Educational lego nxt robot arm program
Investigate how to make the most energy efficient sequence for a Robot Arm. Robotic arms are used for jobs that involve picking up, moving and placing objects. Usually they do jobs which are difficult or repetitive, and need to be done quick and efficiently. To achieve maximum efficiency, the picking and placing sequence needs to be decided beforehand. Build the Robot Arm and investigate how to make the most energy efficient sequence of strokes.
Then turn the arm to its resting position: Hint The easiest way educational lego nxt robot arm program empty the air tank is to disconnect the tube going from the air tank to the valve.
What is the most energy efficient sequence? Find out which sequence is the most energy efficient for picking and placing objects. First, predict which sequence of strokes is the most energy efficient at picking and placing a pellet of paper. Your sequence has to start in the resting position, use all six movements at least once and then return to the resting position. Record your predictions on the worksheet. Then, test your sequence of strokes and note the loss of pressure after each stroke.
Record your findings on the worksheet and graph paper. It takes eight strokes to complete the work cycle and back to the resting position. If the object is dropped without lowering the arm it can be done in six strokes. 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 educational lego nxt robot arm program.
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 Educational lego nxt robot arm program components Control of mechanisms Evaluating Testing before making improvements Using mechanisms - levers.

Try the educational lego nxt robot arm program settings and check all moving parts to ensure that they move freely. Test several times to make sure your results are consistent. Have the students reflect on their investigations by asking questions such as: Repeat the test three times to see if your speed and accuracy improve.
Hint To help overcome the loss educational lego nxt robot arm program pressure, you could build a compressor. Area cylinder grip levers manometer mass pressure pump valve.

The "EV" designation refers to the "evolution" of the Mindstorms product line. It was officially announced on January 4, and was released in stores on September 1, The education edition was released on August 1, It comes with the plans to build 5 different robots: Lego has also released instructions online to build 12 additional projects: However it can also be programmed on the actual robot and saved.
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 educational lego nxt robot arm program 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. Educational lego nxt robot arm program 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 ev3deva 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 Legoit 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 educational lego nxt robot arm program However not all software features are supported by the NXT intelligent Brick.
