      <description>Working on LLM-powered task planning, exploring VLA models, and building a sim benchmark.</description>
      <content:encoded><![CDATA[<h3 id="building">Building</h3>
<p>Working on LLM-powered robotic task planning systems that translate natural-language commands into executable ROS2 action sequences for simulated manipulators. The goal: making robots that can take verbal instructions and turn them into safe, verifiable motion plans.</p>
<h3 id="learning">Learning</h3>
<p>Exploring diffusion-based robot policies and vision-language-action (VLA) models — particularly how they can replace hand-coded task planners in unstructured environments. Also getting deeper into Isaac Sim for large-scale sim-to-real workflows.</p>
<h3 id="reading">Reading</h3>
<ul>
<li><em>Probabilistic Robotics</em> — Thrun, Burgard &amp; Fox (finally finishing it)</li>
<li>Recent papers from CoRL 2025 on world models for robot learning</li>
<li><em>The Art of Doing Science and Engineering</em> — Richard Hamming</li>
</ul>
<h3 id="side-project">Side Project</h3>
<p>Building a small robotics simulation benchmark for evaluating LLM planners across a variety of household manipulation tasks — dishes, drawers, object sorting. Planning to release it as open source.</p>
<h3 id="location">Location</h3>
<p>Currently based in Tehran, Iran. Open to remote research collaborations and freelance robotics engineering work.</p>

      <title>ROS2 Simulation and System Log</title>

      <description>A short log entry covering ROS2 simulation updates and system observations.</description>
      <content:encoded><![CDATA[<p>Today I tested the ROS2 planning stack in Gazebo with a simulated manipulator. The robot completed the pick-and-place behavior, but the controller still needs a tighter feedback loop for fine-grained placement.</p>
<ul>
<li>Added a new <code>lifecycle</code> node for state management.</li>
<li>Logged delay spikes from the joint trajectory action.</li>
<li>Verified collision boundaries in the simulator.</li>
</ul>
