How to build junkbots: Drinks can, unbalanced motor

The junkbots project has now being running for 18 months in Northamptonshire, UK. But how have the junkbots being built? A video produced by one of the particpants can be found here , showing some of the examples. Several ways have been investigated by the participants in the next few blogs some of these will be talked about. Let's start with the main approach, simplest way and probably the quickest:- A drink can and an unbalanced motor - shaking its way around. Take a 330ml drinks can and put it on its side. Fix an electric motor over one end of the can, packing tape is good for this (but not very environmentally friendly). Attach something to the motor's spindle that unbalances the motor, the goal is to get it vibrating. Broken propellers, cogs with Blu-tak, cogs with modelling clay have all being tried. The problem with this, is turn the motor on and the junkbots rolls over onto it side and goes around in circles. A couple of fixes students have tried, adding outrigg...

Junkbots gets younger.

The Junkbots project, has up to this point, being focussed on students between the ages 11-14 years old. Recent developments in the project have lead to some of the material being delivered to younger children. During September 2010  the robot programming side of the project was both developed further and delivered by the two new facilitators Kumuditha Kariyawasam and Aleksandra Dziubek.(see picture), two final year Computing students from the School of science and Technology, University of Northampton, UK. Their material was developed to make this side of project more accessible to a younger group, but also to appeal to girls a little more. An example of the material can be found by clicking on the link here . Along side this in November, the part of project building robots out of 'junk' was used with a group of Beaver Scouts (5-8 years old) in a Northamptonshire village. One of the Beaver's said he wants to build a "junkbot factory". The success and the le...

Student Feedback from Brooke Weston

Thank you to the students and staff at Brooke Weston School, Corby, UK for working with us on this project. Here are some of the comments made by the students. Several of the students identified some interesting features about building robots out of 'junk': "We had the [f]reedom to show the teachers what skills we have" (Student B) "interesting overall" (Student H) "...but frustrating because modifications were frequent" (Student J) "The activity was very fun and creative. We experience lots of difficulties to overcome." (Student K) "it was nice have time off timetable once in a while" (Student N) "I found that building the junk bots has made me some new friends..." (Student T) "...as we[ we]re able to put any ideas forward to put ideas forward to create our own creation" (Student V) The programming of the robots caused a differences in opinion which seemed to come down to two main factors, that th...

Brooke Weston Event

Students at Brooke Weston School, Corby have been working with the University of Northampton's School of Science and Technology on the junkbots project. Scott Turner and Terry Tudor on the 16th and 17th February 2010 went to the school to run the sessions. Starting with a talk and activities on waste management, including how much waste the UK produced, and in terms of numbers of slices of toast what is the cost of energy of leaving a monitor on overnight.   The task was to produce robots out of rubbish that could carry other rubbish into a containment area. The change made to the sessions was that students brought there own 'junk' to the sessions. S ome innovative and creative designs were produced involving 'legs', wheels (including turning cans into wheels and wheels from old toys).    Some of the designs pushed rubbish into the area, but one of the designs carried the rubbish into the area and some designs used magnets to pick up small steel parts (nuts a...
