Started Sep 20, 2016 0 Replies

Does anyone know of a commercial IMU specifically designed for use in UGVs with electric motors?  I'm looking for a product that can take into account the transient magnetic fields and that doesn't…Continue

Here's an unusual question: Is it possible to disable the radio?I've got a device that's got a radio soldered on to it so it's not possible to unplug it.  But I'm not using the radio so I'd like to…Continue

"And I have to say that I'm not a fan of joysticks that I can't pinch.  Thumbs, IMHO, are not a precision instrument."

"I'm surprised that a company like Futaba hasn't come up with a radio that uses wifi, an iOS or Android tablet as a user-interface, and has a video feed.  Hell, they sell a friggin' $3000 radio that does nothing more than their…"

Nikola Rabchevsky commented on luke cooke's blog post Why the need For an 2,4ghz RC uplink?
"It's not just about the frequency.  Sure, 5.8 GHz is less crowded but 2.4 GHz inherently gives you better range and signal propagation through foliage.  IMHO, the elegance of the Solo design is that there is one RF link handling…"

Nikola Rabchevsky commented on Emlid's blog post Introducing Edge - Advanced drone controller with HDMI video input and 5.8GHz data link
"So, this looks like there is a separate video link and control link.  Am I correct? If so, this is why I still love my 3DR Solo.  One link to rule them all, one link to find them, one link to bring them all, and in the darkness bind them."

Nikola Rabchevsky commented on sander's blog post DeltaQuad VTOL completes 100KM autonomous mission carrying a 1KG payload
"I'm curious as to why this needs a $700 Lipo pack when a similar pack can be had for $145.  Granted the C rating is less but does this thing really need to pull more than 200 amps to run?"
