The Year 6 students at the school where I work will be investigating
Robotics next term .Since I endeavour to integrate Microworlds
challenges into the curriculum whenever I can, I thought I'd set the
kids the task of using turtles to simulate the movements of a robotic
arm. I'm working on this task myself just to see how it might be done
but I've struck an issue with the clarity of the graphics. I edited a
picture of a robotic arm and separated it into its components - wrist,
arm, shoulder etc. The idea is to have different turtles ' dressed' as
these components. I pasted the original graphic of the arm into several
'slots' in the Shapes/'costume' tab . Then I edited the successive arms
to 'raise' them 10 degrees higher each time . However, when I 'dressed'
a turtle in the arm and made a procedure to 'raise-arm' , as the turtle
puts on each successive arm-costume the clarity/sharpness of the outline
of the arm 'loses definition and the outline looks fuzzy . Does anyone
know of some way of overcoming this problem? I'd very much appreciate
any advice. Thanks in anticipation.
