>\n      <name>Victor Jimenez-Santiago</name>\n    </author>\n    <author>\n      <name>Van Remenar</name>\n    </author>\n    <author>\n      <name>Codrin Tugui</name>\n    </author>\n    <author>\n      <name>Mihai Duduta</name>\n    </author>\n  </entry>"
