Kaluma-9 (K9) update
UPDATE: okay, as previously mentioned I spent a little bit of time ( on a Saturday evening ) looking to use a Raspberry Pi PICO W and a Robo Pico board, along with a very old Dr.Who K9 robot toy to create a functioning "modern day" object avoidance detection robot. No rocket science going on here, execpt me being me, I wanted to use JavaScript and NOT Python to control everything. Why JavaScript? Well, when coding for Arduino you are using C. The cleanest and most sensible coding language to use ( ignore all that modern day OOP rubbish that people attempted to shove on/around it - that just ruined it, sometimes Software Architect are NOT right & if you accept that, you then chose what is best for the job, rather than forcing everything to fit what you know, bit of a life lesson there, me's thinks ) for the task at hand whilst running on constrained embedded devices. Well, I'm not using an Arduino atm, however, I might, so to make the "switch" easier...
