To this end, they decided to use LEGO bricks due to the system and diversity of pieces, and the Logo language due to the groups familiarity with the software and its ease of use. : 3 Similar to the "floor turtle" robots used to demonstrate Logo commands in the real world, a construction system that ran Logo commands would also demonstrate them in the real world, but allowing the child to construct their own creations benefitted the learning experience by putting them in control In considering which construction system to partner with, they wanted a "low floor high ceiling" approach, something that was easy to pick up but very powerful. : 55–56 As the types of programs created were limited by the shape of the Turtle, the idea came up to make a construction kit that could use Logo commands to animate a creation of the learner's own design. : 14 Papert had previously created the Logo programming language as a tool to "support the development of new ways of thinking and learning", : xiv and employed "Turtle" robots to physically act out the programs in the real world. In 1985 Seymour Papert, Mitchel Resnick and Stephen Ocko created a company called Microworlds with the intent of developing a construction kit that could be animated by computers for educational purposes. 2 Robotics Discovery Set and Droid/Darkside Developer Kit.

1.3 Logo Brick 1st Generation, "Grey Brick" (1986).None of the teams used #2 of the accepted answer. None of the teams switch automagically to the rotation sensors when the gyro is known to be drifting. None of the teams displayed a warning as a sound, a blinking light, or a message on the LCD panel before the robot left the home base.

None of the teams did the work of recording the drifting episodes to a file. One team used the gyro to go straight, sort of a proportional line follower with a gyro sensor instead of light sensor. Some pivoted, some spinned, and some accepted any motion.

Clearly, they had worried a lot and then figured out how to use it. In front of the judges, they used the gyro. They had gone to the trouble because of the bad reputation of the Gyro sensor.

It allowed them to retreat from using the gyro sensor if they needed to. One team had a set of MyBlocks that turned based on either the rotation sensors or the gyro sensor. The first to "still" the robot the second to ensure the zeroing of the gyro angle had been taken. That team also added a 1 second wait before and after the double reset. One of those teams said they had followed the advice of some site on the internet. This reset being the reset of the Gyro angle to 0. No twitching meant it was ok.Ī different set of two teams added a double reset of the gyro.

Another ran the robot through a routine that cause the robot to twitch if it was drifting. One waited 10 seconds to see if the drift was still less than 2 degrees. Two teams had tests to avoid leaving home base with a "drifting" gyro. They varied in whether they paused before, during, and after each step. I hadn't heard that before and have no idea if it has any basis in fact.Īlmost all of the teams used the "Simple Gyro Fix" mentioned in the original question. One team, not one of the 5, had given up on using the gyro in the belief that it could not be place close to the rechargeable battery pack because the gyro sensor would get too hot. Each team had some part of the answer, but none had everything. That said, none of their solutions were complete. It is unfair to those teams, since their research does represent a significant advantage over other teams. The Gyro is a tricky sensor to use, but at yesterday's FLL competition in Elk River, at least 5 teams had worked out the issues to their satisfaction.
