Although it has a short cameo, the Netduino 3 is endorsed (and used) for a project with my son.  We made a robot that I could control from a hotel room while I am away on business trips.  This robot allows me to keep our learning projects going while I'm away.  

As a parent, it still allows me to be involved in parenting as well as you will see at the end in a comedic way.

Below is the link to the video.  The video is designed to be shown to his school mates (10 and under).

• Selectable Modes: Stick Control, Autonomous Movement
• Sound: triggers on distance in either mode
• 4 Threads running at all times: Determining/playing a sound based on distance from an object or time, determining distance from objects in front, setting preferred speed and direction based on the current mode and distance from an object, sending motor drivers pulses based on the preferred speed and direction

• Turning speed scaled down so one doesn't have to be an expert to drive him.
• Forward movement interlocks if an object is ~2 feet in front

• Object in zone 3, R2 goes forward and turns in the same direction as his last turn. If he doesn't find a clear path in a few seconds, he stops and yells.
• Object in zone 2, R2 stops and spins in a circle in a random direction. If he doesn't find a clear path in a few seconds, he stops and yells.
• Objects in zone 1, R2 stops and yells. He then backs up and turns 90 degrees.
• If object is in zone 14 and the pitch knob is turned up, he'll do a dance to the 8-bit sounding Cantina song.
• All other zones, R2 drives forward...the further from an object, the faster he goes.

This is a very early showcase of the code I wrote for the Netduino to control an R2D2.  To build the R2 this far, it took over 2 years of research, wood, plastic, and aluminum work.  I'm now back in my wheelhouse with programming and am loving the Netduino Plus 2.

http://www.youtube.c...h?v=vLJb6dg859Y

In the last few days, I cobbled some code that seems to use the Netduino Plus 2 PWM pins to reliably read data from an RC receiver.

While searching the web for code, I found countless posts that the Netduino Plus 2 either can't do it or is not reliable to do it.  But, I'm living proof that it does it.

Is this just an "Apple vs. PC"-like phenomenon on the web, or should I not trust the Netduino Plus 2 to reliably read RC data - particularly in the application of motor control?

So far, I'm only using it to trigger audio on an MP3Trigger.  However, my next target is to receive drive and direction from an RC controller, process it against sensors with the Netduino Plus 2, and then send the appropriate PWM to the motor driver.

Thanks in advance for any advice,
