Eggbot 2- the drawing crumble junkbot.

figure 1 An earlier post https://robotsandphysicalcomputing.blogspot.com/2021/04/junkbots-2-eggbot2.html discussed the start of the development of a two motored Crumble (from Redfern Electronics) based 'junk-bot'; based around controlling vibrating motors ( https://amzn.to/3mtxEy9 ) to move the bot. This post focuses on addressing some of the issues raised in the earlier post. The motors are now glued, via a glue gun, onto the plastic egg (figure 2) and four felt-tip pens are also glued on (see figure 1 above) so there is a firm connection to the egg. Setting the pens in the right positions is the trickest part of the process and you are probably best to experiment with tape / sticky tack before finally gluing them in place. figure 2 figure 3 I like the Crumble for this task because it is designed to control two motors using a simple graphical programming language, without any extra hardware. figure 4 The program shown in figure 4 is trying out a lo...

Junkbots 2 - eggbot2

A new iteration of the junkbots project or more accurately the Crumble-based eggbot sub-project ( https://robotsandphysicalcomputing.blogspot.com/2017/10/crumble-based-junk-eggbot.html ) is underway. Previously it has been built around a single vibrating motor, 'controlled' in the loose sense by a Crumble Controller. ( https://amzn.to/3dNl09e ). The new development is to use smaller vibrating motors but two of them, controlled by the Crumble. This post looks at the early stage of the development and suggests where to go next. Currently, two vibrating motors ( https://amzn.to/3mtxEy9 ) have been attached horizontally to half a plastic egg (figure 1), the kind you can find in dispensing machine with plastic toys, but Kinder Egg ones can also be used. A Crumble is used to control the motors separately (figure 2) by changing the motor's direction. Health warning: It is never going to accurate control but that is part of the charm.

WebVR playtime 2: video, 360 video and objects Using Glitch ( https://glitch.com/ ) as a web development and hosting tool. We are going to create the start of a virtual Gallery, essentially 4 rectangles that images can be posted on, a cylinder that also images can be wrapped around and the floor and the sky.
