Here's next week's video, early for Patrons. This one goes out publicly next Tuesday 31st.

I thought I'd try a fairly simple Arduino tutorial type of video. It's one line of code (well actually two) which make animatronics and robotics move more smoothly. I deliberately used the cheapest most basic servos I could find, and it all runs on an Arduino Uno.

I'm open to suggestions for other simple ideas and demos - as long as it can be presented in an accessible way.

Servo Smoothing - PREVIEW VERSION

There are lots of great animatronic and robotics props and projects out there, and it's easy to make r/c servos and other actuators move using the Arduino servo library. This means that the servos stops and start very suddenly, moving as fast as they can between positions. In this video I'm going to show you two lines of very simple code to make things smoother.

Love the build. Thanks for the tutorial. Did you consider repurposing Ultron's head for this. 😄

Al Pieroway

I love watching the bigger builds because you make it look so easy. :). But this is easy enough that I can actually see myself building it as a real first time intro to all this.

XRobots

I didn't actually - I just thought I'd make something with really obvious motions that's looks nice ;-)

XRobots

Thanks - I've just added the Github link to the video description with the CAD and code

Excellent James. I'd still like to see a breakdown of your universal remote both transmitter and receiver, but not sure if that fits your criteria of a simple tutorial?

Loved this! I’ve been trying to do something similar but the delays were getting in the way. I didn’t know there were alternatives.

XRobots

There are a couple of ways of doing it, I think this is the easiest though.

James - I just watched your touch screen remote vid but the joysticks in this video look better (you mentioned in the remote video that the joysticks had a lot of play in the centre. Have you, by any chance, got a link for the ones you used in this project? Thanks

XRobots

They are the same, but I'm removing the deadspot in the code. They are about £10 on eBay from China.

You could install an NRF24L01 into the ROS remote so it could communicate with other robots as well as ROS robots.
