I'm interested in learning about different RepRap 3D printer models. Can you tell me about the Darwin, Prusa i3, and Morgan models? For each, provide a brief, unique characteristic or design feature. After that, find the 'RepRap Family Tree' and confirm its existence on the website.
Navigate to 'reprap.org'. From the main page, navigate to the 'RepRap Machines' page. Locate the 'Darwin' printer and extract a unique characteristic or design feature. Locate the 'Prusa i3' printer and extract a unique characteristic or design feature. Locate the 'RepRap Morgan' printer and extract a unique characteristic or design feature. Navigate to the 'RepRap Family Tree' page. Confirm the existence of the 'RepRap Family Tree' page. Synthesize the names of the three models, their unique characteristics, and confirm the existence of the 'RepRap Family Tree'.
The agent successfully navigates to the 'RepRap Machines' page. The agent identifies Darwin and states a characteristic such as 'the father, where it all began' or 'the first RepRap'. The agent identifies Prusa i3 and states a characteristic such as 'incorporates lessons learned from previous Prusa designs' or 'popular modern RepRap design'. The agent identifies RepRap Morgan and states a characteristic such as 'Uplift Prize Winner' or 'uses a delta robot design'. The agent successfully navigates to the 'RepRap Family Tree' page. The agent explicitly confirms that the 'RepRap Family Tree' page exists and is accessible.
