<h3 class="sub-tit">Bumping into objects</h3>
<p class="txt-idt">1. If an obstacle is placed lower than the top LiDAR sensor, the front bumper detects it.</p><p class="txt-idt">
2. If it keeps pushing obstacles, check if the bumper works normally.<br/>
<strong>Press the bumper to check if it works normally. (Clicking sound)</strong><br/>
After opening the product, check if the protective foams at the both sides of the bumper are removed.
</p><p class="txt-idt">
3. If it keeps bumping into obstacles in the same location, set no-go zones on the ThinQ app.<br/>
You can prevent hitting with obstacles.
</p>

<h3 class="sub-tit">Others</h3>
<p class="info-desc idt">➔ Basically, the LiDAR sensor detects obstacles. If not possible, the front bumper will
detect them by bumping into them.</p>        <p>
1. Obstacle detection by the top LiDAR sensor<br/>
2. Obstacles that are placed lower than the LiDAR sensor are detected by the front bumper.<br/>
3. The LiDAR sensor cover acts as a bumper to detect obstacles.
</p>

<li>
<strong>Above the LiDAR sensor</strong><br/>
The cover detects obstacles as it gets pressed.

<li>
<strong>Below the LiDAR sensor</strong><br/>
Bumper detection (* about 58.5mm)(2.3in)<br/>
Climbing a height of 20mm(0.78in)
