&lt;hr>
&lt;p>A joint research project between Tongji University&amp;rsquo;s Sino-German Industry 4.0 Lab and Siemens, replacing legacy particle swarm optimization (PSO) with deep reinforcement learning for higher-precision robotic arm control.&lt;/p>
&lt;p>&lt;strong>Technical work:&lt;/strong>&lt;/p>
&lt;ul>
&lt;li>&lt;strong>DQN agent&lt;/strong> for joint trajectory optimization, replacing PSO baseline&lt;/li>
&lt;li>&lt;strong>Three.js 3D visualization&lt;/strong> — interactive slider-based parameter control, real-time model updates, importable industrial equipment scenes&lt;/li>
&lt;li>&lt;strong>SITP project certification&lt;/strong> completed&lt;/li>
&lt;/ul>
&lt;p>&lt;strong>Key insight:&lt;/strong> After exposure to NVIDIA Isaac Sim, identified that the core need is not model import/visualization but custom algorithm interfaces and GPU-accelerated physics simulation — pivoted research direction accordingly.&lt;/p>

&lt;p>The steering system uses a &lt;strong>cam-based mechanism&lt;/strong> to convert rotational motion into precise lateral displacement, eliminating the need for servo actuators and improving mechanical reliability. The drivetrain uses a gear reduction stage paired with brushed DC motors.&lt;/p>
