Wednesday 12 July, 2006 at 9:58Current Challenge: Beginner's Challenge/Maze
Problem: We had difficulty with problem no. 6. The containers were slightly confusing at first, because of the odd way that you must program the numbers to change and how it appears on the RPX.
Solution: We followed the program design that Mr. Jones posted, and were able to make it work with a few minor changes.
Problem: On the maze, we had a difficult time getting it to bounce it's way through. It kept just bouncing one time.
Solution:We are still working on it, but we think that our program was wired wrong.
Problem: We were not sure how to get music, but then we saw how to.
Solution:After we knew how, we had some fun making up music for it to play.

Wednesday 12 July, 2006 at 2:29Current Challenge: Beginner's Challenge/Maze
Problem: The problem is that the robot wouldn't stop on the line. It stopped in the black area.
Solution: We solved the problem by adding a modifier to the block diagram. Also we switched to motor's power to 1, so it wouldn't go past the line. The robot was going so fast, by the time it reached memory, it was past the line. Eventually the motor would stop on the thin, black line.

Wednesday 12 July, 2006 at 2:47Current Challenge: Robot going back and forth.
Problem: Our problem was that the touch sensors were missplaced and the robot when it hits the wall, it just keeps going forward.
Solution: We discovered a way to make a ram touch, and we switched ththe touch sensors and with the ram touch, when it hits the wall, it will go backwards.

Thursday 13 July, 2006 at 9:40Current Challenge: Maze
Problem: We had no clue on how to make the Maze program! We tried many programs, but none of them seemed to work at all! We tried random direction, task splitting, and random motor, yet they kept causing errors.
Solution: Mr.Jones showed us how to use this icon that randomly chooses to go eithor left or right. We still have not worked all of the bugs out, but it almost works.
Problem: We had trouble finding wheels that fit the robot. The wheels were too small, or too big. We changed the form of our robot , and we thought that it might work, but it still didn't.
Solution:We took off some Legos from the bottom, and made the strength of the motor 2.
Problem: Our robot will not move once it hits a wall. It goes forward, but then stops. We think that the program contradicts itself, causing the motors to stop.
Solution:We did not have enough time to come up with a solution. We printed some pictures of our program to review over the weekend.

Thursday 13 July, 2006 at 9:57Current Challenge: intermidiate challange
Problem: the program for part 4 of the I.C. is very wrong because when it reachs a line it just keeps going backwards and doing weird turns
Solution: the teacher twisted our desine so it would have better comunication, but it still refuses to work the right way.
Problem: the light sensor didn't work to sense the lines and turn correctly.
Solution:i needed to use a light sensor forck instead of just a light sensor symbol like i was using before

Thursday 13 July, 2006 at 9:59Current Challenge: intermediate challange 4
Problem: we have to make our bot hit a wallthen reverse then it has to randomly decide wether to go foward or to turn slightly at an angle and when it turn keep its count on a container and after four times make a noise then stop

Monday 17 July, 2006 at 10:03Current Challenge: intermidiate challange
Problem: problem 3 of the I.C. had a weird problem with the random fork. 20 times in a row it would do the back and turn but would never continue going foward.
Solution: im sort of confused as to how i got the solution. we basically just mixed the wires in the programand and reprogramed it alittle and add a new loop to repeat the program enough times until it finally became random
Problem: not much a problem as a new solution. the teacher told me that if the loops were mixed with the forks that it would have many bugs and problems.
Solution:i went against what he said and the program work mulitple times with a few adjustments to the speed and engines.
ralbrad
Monday 17 July, 2006 at 10:02Current Challenge: Maze
Problem: We had a problem with the robot making it around the corners. It would go half way through the maze and then get stuck.
Solution: We made the robot shorter and thinner to. It worked some times, but others it still got a little stuck but it would get farther than it orginally did.
Problem: We tried to have the robot follow the dark line instead of hit the walls but it wasn't working right. The wheels would go in the wrong direction and it would avoid the line instead.
Solution:We fixed the program by swiching the direction the wheels were going, changed the light sensitivity, and slowed down the motors. It dosen't work right just yet but it's pretty close.

leevan
Monday 17 July, 2006 at 2:07Current Challenge: maze crawler
Problem: We are tyring to get the maze crawler to go through the maze. A huge problem that we arehaving, is that the robot is notreading the line. There is a red and black line, so it is hard to read the difference between the lines.
Solution: We haven't found a solution yet to these big problems with the light sensor. WE will probobly have to bounce are way through the maze.
Problem: we had troble bouncing throgh the maze.
Solution:we shorted the front and back of the robot to get farther.

Problem: Our touch sensor was being pressed down too much by the apparatus used to extend its range.
Solution: We took off some of the apparatus, hooking up a smaller Lego to it.
Problem: We uploaded a program from our robot, and it was drastically altered. We could not understand the new program.
Solution:We re-did the program from scratch. It worked perfectly!
Problem: Our touch sensor was falling off every time it hit something.
Solution:We lowered the motor level and made the item hooked several ways instead of just one way.

Problem: Our robocop does not turn on the black line and instead continues straight.
Solution:We are going to try a light sensor fork set to a specific light level to give it its task. If the light is greater than 30 it turns for a quarter second back on to the line. If it is less than 30 it continues straight on the black line.

Solution: Our solution was, we sped up the fly- trap and slowed down the time it takes to close the flytrap

Problem: The problem was that I couldn't get the program to connect all 4 commands.
Solution: The attempted solution was that we asked the person who made the program, but they didn't even know. After that we figled with the program, but got nothing. Hope to make it work in the end of today, or tomorrow.

Problem: Our touch sensor or our wheel will fall off after spending too much time in the maze. When we lower the power setting, the robot doesn't work at all.
Solution: We built the robot stronger (again) so the program we made for it worked after a few tries without breaking.
Problem: Someone... sends viruses to us while we are trying to test our program!
Solution:Return the favor.:)

Monday 24 July, 2006 at 9:36Current Challenge: Intermediate challenge
Problem: We had no clue how to make the claws for number 5. Either it was too complex to build, too simple to work, or too hard to program.
Solution: We ended up using an idea that Mr. Jones showed us. It left one claw still, and attached the claw to the gear (which faced up).
Problem: The gear went too fast the first time we tried. We changed the power level to one, but that was too slow.
Solution: We set the power level for motor B to 2. It then worked, almost finishing the task.
Problem: Our claws were not wide enough for the can that we were trying to grasp to hang on to it.
Solution:We moved our motor farther to the side, allowing a wider space to grasp onto the can.

Problem: We tried to make the robot go faster. Using some containers and motors to make the speed 25 on the computor.
Solution: The teacher told us that even if the program says 25 it can only go to 5. He also told us that faster is not the answer. He showed us that if we put a small gear on the motor then add a big gear on to the small gear that gives it more power.

Monday 24 July, 2006 at 10:01Current Challenge: venus fly trap
Problem: The robot breaks or drops or jams or does nothing when an object is dropped.
Solution: We have to make the touch sensor abble to sense the object each time possible by moving it closer to the center. We must find a way to strengthen almost all parts of it without it breaking. Also, our catching area should be better enclosed in order to avoid it jamming the motor.

Problem: the problem was that the robot was working until i tried to put something on to make it better and it fell apart
