Apr.10 Building

The lab in May needs Lego constructions to be programmed using IEC 61499.
http://www.nxtprograms.com/ projects are a good starting place to look for models to program with IEC 61499.  A modified NXT Robot Arm will be used in the May lab. Today built, modified, and tried 2 more nxtprogram projects. The Peg Sorter will also work for a quick lab exercise.  Turning "Forklist"  needs modification and may not be ready for May lab.


NXT Forklist that turns like NXT Robot Arm
So today modified the NXT Forklist to turn in circle like the NXT Robot Arm and go up and down. Only still need to go in and out and putting on a "car" may be the easiest solution.


NXT Peg Sorter 
This construction uses a light sensor and 2 motors. 
Modified so the peg pusher can be returned to it beginning "open" position.
Possible problem, if the motor stops, so white pegs are not free to fall through.
Need to test. Possibly change construction slightly.
