Maybe referring to linear maps would make it clearer to people new to the field? Linear function is quite an overloaded term, and i think "map" works quite nicely with the concept of moving one space onto another.
About 2 years ago I sat through a presentation by somebody in another part of my company where they had built up a robotic system to perform some tasks. The audience was all super interested and attentive and it certainly seemed like they all were believing this person had done something amazing. 1/3 of the presentation talking about how the person had built up a python library to do coordinate transforms. When he finished his presentation, I raised my hand and asked " Um, WHY didn't you use ROS? It would have done ALL of this FOR YOU. It would have taken you < 10 hours to do everything you spent 6 months building". Everyone in the room gasped and looked at me. The presenter meekly said "Um, I didn't know about ROS". I smacked my forehead.
Yeah it's crazy! My company is still using a custom transform system I knocked up years ago and every time I need to work on it I think we should just switch it over to ROS and be done with it. We'll get there one day...
As a roboticist who works with ROS(2), I must say these videos are really something. At the moment maybe the best step by step guide available on the internet!! :) Among infinite number of questions that exist in Robotics and in ROS programming a big one for a newbie is: what are the dominant characterstics for a laptop/pc to be able to work laglessly with ROS(2)?
Thanks! I guess that's one of those "how long is a piece of string" questions. In my day job I work on systems with multiple lidars with large scans (over 1M data points/sec on each one) and this takes quite a bit of processing! On the other hand, the stuff I've shown in my other videos doesn't take much at all. I'd generally recommend a recent i5, 16GB RAM as a starting point but there really are so many options!
I'm working with the Falcon haptic right now but i have trouble with writing code for publisher and subcriber to publish the position of haptic for the mobile robot ( using raspberry 3) and subcribe the data from RPLidar. How should i do now ? I'm not good at coding :
