<h3><strong>Grobot Animations</strong> is a high-performance C++ library specifically designed for the ESP32 to bring lifelike, expressive animations to small TFT displays.</h3>

<p>I'm a fresh grad and I've been working on a DIY robot (Grobot). I really wanted those expressive "Vector-style" eyes, but I found that most existing libraries (like RoboEyes) are built for low-res OLEDs and look choppy on TFTs.</p>

<p>So, I spent the last few days building Grobot_Animations.</p>

<ul>
<li>Key Specs:</li>
<li></li>
<li>Physics-based: Uses spring damping for organic "bouncy" movement (not just linear slides).</li>
<li></li>
<li>High Performance: Hits 90 FPS at 80MHz SPI by using partial windowing and DMA.</li>
<li></li>
<li>Lightweight: Purely procedural (no bitmaps), so it barely touches your Flash storage.</li>
<li></li>
<li>Compatible: Built on TFT_eSPI for ESP32/RP2040.</li>
</ul>

Grobot Animations: Lightweight & Fluid Robot Eyes for ESP32 (TFT_eSPI)

A lightweight, spring-physics-powered animation library for ESP32 and TFT_eSPI that makes creating fluid, lifelike robot eyes as simple as a single function call.
