Re: Cloud robotics demo code

This is quite strange. i had a similar problem with my rangefinder but i managed to get values after I initialised it in arduino. Here is what my arduino script looks like (i am using the PiControl base sketch) */ #include "Hardware.h" void setup(){ // ************ THE SETUP ITEMS BELOW SH...

Re: Cloud robotics demo code

https://photos.app.goo.gl/hx9gXN5FmgjjyN6h2 This is the final design of the sensor GUI. It seems to be working fine. The screenshot is with the rover sitting on my desk. Unless I am missing something, this should cover every environment sensor on the rover. Does anyone know if there are additional ...

Re: Cloud robotics demo code

here is a little teaser of the graphs from the surface and range sensor along with motor speeds. I will extend this to include all the sensors on board.

Cloud robotics demo code (now with actual code and links to BBC and FT)

Starting a thread now for some code I am planning to upload next week for a demo organised by King's College London and Ericsson to demonstrate cloud robotics over a prototype 5G network deployment in London. With that said, what is the prefered method for sharing code with the community? The code p...

Thanks so much. I thought the USB port was only there to program the arduino. I haven't tried plugging it yet. I guess I should have tried that first :)

how to charge the battery?

can i charge that battery straight from the rover or will I need a separate charger for it? I see there is a DC barrel connector but I am not sure what voltage to apply there and if I can charge the battery from it.
Also, is there a protection circuit for the battery?
