PicoBorg Reverse and DiddyBorg

Looking for some mounting ideas for these three boards. Right now PicoBorgReverse and BattBorg sit under chassis. Raspberry Pi sits inside chassis along with the battery pack. I am reserving space on top for 4 ultra-sonics and a servo controlled arm via UltraBorg. Not much space left. l am thinking about mounting the UltraBorg between the RPi and the batteries. Not much room there either.

What have others done?

Hi,

I've put together a Web Bluetooth Demo for the 4Borg using a micro:bit instead of a Pi, you can find more info here https://www.thebubbleworks.com/

The demo allows you to control a 4Borg from a browser over Bluetooth LE.

When building the demo I created a reusable mbed library for communicating with the PicoBorg Reverse; which was largely based on the Arduino code found on this forum.

All the demo code and library is open source. (links on the page above)

I am looking to switch from the AA batteries to one battery for the diddyborg. I have a hard time finding how much voltage I need. From the Picoborg reverse specifications, it seem I can have a bettery between 6-25 V, am I right?

I used the Playstation 3 Controller help sheet to install the controller on the DiddyBorg. All went well.

jstest reveals that the controller is connected and that I am get response from the various buttons.

However, when I start ./ps3Diddyjoy.sh, I get the error

./ps3DiddyJoy.sh line 5: sixad: command not found.

The script goes on to load the PicoBoard Reverse and I can use the left joystick to move the DiddyBorg back and forth, but the right joystick does not respond. I did see it respond in jstest.

Can you help?

1. Drive over something conductive, and short circuit the battborg on the underside of the diddyborg.

That's it.

Hi

Can anybody give me an estimate of the time that the stock DiddyBorg will run on batteries when in more-or-less constant motion? I appreciate that many factors affect this.

how many amps does a picoborg reverse need?

I find the method used to stream video in diddyWeb.py to be a bit choppy in responding to movement in the camera's field of view. I have used a method by Dawn Robotics that seemed to stream much more smoothly.

As I am new to video streaming, I am able to implement it, but do not have a real understanding of how it works. Has anyone else been able to get a smoother stream?

I'm looking at aapplication(s) where I will need to compae shape and size with IR signature.

Has anyone experimented with one of these? http://www.amazon.com/Raspberry-Pi-Camera-Filter-Vision/dp/B00G76YEU8/re...

Also wondering if it could be combind with a servo actuated IR filter for better visible light photos as well...

Hi

My DiddyBorg has a custom chassis rather than the official PiBorg one. So the motors are about an inch further apart along their axes, and about a half inch further apart between their spindles.

I've found that it doesn't "tank steer" very well on grippy surfaces like carpet. That is, if I set the opposing wheels to rotate in different directions, I want the whole platform to rotate about its axis (more or less). It does tank steer OK on wood and tile floors. But on carpet it tends to judder and rotate unevenly.
