So going by what they aimed for in building the laser: No. The nominal power and wave length of all of these appliances is less harming to the eye than going outside on a sunny day and forgetting your sun glasses.

The issue here I guess are malfunctions or rather cheap products with bad calibration. For total safety you'd have to get someone to measure input and output of the laser.

I'd love to reassure you about something like low input power, but at the end of the day with cheap products you don't know. If a higher powered laser was cheaper at the time of production, the extra milliwatts would probably be negligible compared to overall power consumption of the robot.

So the lidar is unlikely to immediately cause eye damage at a glimpse, but if your kid likes to chase the robot and thus might look into it for longer periods of time, maybe look into options of checking the laser's actual input power.

Keep in mind that LIDAR is moving lasers too, which are allowed to be higher power but should have an interlock that turns the laser off when it stops moving.

I'll leave the extrapolation on how that could go wrong to you.

Hmm my kid does like to chase the robot.

It seems rather difficult to measure the laser input power though. Apart from trying to reverse engineer the robot?

I guess I'll just make sure that it's not turned on if my kid is awake at home.
