Hug Avoider 2 - #4tronix #Eggbit




starting hug avoider 2



In an earlier post this year ( 4tronix Eggbit - cute and wearable - hug avoider) I played with 4Tronix's Eggbit (in fact I bought three of them https://shop.4tronix.co.uk/collections/bbc-micro-bit/products/eggbit-three-pack-special  :-) recently). In that one I used a microbit V1.

In this post, I am using a microbit V2 and replicating the idea but with adding a sound; when people get too close as a bit of fun and surprise for relatives at christmas. 

The code written using Makecode for Microbit (https://makecode.microbit.org/) and the extension for it 4Tronix's developed (see https://4tronix.co.uk/blog/?p=2485 for more details)  is shown below:


makecode for microbit for the hug 2 avoider

Essentially the device goes on; puts a message on the LED display "Hug Avoider 2" and then puts a rainbow on the neopixel syle LEDs and a smile on the small 'mouth' - if the ultrasonic sensor doesn't pick up anyone in front.


No one getting ready to hug


If the ultrasonic sensor picks up anyone in front; LEDS change to red, a sped-up version of one of the standard tunes in Makercode is played and the mouth changes to a surprised look.

detecting someone is too close





Good fun, didn't stop anyone and my son made one with the LEDs lighting up as the person got closer.


What I want to look at is the possibility of programming it with Python - something for the new year.

Robot Software

In the previous blog posts for this 'series' "It is a good time...."  Post 1  looked at the hardware unpinning some of this positive rise in robots; Post 2  looked at social robots; Post 3  looked at a collection of small robots; Post 4 looked at further examples of small robots Robots, such as the forthcoming Buddy and JIBO, will be based some established open sourceand other technologies. Jibo will be based around various technologies including Electron and JavaScript (for more details see:  http://blog.jibo.com/2015/07/29/jibo-making-development-readily-accessible-to-all-developers/ ). Buddy is expected to be developed around tools for Unity3d, Arduino and OpenCV, and support Python, C++, C#, Java and JavaScript (for more details see http://www.roboticstrends.com/article/customize_your_buddy_companion_robot_with_this_software_development_kit ).  This post contin ues with some of the software being used with the smaller robots.  A number ...

Speech Recognition in Scratch 3 - turning Hello into Bonjour!

The Raspberry Pi Foundation recently released a programming activity Alien Language , with support Dale from Machine Learning for Kids , that is a brilliant use of Scratch 3 - Speech Recognition to control a sprite in an alien language. Do the activity, and it is very much worth doing, and it will make sense! I  would also recommend going to the  machinelearningforkids.co.uk   site anyway it is full of exciting things to do (for example loads of activities  https://machinelearningforkids.co.uk/#!/worksheets  ) . Scratch 3 has lots of extensions that are accessible through the Extension button in the Scratch 3 editor (see below) which add new fun new blocks to play with. The critical thing for this post is  Machine Learning for Kids  have created a Scratch 3 template with their own extensions for Scratch 3 within it  https://machinelearningforkids.co.uk/scratch3/ . One of which is a Speech to Text extension (see below). You must use this one ...

Escape the Maze with a VR robot - Vex VR

You don't need to buy a robot to get programming a robot, now there are a range of free and relatively simple to start with robot simulators to play with. Three examples are listed below: - Make code for Lego EV3  https://robotsandphysicalcomputing.blogspot.com/2020/05/programming-robots-virtually-3-lego-ev3.html   - i Robot simulator  https://robotsandphysicalcomputing.blogspot.com/2020/04/programming-robots-virtually-2-irobot.html - Vex robotics Vexcode VR   https://robotsandphysicalcomputing.blogspot.com/2020/04/programming-robots-virtually-1-vexcode.html   It is the last one of these ( https://www.vexrobotics.com/vexcode-vr ) that is the focus of this post and return to hit, after an earlier discussion in  https://robotsandphysicalcomputing.blogspot.com/2020/04/programming-robots-virtually-1-vexcode.html   .  Two of the nice things about the package, apart from being free, are it uses a Scratch-like programming language and it provides a ...
