Robots and Physical Computing

Up to this point the junk bot building has largely being about building a moving (or drawing) 'bot' moved by vibration - limited control, but fun.  A  Nuffield funded bursary studen t, Hayden Tetley,  has being working within staff from the University of Northampton on whether LEGO 8547: Mindstorms NXT 2.0: Robot or Raspberry Pi based solutions can be incorporated with the bot to add some control of the movement (still by vibration). Idea One  Is to add a LEGO NXT brick, to move a junkbot similar.The motor and broken propeller combination in the earlier junkbots is replaced with the NXT brick and LEGO motor. A good potential feature is it a self-contained unit with power and control together, as well as being potentially fairly simple to set-up. This is the focus of this post.  Here are some videos showing idea one in action using LEGO motors, brick and the software that comes with the LEGO 8547: Mindstorms NXT 2.0: Robot : For more information on how t...

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 ...

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; This post contin ues  with small robot idea a bit more, looking at some of the other robots I have been fortunate to be able to play with. The opinions are from a personal point of view of playing with them, but comments are very welcome. Kbots The kilobots ( http://www.k-team.com/mobile-robotics-products/kilobot )were designed to be relatively low-cost devices specifically designed for work on swarm/collective intelligence experiments. Developed at Harvard University as a scalable system to program groups of robots (now into the thousands) ( http://www.eecs.harvard.edu/ssr/projects/progSA/kilobot.html ). Individually these are quite simple units, they move by vibration. The real advantage, in my opinion, of the system though i...

Sameer Kumar Shrestha, Northampton The report presents the dissertation on title  Prototype of Sentry Robots for Advanced Security  which includes the use of LEGO robots showing interaction between each other with the help of wireless communication medium in Bluetooth. The purpose of the work is to build a communication between multiple LEGO robots using the wireless technology. For this task, the NXT version of LEGO Mindstorms has been selected. It is because there is need of complex communication which is possible through wireless medium such as Bluetooth and also a suitable processing device for the proposed task which is present in the LEGO Mindstorms NXT. The report has also focused on the background information about the NXT system and its great flexibility with LeJOS NXJ as the programming platform. The outcome is the implementation of developed work with the use LEGO Mindstorms NXT and the LeJOS NXJ as programming platform. The task was approached with one LEGO...
