New University Project

Postby r0sewhite » Wed Jun 22, 2016 11:54 pm

I just finished the first batch of 10 Rachel, equipped with M4, ESC32 v3, Hacker A20-26M EVO and two Emcotec-Boards.

The Power board comes with
- soft-power-function (onboard pushbutton and connector for external push button)
- power- and CAN-distribution for up to 8 ESCs
- 5V 5A power supply (for powering an Odroid device)
- current metering (up to 50A)
- 2-6S batteries
- safety function for discharged batteries: board doesn't power on if cell voltage is <3.4V

The communication board comes with
- UART with level shifter
- Wifi device, connected to RX port of the M4
- LED controller with 4 LED connectors (probably just to indicate orientation ;) )
- buzzer
- SD cardslot
- all pins from J1 and J2 routed to pin headers, some of them have solder jumpers (i.e. J2-6 to buzzer)
- power supply for 3V3, 5V and battery voltage

All pins are protected against reverse polarity, including the battery connector. Probably Emcotec decided for that because students will work with these copters :)

My personal sample here comes with an additional board carrying the Jeti receiver and an Arduino for converting mavlink to Jeti telemetry. The University will use the onboard CYRF.

Nice!

I'll show a few University people the design and see if there's interest.

Larry: Though the boards match very special requirements of the University of Augsburg, Emcotec is interested in selling them to others. Universities can order complete copters as well as the single boards, if interested.

My next job is building a batch of 10 Saphira (25cm span, 6" prop size) with the same electronic parts and Tiger MN1806 motors. I will post pictures of them soon. Maybe you should tell the Universities about that, too, because I think that the smaller copters will be better for indoor purposes.

The Saphira sounds like a good size for a University copter. I would also give them a 3D printable design for quick detachable prop guards. I found that students like to have a 3D printing project.

Jussi told me that there is some work being done on indoor navigation using a camera. Indoor navigation potential would make the copters more interesting to Universities.
