Robots and Physical Computing

In the previous two posts, mentioned the low-cost small devices are opening up new opportunities for robotics ( http://robotsandphysicalcomputing.blogspot.co.uk/2015/10/it-is-good-time-part-one-introduction.html ) and the rise of social robots in the home ( http://robotsandphysicalcomputing.blogspot.co.uk/2015/10/it-is-good-time-2-social-robots.html ) was considered. In this post and the next, 'small' robots (my phrase), relatively low cost robots, are considered. A few examples are discussed. Picobot One of the most interesting small robots on the market is the PicoBot from 4Tronix ( http://4tronix.co.uk/blog/?p=708 ).  These are small, relatively low-cost robots with a good range of basic sensors based around Arduino. A nice feature is they are quick to put together (5-10 minutes each for the two above).  The size, time to build and the radio modules make them an interesting option for playing with swarm robotics - if only I had the money. Don't let the swarm ro...
