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.

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 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!

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 […]

Driving my Pi

Back from the APL meeting in Hamburg, where my C3Pi made it’s first appearance on German soil (and a few days meeting with APL users in Milan). I’ve extended the control program which was used to make last week’s figure 8 video to give me some “hand controls”. I do appreciate that it is inadvisable for humans to […]

APL – Coming to a Robot Near You

APL on the C3Pi One of the biggest joys of being the CTO of Dyalog is that you get to write code to help evaluate prototypes of proposed language features, or new tools and tutorials that we are planning to make available. This past week has been one of the most exciting for a very […]
