No need for all attachments to be powered by motors and to include gears. It's sometimes possible to use a simple robot attachment to collect objects. Such attachments we call passive and this one is an example for the Box Robot Chassis.
Build with LEGO Mindstorms EV3
Разполагахме с няколко минути преди да започнем да строим друг робот и ни хрумна идеята за този. Ако искате да построите Box робот, но нямате достатъчно части, това е една добра конструкция, с която може да се упражнявате. При нея има рамка и три мотора, като може да добавите и приставки.
Experiment with changing the orientation and direction of gear wheels. Here are part of the tasks that you should complete before moving forward with the course.
We should multiply the error by a certain number and then add it to the steering of the LEGO Mindstorms Steering block. In this way, by changing the coefficient we change how much/fast should the proportional part influence the steering of the robot.
We got the speed of rotations of the motor in Radians per second. Let's calculate the value for the speed of the whole system. We calculate that the wheels are rotating with 375 radians per second. Which is impressive and quite fast for this system. From this speed, knowing the inertia mass we can calculate how much energy is the system accumulating.
A program, that makes the Turtle follow a designated course and get back to it, even if it's been manually rotated. It also hides in its shell when it sees anything close to it.
Careful: Gyro Sensor port in this program is port 3. Check your cables when you run this program.
NOTE: The program contains my blocks, that will appear broken if you use version before 1.3.0 of the EV3 Mindstorms Software
This is the attachment of Team "Nightbeast", with which they do:
M11–Escape Velocity and M13–Observatory
The Observatory result depends on the model. Sometimes the pointer is in the orange area otherwise in the white area.
Това са инструкции за моделите на мисии Swing и Traffic Jam. И двете мисии са в торбичка 9 от комплекта за FIRST LEGO Лига 2019-2020 City Shaper.
