Online Tools & Tutorials

Building a robot is not always easy, especially if you don't have any previous experience or people to help you or guide you. LMR is in a perfect place to help others online and the more tools and tutorials a user has access to the better. We've put together a few over the years and if you know of any or even want to make your own, add them in the comments, and we'll add them to the main post. We'll also take a look on LMR to see if this type of comprehensive "Tools & Tutorials" post has been done before and integrate them all into a mega post.

Object tracking servo jitters... in only one direction?

I've come across a problem during the fine-tuning of my object tracker. When the "neck" servo is steadily decending positions (turning to the left) the movement is smooth, even with decrements > 1. It acts completely different when turning right. There is a distict pause between each SERVOPOS and I noticed it takes longer to process a debug cycle as well. The head shakes, rattles and rolls, the values used to adjust turning speed based on object distance are insufficient, and it just looks terrible.

Object tracking with a SRF05 sensor

hey guys, 

i was interested in building an object tracker using my srf05 sensor. i got an answer from CtC which i did'nt understand clearly, so any suggestions on how i can do it?

picaxe basic, how to program to do two things at once

I successfuly built the LMR robot and it works.  Now I want to add some flashing LEDS to flash while the robot is moving.  I wrote a program to make them flash and that works,  I just can't figure how to incorporate that. seems I need to do two things at once???
