We set up a bunch of Martys with a set of tuned bells, and got them to play festive songs!
Here is Jingle Bells:

Here's Noel, Noel:
Noel, Noel - but played by Marty the Robot!

Hi all,
I have just put a new Raspberry Pi image into the folder at https://public.robotical.io/index.html?prefix=raspberry-pi-img/, robotical-pi-2018-12-04a.img.zip.
Main updates are:

We're testing a new feature that lets you control Marty directly through the Marty Setup network, rather than using an external WiFi network, it's called Direct Connect.
From the app you can now remote control and calibrate Marty without needing to connect to a WiFi network, and if you load up this version of the Scratch interface, you can then switch to your Marty's Setup wifi network and p…

Hi all, it's about time that we gave some more information on how to get a camera enabled Marty working. We also need to explain more about what ROS is, and why its so awesome. This is the first part of a short series of posts I'll be making, hopefully each weekend.
I'll try and keep things as simple as I can, but to get the most from this you should have some knowledge of Python, and be comfortable typing stuff into a terminal. I've tried to explain the gist of what's happening in each step, but there a…

Hi all,
I've been putting together a little rudimentary remote control for Marty. It's not quite ready for release yet, but it would be good to get a few people trying it out and checking for errors
You can get to it at http://docs.robotical.io/rc/rc.html.
It gives you a few buttons to control Marty, as well as a D-Pad and an analog joystick for moving Marty around
It uses the same Marty …

We're working on making the Marty scanning tools more robust, but while we're doing that there are other ways to get your Marty connected
If you've done the WiFi setup, and Marty is connected to your WiFi (so there's no "Marty Setup" network any more), then here's a video showing how you can find Marty's IP address directly, and use that in calibration tool or Scratch.
Finding Marty's IP
Quick overviewIn case you don't like watching videos - he…

Hi folks,
I've just made a couple of tweaks to Marty's scratch interfaces, both the Basic one and the Extended one
Two minor updates:
The get ready block should now also un-pause movement Adding a Marty by IP should now be much quickerAnd one bigger update - the sidestep block! …

As a fun and fairly simple Scratch project, I've been programming Marty to shake hands!
This demonstrates few concepts - we have to move joints, show expressions - but to do it properly we also need to know whether somebody has grabbed Marty's hand - and for that we need to read the sensors!
It'll look a bit like this:

Getting started - handshake movementsThere will be two main bits to this …

Hello,
The logic is 5v tolerant, so it's fine to put 5v on the inputs there. The microswitch is just works very simply by switching 5v on…
