Classic Projects (Chapter 14)


The most classic project to do is the detection of obstacles in a room. When doing this you need a couple of sensors. The ones that are used to do this is the Ultrasonic Sensor, Touch sensor and the light sensor. When doing this it is important to decrease the speed of the robot so it has a chance to register the object. Indirect obstacle detection is when for example a touch sensor is pushed until it is released so it rater detects the release then the push an "In Direct (not Direct)" It also talks about a steering follower. It is a steering assembly with a light sensor that keeps trying to follow a line and by doing that steering the robot after that line. It mentions some methods how to increase the speed. They are changing gears, Changing wheels and Decreasing weight. It is important o decrease gear slack because it can make the robot malfunction by the gears hacking and being damaged.

Some nice techniques outlined in this summary that is definitely applicable when trying to maximize a robot's performance.

Yeah, I agree with him. Good job. But I have a question. At the bottom of the touch sensor block, there are three choices such as pushed, released, etc. What do they mean? Can you tell me?
