Hello,
I assembled the Adventure Robot and have it working with the RGB Animation Display and the Ultrasonic Sensor. All seems to be working for the most part but I have a few questions and concerns:
The camera has a green LED showing on the lower right inside case of the camera. Don't remember seeing this in any of the videos. Is this normal?
In the camera settings, the only resolution available was 320X240. Does this have to do with my laptop or am I missing something?
I tried going into the media settings for the camera to select different codecs and frame rates etc., and selected change and saved the settings but no changes were noticed with the video.
Sometimes the robot would make random movements with the servos without me actually controlling them. Sometimes the servos would make small step motions and sometimes longer duration motions and in random directions. I had speech recognition enabled so I put it on pause and things seemed to work o.k. Could the speech recognition being enabled all the time cause these random movements and if not what other issues could cause these random movements. Battery temp and voltage are o.k. as I charged the batteries before using. I have a strong good WIFI Connection.
In the mobile app for the Adventure bot all works o.k. but when I select stop the robot instead moves left continuously. Has anybody seen this before. Seems like maybe a good opportunity for me to learn from this and try and correct it by modifying the script?
I noticed when operating on the rug (not shag) that the tail behind the Adventure Robot would hang up on the rug and prevent proper movement. Was thinking that some kind of EZ-Bit that is in the form of a little caster wheel would solve this issue but I am not experienced with CAD Programs and don't have a 3D Printer. Maybe this is something that EZ-Robots can work on as a future EZ-Bit as it could be used in a lot of future creations that use a three wheel type of a platform and would work better on rugs. On wood floors and linoleum it isn't an issue. Another thing I thought of doing is putting wide rubber bands around the wheels for a bit better traction
I will be doing a STEM demonstration of my Heathkit Hero Robots and I will also be showing off the EZ-Robot Products that I have. The hardware and software is way awesome. I have been able to get speech recognition working pretty much flawlessly and all the other hardware is working good with just a few issues with the intermittent random servo movements and some camera setup issues that I am sure can be resolved.
Thanks for an awesome product at a great price. I now have the bug !
Do this in the mobile interface by editing the existing Adventure Bot app and resave it to the cloud as your own...
Thanks much DJ ! From what I have read it appears that C++ and other languages can be used to program the robots using appropriate SDK'S. Would this be a correct assumption? Thanks again ! Rick B.
The software tab will tell you everything you will need to know about creating plugins or use the sdk.
I would recommend staying in ARC and using EZ-Script.
Hello,
I read the tutorial for the ADC Ports and have Some questions:
Is the VDC pin an input or output? If so what is the output voltage if it is in fact an output voltage? If it is an input what is its purpose. The analog input voltage appears to go to the signal input pin.
With regards to the VDC pin, what exactly does 5 volt tolerant actually mean?
Am I correct in assuming that the analog input voltage is applied between the ground pin and the signal pin and must be between 0-3 volts?
What is the reference voltage for the internal ADC
Is VDC used as an output for voltage divider to ground. Say if you had a potentiometer you could connect one end of the potentiometer to VDC, the other end to GND pin and the wiper connected to SIGNAL pin of ADC.
Having a schematic diagram of how the three pins connect internally to the ADC would be helpful.
If the input voltage is 0 to 3.3 volts how are you using a 5 volt sensor input. Seems there would be some circuitry required to scale the higher input voltage down to the ADC input range of 0-3.3 volts.
Thanks again for your help ! Rick B.

it's an error:
The VDC pin is a 3.3v regulated OUTPUT voltage pin The Signal pin is an INPUT pin (5v tolerant)
ADC reference voltage is 3.3v ADC resolution is 12 bits
if you feed 3.3v (ADC VDC) to the Signal input pin (adc0)
5V tolerant means if you feed more than 3.3v you don't burn the EZB, but will have erratic readings.
if you want to read more than 3.3v you will need a voltage divider.
As an example to step down an interval 5v-0v to 3.3v-0v you can use:
if you get noisy readings you can add a 100nF capacitor in parallel with the 3.3k resistor.
A voltage divider can be used to step down voltages but should not be used to supply voltage to a circuit.
Thanks much ptp ! That helps alot !......Rick B.
