Making Controlled Turns with the DyaBot
This blog originally started when I took delivery of the DyaBot, a Raspberry Pi and Arduino based variant of the C3Pi running Dyalog v13.2. The architecture of the ‘bot and instructions for building your own inexpensive robot can all be found in blog entries from April to July of last year. The downside of only using inexpensive components is […]
Dancing with the Bots
Last week the ‘bots were busy preparing for the J Language Conference in Toronto, where they made their first public appearance together. Upon returning to Bramley they continued training and we are proud to present the first recording of their new dance: [embedplusvideo height=”400″ width=”584″ editlink=”http://bit.ly/1u6Knob” standard=”http://www.youtube.com/v/oO50UqFBsCw?fs=1&vq=hd720″ vars=”ytid=oO50UqFBsCw&width=584&height=400&start=&stop=&rs=w&hd=1&autoplay=0&react=1&chapters=¬es=” id=”ep3993″ /] The ‘bots are both running […]
Aligning Diff Output
‘Bots are off limits this week so here is a story from this year’s Iverson College – a fantastic week spent in the company of a wonderful mixture of array and functional language gurus and newbies, all learning from each other. One evening, Dhru Patel presented a problem that he was working on which involved […]
The Blog is Back!
It is now 3 weeks since we shipped Dyalog version 14.0 and released the new Dyalog web site, so it’s probably time to stop celebrating and get back to work. The ‘bot batteries have been recharged and the ‘bots are learning to work as a team using v14.0 futures and isolates. That’s all I can […]
APL-Controlled Robot Performs Death-Defying Stunts Using PiCam
Regular readers will remember my whining about the poor precision of both infra-red and ultrasonic sensors. But today, the Raspberry Pi / Dyalog APL – controlled “DyaBot” was observed driving on a dinner table – where the slightest navigational error could mean a 3-foot plunge and certain death! How can this be? [embedplusvideo height=”400″ width=”584″ editlink=”http://bit.ly/19azC9S” […]
PiServer at Thor8.dk
I’ve been wanting to run a Web Server from my home for many years. In fact, I have been paying for the domain Thor8.dk (my street address is Thorsvænget 8), and a fixed IP address for 5 years now – without getting it implemented. But today, with a little help from Jason Rivers who helped […]
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. [embedplusvideo height=”356″ width=”584″ standard=”http://www.youtube.com/v/W6IIcNK0g0U?fs=1″ vars=”ytid=W6IIcNK0g0U&width=584&height=356&start=&stop=&rs=w&hd=0&autoplay=0&react=1&chapters=¬es=” id=”ep8492″ […]
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, […]
