machine can effectively detect obstacles in front upon a slight physical impact.
8. Q: Why is there a circular orange rotating component protruding from the top? Is it normal
that the top cover can be pushed? Is it normal that the top cover is loose?
A: The protruding part on the top is the LDS (laser distance sensor), which is a core component
of the machine. It rotates constantly at 300 RPM to obtain topographic data of the environment
in which the machine is placed. The laser distance sensor is fitted with an external protective
cover. On the bottom of the LDS top cover is the LDS cover bumper sensor, which is capable
of detecting any foreign matter that may get stuck in the laser head and enabling the machine
to automatically move backwards to prevent the machine from getting stuck.
9. Q: What's the hole in the front of the machine?
A: This is the machine's recharge sensor, which allows to machine to align with the dock charger
for recharging.
10. Q: What are things on the two rear sides of the machine?

11. Q: What are the two metal tabs on the bottom of the machine?
A: Two metal tabs on the bottom of the machine are the positive and negative terminals of the
charging contact. They come into contact with the charging tab of the dock charger to enable
the machine to charge properly.
12. Q: What's the black area on the white dock charger?
A: This is the signal transmission area for the dock charger where the IR recharge signal is
transmitted to guide the machine to correctly align with the recharge port for charging.
13. Q: What is the metal strip that can be pressed on the bottom of the dock charger?
A: This is the charging tab of the dock charger. It comes into contact with the charging contact
on the bottom of the machine body to enable the robot to charge and it is flexible to ensure
