VR ESC 2.0 Tech Preview

Hello everyone,
after some years of absence from the portfolio of the esc VR, I present the new design.
We made choices very conservative to have 27 and 50 amp ESC from 4s to 6s ... we are doing tests and validations necessary because this is a very delicate component.
Here are the first photos and video of the first test.
The firmware supported are the Simonk and BHely, given the complexity of the topic we did not want to reinvent the wheel but to make a quality product that can be certified and has the ability to be installed on a dedicated distribution board.

Attached are photos and here is the video

Now that Tony Cairoli can fully enjoy about the newly conquered eighth world title in Motocross, Red Bull can reveal some details that have contributed to the success. Here's one: about a year ago, the team of the hugely popular energy drink has involved our Team to create a telemetry system (baptized then Connected Rider and proved an excellent device, almost to Formula One) for use during workouts Tony , to track its performance and uncover the secrets of his guide so unique riding his KTM 350 SX-F.

CRESTED BUTTE, Colo. -- We still don't have hoverboards or flying cars, but in the glorious future we live in today, we do have flying robots that can bring us beer. Unfortunately for those in the United States, the Federal Aviation Administration won't yet allow drones for commercial use. That means that while it's OK to fly beers around to your buddies in your spare time, no paid or promotional delivery services are allowed just yet.

But that hasn't stopped brew titan Anheuser-Busch InBev from looking into how drones might be able to help keep the party going in the near future. The company brought some experimental prototypes to Whatever, USA -- a fictional town that Bud Light created in Colorado last weekend for the purposes of throwing a party for 1,000 contest winners and creating all kind of new promotional content -- where I got an in-person demonstration.

I spoke with Federico Treu and Roberto Navoni of an outfit based in California and Italy called XTrace about the Bud Light delivery system that they worked up for "Whatever." Essentially, it's a custom-built quadcopter that's a slave to a beacon that also functions as a very simple remote control. Push one button, and the drone comes to you; a different button and it returns to where it started. Push a third button and the drone will follow you at a safe distance.

The small, lightweight drone can only carry one bottle of beer at a time, but it's still an important proof of concept for lazy beer drinkers everywhere. The drone can easily function as a push-button bartender or a beer-caddy, following you down the street with refreshment just hovering a few feet away, just in case you need a drink (the fourth and last button on the remote tells the drone to land where it is).

"When we started this project, the idea was that, it's really difficult to fly drones," Treu told me outside the Crested Butte "Whatever" Visitors' Center. "But drones nowadays are smart enough to follow you, so even people that have never tried can fly a drone -- just hold the beacon, press the button and go."

For drone nerds, there are also some interesting things going on behind the scenes of what seems like a simple remote-controlled drone setup. For the prototypes in use at "Whatever," Navoni is in charge of safety. He walks around wearing Google Glass running a custom-made Glass app that provides him with a view of what the drone is seeing, as well as all the relevant statuses for the drones current operation.

In other words, while it may seem almost like a simple toy, Navoni is able to monitor everything that's happening with the drone through Glass and take over control of the drone if need be.

Treu says the next challenge for their drones is to automate obstacle avoidance. He says the drone in use at "Whatever" only has a carrying capacity of about 1 pound, but other form factors could easily handle bigger loads.

The drones came to "Whatever, USA" as part of a partnership through the "beer garage," a sort of skunkworks lab run out of San Francisco that looks at use digital tools and other innovations to promote brands like Bud Light.

Check out a delivery in action in the video below. The entire sequence was done by pressing only two buttons on the beacon.

After the latest firmware release, vrb supports RtOS for operation.

A neat feature is the advanced and quasi-unlimited logging capabilities. The logs will be written after each flight session and they are stored on SdCard.

on Vrb 5.0 the microsd adapter is on board, but for owners (like me) of the previous hw revision, we need to work creatively.

the standard SD-CARDs is accesible via SPI bus, and the mandatory connections are : MISO(master-in-slave-out) / MOSI (master-out-slave-in) / SCK (clock) / SS (signal-select) / GND and VCC+.

all of them is available on JP27  connector (the white one near the INPUT rails). This one, has 8 pin connections, we need (as stated before) only six of them.

We can figure out which ones by looking at image below.

pin-1 is the one which is more close to MCU (the big chip on the center of the board); pin-8 is the one near the input rails.


I could buy a specific adapter for sd card, but I decided to be creative and I invented this system, which at the moment seems to work very well.


Basically I used a simple adapter sdcard-> microsd and I soldered directly to the exposed pad on the back as shown.


all the connections are straight point-to-point. watch out for "exp_EN" which connects to SS on sd card adapter. i've ordered pre-crimped cables and the female terminal directly at VirtualRobotix.

You can check if everything works correctly by connecting the VRB with sd-card inserted in Mission planner and connect with Terminal. Once connected, enter in "TEST" and then in "SHELL".

Check for a folder called "APM" into fs/microsd path.

No more configuration is necessary.

Now the system will log all the flight data on different files on sd, and you can retrive them by simply unplugging the card from the copter and reading it with a computer.


NOT all microSD is +5v tolerant on vcc. so i've tested a solution using a 78l33 linear regulator soldered directly on pads.


the "VCC_5V" connection goes in the In pin of the 78l33 (pin3), gnd on sdcard pad 3 and the output of the 78l33 goes to pad 4.

The mod works flawlessly.

check datasheet of 78l33 for pinout numbering.
