We set up a bunch of Martys with a set of tuned bells, and got them to play festive songs!

Direct Connect Beta Test Feedback

Posted 21:28:34, 06th September 2018   |   № 121

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…

Advanced Marty #1 - Raspberry Pi Camera and Ball Following

Posted 09:38:43, 23rd October 2017   |   № 65

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…

Web Remote Control - in beta

Posted 14:44:33, 17th September 2017   |   № 55

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 …

What to do if Calibration or Scratch can't find your Marty

Posted 17:41:38, 02nd September 2017   |   № 44

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 overview

In case you don't like watching videos - he…

Scratch updates - New block: Sidestep!

Posted 17:01:50, 01st September 2017   |   № 41

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 quicker

And one bigger update - the sidestep block! …

Marty Scratch Fun - Shaking Hands!

Posted 17:58:05, 13th August 2017   |   № 18

Marty Scratch - Shaking Hands

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:

handshake video

Getting started - handshake movements

There will be two main bits to this …
