K9 Photos: Mat Irvine's K9
The above photo is of the control panel of an original K9 owned by Mat Irvine photographed at Smallspace 7, 2018.

K9 at Smallspace 7
K9 became an interloper when we visited Smallspace 7 in Hanslope this weekend, the event was organised by Mat Irvine.
I was very pleased when Mat said that my K9 was one of the better K9's he had seen, and I'm sure he has seen a few. Whilst we were there we drove around the village hall with occasional stops to view the merchandise and for photo ops for K9, lots of people were pleased to see him and asked to take photos and I got so many compliments. Mat even took a photo :)
Although Mat did point out a few deficiencies in my K9 such as the sucker being a little on the small side, and the lack of bumpers, but he was also impressed with my LED panels and said he may borrow the idea in the future.
My interloper K9 did get to pose near the proper K9 (as did I), I also took the opportunity to take lots of detail photos of for future development.

All in all it was a fun day out with lots of interesting merchandise, and my wife even managed to get a shot of K9 with Vila Restal (Blakes 7 - Michael Keating) in the background :)

2nd K9 Continued
After a little work in the garage, I'm begining to see what I need to do to knock this body shell into shape. A little strengthening here and there etc and it should be good to go.
It looks much better with the excess fibreglass cut off.
The second control panel,

Second Head
The Idea is to cut a hole in K9's head to accomodate a speaker, but as I don't want to do major changes to K9 which I cannot easily reverse I thought it best to make a whole new head to work on.
The Gel coat took an exceptionally long time to cure, so I've ordered some fresh catalyst, but in the mean time I removed the part from the mould.
and so it begins |
And did a little tiding up.
Now I'll have to wait for the new catalyst to arrive so progress is halted.
The head ready to come out of the mould.
Next the control panel and side panel. The side panel may
take a little longer as I don’t have a mould for the side panel. The panel I have
on K9-1 is plywood that is impregnated with resin and spray, but I can perhaps
use it as a pattern.

K9 - head upgrades
The visor Arduino Mega is mounted nicely, but the Arduinos for the radar ears and laser is very poor so needs sorting out before I add the extra wiring.

K9 - Control Panel
This weekend I'm changing the button signals to I2C signals. I was disapointed to find that the Raspberry pi could only be a master so will not respond to I2C signal. It will only request data from slaves.
Pre - conversion pic
Progress is slow but getting there.
Arduino Nano One to control the LED's in the switches. Arduino Nano 2 to detect button pushes and send via the I2C bus. Arduino Nano 3 & 4 to control the LED matrix in 2 red displays. Only One LED matrix fitted and half wired.
Power and signals to the control panel through the 9 pin D-type connector.

Red Wedge Down
Whilst reviewing Red Wedge with a view to letting the Young Roboteers a go driving a small combat robot, I realised that one of the wheels was seized. After stripping the gearbox, I found that many of the gears had broken teeth which were jamming the gearbox.
So I need a replacement if Red wedge is to fight again. This is an old motor from an cheep drill I think it was B&Q we got them from. This was before the moder LiPo batter drills.

K9 - Is there anybody home?
ROS on my pi |
With this in mind I'm investigating the Robot Operating System or ROS for short.
It has been painful getting it onto the Raspberry pi, as the instructions are not quite as complete as you would like and my knowledge of the raspberry pi is a little sketchy. Consequently it has taken about a week of the Christmas break to get it installed.
However, it is now on the pi (and backed up) and I've started on the actual ROS tutorials :)
So far I've got as far as driving around a simulated turtle, as above

K9 Diaries - 2017 Mini Maker Faire Derby
K9 had another outing, this time at the Derby Mini Maker Faire, at the Silk Mill Museum on the 28th of October 2017 and look who he snapped on his K9 cam.
Improvements since Whooverville are the tail mechanism and the visor lights, although there were some malfunctions with the visor lights, as some of them wer not working, but this turned out to be just some poor connections.
I usesd an Arduino Mega 2560 for the visor control, mostly because of the large number of I/O's available, and there is a connection to one of the switches on the control panel to change from all on mode to a Knight Rider function.
Below is the mounting of the Arduino Mega 2560, mounted on a plate, which slides into features which are bonded to the inside of the head, then a retaining clip holds it in. I just need to figure out the cable routing.
I've since fixed and added a random function
The tail now also wags at the push of a button on the control panel. This is controlled by an Arduino Nano, with a simple sequence to a servo.
We ordered a Tom Baker cut-out to pose next to K9, who was well received with many people having their photos taken with K9 & Tom and lots of children had fun pushing the buttons.
I'm still working on improvements such as fitting the laser extender mechanism and the Software for the visor lights, which needs changing to an inturrept rather than waiting for the loop to finish before recognising the input.

K9 Diaries - Development
ADC and level shifter |
A simple voltage dividing pair of resistors and a connection to the Raspberry Pi via the I2C bus has been made. The Adafruit library and example program has been added to the Pi and tested, so I just have to wire the inputs to the batteries and adjust the program to monitior the voltage and calibrate the output to reflect the true voltage.
