Dagu Gear Motor Pain

Haven't touched the dusted Mindstorm NXT at corner for long time I decide to combine it with lots of parts salvage from friends for 4 leg walker. The leg idea … Read more

Ultrasonic Ping Module. Range.

Hi All,

I tried to find information about the real distance measurement of the ultrasonic module HC-RS04 but without success.

In the description it is written that range is 0-4.5m (0-5m in another source) but in reality I can only measure the distance up to 2.5m

Does anybody know anything about it?

Is it okay for those crapy sensors from e-bay?

Thank you guys in advance!

Cheers!
