EMME "Technology is not complicated"

Let´s go! create your own Emme, you 3D print the parts and prepare your own configuration.

The new waterproof connectors seems grate, I think I´m going to test it on the sea in the next weeks. 

Every Emme can "connect" with another, four wheels configuration it´s one of the options.

The actual configurations use an electronic component to convert the volts of the batery to 3.3V to power the electronics. The next design of Emme dont need this component because with a new custom pcb the electronics can take the power directlly to only one cell of the batteries, but for now is neccesary a new cover to evacuate the hot temperature from the 3.3 volt converter,

The stl of the new cover is ready to download at the files section.

The box encapsule the electronics and you have acces for the batery connectors and for motor connector, with that is easier test the model before close the "wheel pack".

There is a new Firmware to increase the Speed at Github. Actually the hackaday prize prototypes have the slow speed firmware, now I upload to github a new version of the Controller Prism firmware to have fast speed on the motors. This new firmware can be upload to the Controller Prism via USB.

Slow speed:

Modular design "check", on road pads "check", off-road pads "check", water accessories "check", underwater accessories "check".

Now I´m designing the new hardware for ESP32 from Espressif and doing the maker manuals with the electronics diagrams ;)

3D Printing this shelter for design and use your own hardware with sensors and all your stuff inner the second or inner the third triangle of the Emme´s body, the A123D file, and the STL file are ready to download at the files section.

You can modify the firmware of the control prism and the wheel firmware to have other functions to broadcast the messages between the control prism and your new accessory.

Enjoy ;)

Reduce the number of the total parts and looking for new solutions for the wheel suspension, the gray pads are interchangeable.

White PLA and some parts for the different sizes, thanks to my printer I can study the best size option for the first working Prototype.
