Educational lego nxt robot arm program
The gripper is a complex third class lever linkage. The arm lift is a third class lever too. The small cylinder uses much less air resulting in less pressure loss than the big cylinders. See stroke B and F. How good of a robot operator are you? Find out how quickly and accurately you can pick and place pellets of paper from one circle to another.
First, predict how many pellets you can accurately place within the circle in 30 seconds. Then, test how many pellets you actually place accurately within the circle in 30 seconds. Record your findings on the worksheet. Further investigations Design and make your own grippers that will help you to pick and place different objects of your choice. Students will explore the concepts of: Area Behavior of gases under pressure Friction Scientific investigation Assembling components Control of mechanisms Evaluating Testing before making improvements Using mechanisms - levers.
Mechanism and explanation Systems and system models Structure and Function Stability and change. Science and Engineering Practices Ask questions and Defining Problems Developing and using models Planning and carrying out investigations Using mathematics, Informational and Computer Technology, and computational thinking Analyzing and interpreting data Constructing explanations and designing solutions Engaging in argument from evidence Obtaining, evaluating, and communicating information.

Pump air into the system and use the manometer to detect whether there is an air leak. Try the valve settings and check all moving parts to ensure that they move freely.
Test several times to make sure your results are consistent. The EV3 Home set consists of: An expansion set for the Educational Core Set, which can be bought separately, contains Lego elements. However, the expansion set and the educational set combined do not contain enough components necessary to build most robots of the retail set. This contrasts with the NXT; the educational set combined with the resource set could build any of the retail designs.
The EV3 educational set was released a month earlier than the retail set, on August 1, Robots that can be built with the expansion set are the Tank Bot, the Znap, the Stair Climber, the Elephant and a remote control. Another robot that can be built with a pair of core set and an expansion set is the Spinner Factory. It can boot an alternative operating system from a microSD card, which makes it possible to run ev3dev , a Debian Linux -based operating system.
The EV3 brick cannot be programmed with the standard NXT software, but some third party software supports both systems. On the EV3 AM platform, it is possible with a small hack to double the encoder's resolution.
By enabling edge triggered interrupts on the encoder B line called direction line by Lego , it is possible to have increments per turn instead of This enhancement allows for smoother rotation at low speed and better position control. The modified firmware implementing this modification is called EV3. From Wikipedia, the free encyclopedia. Lego portal Robotics portal. Retrieved 1 October
