Comparing Sonar and InfraRed Data
Of course, it was an illusion that I would be able to get straight back to the robot after vacation, there were a few other jobs waiting like the Dyalog’13 Conference Programme (the DyaBot will be making a couple of appearances, of course!). However, it appears I have now made enough flour to be able […]
Return to the Robot
It has been more than a month since my last blog post, and you’d be forgiven for thinking that I’d lost interest in robots. It *is* true that I have been rather distracted by customers, including a trip to the USA. It is also holiday season, and I have been to a music festival. However, […]
Sonar Arrives for the Robot
Following the release of Dyalog APL for the Raspberry Pi came a hectic week with no time to play… But now the next sensor has arrived, so it is time to power the robot back up. In the video below, we practice turning it through 180 degrees using APL.

APL at work in Africa
My dad is originally from the Cape, and I grew up in Botswana, so hopefully I can be forgiven for feeling that it is very cool to find Dyalog APL at the core of a project which aims to increase financial literacy and support the financial stability of small and medium-sized enterprises in South Africa, […]
Elementary Cellular Light-Emitting Automaton
In response to an earlier post on driving an 8-bar LED using the Raspberry Pi, Roger Hui commented that 8 lights should be sufficient to display the output of a 1-d Game of Life. The code snippets displayed in this post are based on some working code that Roger was also kind enough to forward to me. The […]
Dyalog APL v14.0 Tech Preview
And now, as they say, for something completely different. Our robot is running Dyalog APL version 13.2 for the Raspberry Pi, which was released on our major platforms (Windows, Linux, AIX) in January 2013. The next release of Dyalog APL will be version 14.0, which currently has a tentative delivery date of “sometime in the 1st […]
Dyalog APL now available for the Raspberry Pi!
Although the news had not yet appeared on the Dyalog webpage when this was written, the CTO blog has access to exclusive sources and is therefore able to present this scoop: The big day has finally come – Dyalog APL version 13.2 is now available to anyone with a Raspberry Pi, and can be downloaded […]
Fun with APL on the Raspberry Pi (without a Robot)
The official release of Dyalog APL for the Raspberry Pi now looks as if it going to happen on Friday! In preparation for this, we have been working on some examples to demonstrate things you can do on your Pi without a set of wheels attached – like making lights blink! [embedplusvideo height=”356″ width=”584″ standard=”http://www.youtube.com/v/ztLIQgszE1s?fs=1″ […]
Visualising Sensor Data using APL on the Robot
As described in a recent post, our robot now has an Infra-Red distance sensor, which allows us to measure the distance from the front of the robot to the nearest obstacle. With respect to the autonomous navigation code that we wish to write, this will be the cornerstone! In order to evalute the perfomance of […]
C3Pi Opens Eyes at the APL Moot
This weekend, the Dyalog C3Pi reached the final stop on the European spring tour, attending the British APL Association’s Annual General Meeting and “Moot” just north of London, where the robot met the famous mice from Optima. The day before, the C3Pi also travelled to an OSHUG meeting in London on Thursday, where Romilly Cocking was talking about quick2link. Alas, poor C3Pi was […]
