Free Computing Resource: Junkbots and Scratch 1

The Junkbots project has been running for a number of years as an initiative to bring sustainability, computing and engineering together by building bots out of junk details of the project can be found at. https://junkbots.blogspot.com/. Junkbot is an extension of the Research into teaching problem-solving going on at the University of Northampton please feel to visit https://computingnorthampton.blogspot.com/2019/01/problem-solving-research-outputs-and.html for more details.

One of the criticism of the robot programming part of the Junkbots project is not everyone necessarily gets a go at the programming. To address this a new feature has been added to the project, using Scratch to play with the ideas. This is the first of a set exercises to play with these ideas. The cleaning robot shown is loosely based on the LEGO Mindstorms RCX.

The commands all in the My Blocks section

Exercise 1: Moving the Robot Cleaner around.:

Now go to https://scratch.mit.edu/projects/384342734 and rewrite the code so the robot moves in a square.

Exercise 2

Now go to https://scratch.mit.edu/projects/384347284 run the code (or try it below) and see what it does. Now alter the code in the RCX sprite to get the robot to push the purple drinks can across the line.

Please share and post comments on either the comments blog or on the scratch projects. It would be great to see how you do with this.

Problem-solving or computational Thinking

Confession time, this has been a research interest for me, along with a number of colleagues, since around 2005. It started with undergraduate students - investigating teaching and developing problem solving skills as a first step in developing programming skills through the use of LEGO-based robots and graphics based programming for undergraduate students. The main vehicle then for developing the problem-solving skills was the LEGO RCX Mindstorms robotics kits and series of gradually more challenging robot-based tasks. Lawhead et al (2003) stated that robots “…provide entry level programming students with a physical model to visually demonstrate concepts” and “the most important benefit of using robots in teaching introductory courses is the focus provided on learning language independent, persistent truths about programming and programming techniques. Robots readily illustrate the idea of computation as interaction”. Synergies can be made with our wo...

Problem Solving Open educational Resource

Another new Open Education Resource (OER) has been made available by the School of Science and Technology, University of Northampton. Problem-Solving Author: Dr Scott Turner http://find.jorum.ac.uk/resources/19001 Details These mini lectures are intended for undergraduate computing students, for providing simple steps in problem solving before the students learn a programming language. Problem-Solving and Programming is a common first year undergraduate module on the BSc Computing Programme at the University of Northampton. This material was taken from the problem solving part of the module and provides an introduction to five topics in problem-solving. The resource can be found at: http://find.jorum.ac.uk/resources/19001 After one week on JORUM 93 downloads and 12 views of the OER.
