DIMM 'the OOD' Cardboard Robot

CBiS Education generously sent me two of their new range of robotics development kits - BinaryBots  (https://www.binarybots.co.uk/makers.aspx), these are a range of cardboard based kits (so far a robot and a UFO) with electronic components for example LEDs; sensors and buzzers,  depending on the kits. What makes the kits interesting though is they are designed to be controlled by either by a BBC Micro:bit or a CodeBug.In an earlier post,  I played with the UFO one (http://robotsandphysicalcomputing.blogspot.co.uk/2016/08/ufo-detects-light.html), now I have had a chance to play the DIMM the robot.

With the wires hanging out of the mouth and its humanoid shape it reminds we a bit of the OOD from Doctor Who (https://en.wikipedia.org/wiki/Ood) but a lot more unthreatening.




How to build it video from @cbiseducation is shown below.




So I built a Light detection system with the light sensor that came with the kit and added a microbit. The idea was
- to play one sound when the light level is low as well display an 'L' on the Microbit;
- to play another sound when the light level is higher and display an 'H' on the Microbit.

The code used is shown below. It is built around the forever loop, the light sensor is connected to Pin 1 and the speaker on Pin 0 (ground and Vcc connected as appropriate see the robot below). when the sensor value is greater than 175 then the low light level is detected otherwise the higher light is detected.


The video below shows this enjoyable kit in action - the sound level is a bit low in the video.

Micro:bit, Servo control with Micropython or blocks

You can control servos (small ones) from a Micro:Bit directly. Following a link from the David Whale (Twitter ) , thank you, took me to a Kitronik blog post, https://www.kitronik.co.uk/blog/using-bbc-microbit-control-servo/, which has the answer.

The code uses Microsoft Blocks taken from the post, runs the servos 180 degrees and back again, when button A is pressed. It does exactly what it should. I am also using the Tower Pro SG90 servo.
Can it be replicated in Micropython? This is a new mini project, there seems to be little out there yet on how do this but the best so far is this video by PHILG2864:



The closest I have is the following, it is essentially there.
from microbit import *
pin0.set_analog_period(20)
while True:
    pin0.write_analog(180)
    sleep(1000)
    pin0.write_analog(1)
    sleep(1000)

Setting the time period to 20ms  pin0.set_analog_period(20)seems by experiment (and used in the video above) to be best value so far. The reason for pin0.write_analog(1)  set to 1 i…

LittleBits Star Wars Droid and Swift Playgrounds

On the 1st September 2017, during 'Force Friday', LittleBits launched their new kit Star Wars Droid Inventor Kit an R2D2 shaped robot, though you are encouraged to customise it to form your own designs. It comes a number of tutorials, that take you through building a moving head, a proximity sensor to move away from you, and many others.


So confession time, I am not the target audience for this kit, but I have enjoyed playing with it. The tutorials take you through building and dismantling the kit, doing a range of different activities and in most cases controlling it remotely from an iPad. You can even record your voice and have it played back from the Droid, in my opinion, the wide of sounds is one of the things that lift this from being just a nice kit -  I will get onto the other one soon. Though good fun, I was left with a question can it be programmed?

This was my first time using a LittleBits kit I didn't know what the options were available for programming it, a quic…

my robot BETT2017

I will start with a confession, I only had about 2 1/2 hours at BETT 2017 due to external time pressures so to say I didn't yet a chance for a good (or even a bad) look around is an understatement; so I am not reviewing the show just a few notes on what I did manage to see.


STEAM Village
First and mostly, it was great to talk to so many people, only few I had met face to face previously, about robots, micro:bits, Raspberry Pis and coding. Most of this happen in the relatively small (compared to the event space) STEAM village and nearby stalls. It was great to see the strong presence of both Raspberry Pi and Micro:Bit Foundation, along the variety of different activities and example usage of both, with Code Club (I know it is part of Raspberry Pi Foundation) there was well. This was all alongside some other companies

Four of these stuck in my mind.
