I get the feeling this is a very technological forum, and I know my question will seem simplistic. My apologies, but I have had great difficulty in trying to find out what components of Mindstorm would help me complete the following project. I cannot find any Mindstorm forums other than yours. If there is one more suitable to my question please let me know.
I presently do not own any Mindstorm sets. I want to make something similar to this crossbow project: http://robotfilia.blogspot.com/
However, I do not want to shoot a projectile. I just want the 'robot' to very slowly raise and lower a string - up and down - that is all.
I have a young son, and he has a toy acrobat bear that rides and balances on a string running across his room. We can make the bear glide back and forth by lowering and raising the string,
but I would like to have a 'robot motor' move the string up and down a track like the one in the crossbow. I would attach the track to one wall, attach the string, and then program the 'robot' to raise and lower that string. The balancing bear is very light - perhaps half a kilo or less in weight.
Which Mindstorm set or which Mindstorm motors would I need to complete such a project ? Which one do you think was used in the crossbow project?
Thank you very much. Heel hartelijk bedankt ( I've been to Rotterdam a couple of times. I always enjoy being in the Nederlands.)
