Discussions and queries about PicoBorg Reverse

When I run the diddysequence.py script it shows the image below. diddySequence ran on my previous pi, so i don't know if it is the new pi that's causing problems or something else.

Hi there.
Can I control a linear actuator with the PicoBorg Reverse and get control with the Hall Sensor feedback that are already integrated with the linear actuator?
The linear actuator has 6 wires: 2 wires for the motor; 4 wires for the Hall Sensor feedback.
Kind regards,
wizard2010

Currently I am doing a project with the diddyborg robot with the raspberry pi so that it can do obstacle avoidance, and path planning.
Right now it isn't moving , even though the code runs fine where performdrive is called.
Any suggestions?

I need to measure the speed (rpm) of the wheels of my robot and want to use an encoder with the motors. I already have the robot up and running, so I just want to replace one of the motor with the motor+encoder kit and leave the rest of the 5 wheels as it is, with just the motor (no encoder).
Kindly help me in selecting such a motor+encoder kit to be compatible with the rest of the motors (on the 5 wheels). The motors currently on the robot are the DC motors (6V 60 rpm), with metal gearbox.
Thanks

I was wondering whether any reckless roboteer has tried running the diddyborg 6V motors at 9 or 12V? I read that a motor can run a 300-400% over current for perhaps a minute? We're doing the 7m straight line speed test at PiWars which at 6V is taking around 49s - it'd be nice to do it in half that - as long as we didn't fry anything.
Thinking about it now - the motors are supposed to do 60rpm - so is 7 seconds per metre a bit on the slow side? Do you have any timings for the diddyborg when built as per your instructions? I appreciate ours is carrying a little more weight...

I run Diddy headless using VNC and with the WiFi set up as a wireless access point. My sixaxis appears to be working correctly but I am getting strange behaviour. When my Python script is run from Idle (Python 2.7) everything works well. However, if I run the script from a terminal window on the VNC desktop the window is swamped with messages from the controller, such as the following:
"SDL_JoystickGetButton value:0:" and
"SDL_JoystickGetaxis value:0:"

I cant seem to get it to move or run with the PS3 dualshock controler. It worked for about 20 minutes and then I turned it off. I came back two days later and tried to control it again, but it didn't work. There is a red light that flashes every time it doesn't work.
any help would be appreciated

I can not figure out why the Diddyborg is not working. I got the robot to move for about a twenty minute period of time, before I decided it was good, and left it (without changing it). Two days later, I came back, and turned it on. It paired with Bluetooth PS3 Dualshock controller just fine, but when I pressed the buttons on the PS3 controller, it didn't work. On the bottom of the robot, on the (what I believe is the) motor control, a red light blinks on and off, twice every second. When I drove it around two days before, this red light was not blinking.

last night I tried to add an oled panel using i2c, along with the picoborg reverse and the ultraborg. I turned everything on, but after a few minutes (without doing anything, the diddyborg was just sat on the table) I got a rapidly flashing red light on one of the boards and so turned everything off. I took out all of the new cables (I did think it was all wired correctly, but am questioning myself now) and went back to just the battborg + picoborg reverse. Now whenever I turn on the pi I just get into a constant reboot cycle.

Hello everyone
I have a question about the Diddyborg.
Not bought it yet, it will be a Christmas present.
Question is:
What is the size of the gap between the back of the pi camera support and the edge of the HDMI socket on a pi2 when a pi2 is used in the Diddyborg?
I hope that makes sense.
A little more information to help explain.
The manual indicates that the HDMI socket is near impossible to access when in place.
I hope to use a flexible HDMI connector to enable access.
But depends on available space
Thanks
