What is mecanum drive?
Mecanum drive is a method of driving using specially designed wheels that allow the robot to drive in any direction without changing the orientation of the robot. A robot with a conventional drivetrain (4 or six wheels) must turn in the direction it needs to drive.
What is the biggest advantage of a mecanum drive system?
The primary advantage to mecanum drive is the maneuverability it affords, especially because the robot can strafe instead of turn and drive. The rollers on mecanum wheels form a 45 degree angle with the wheel’s axis of rotation, which means that mecanum drivetrains can’t strafe as fast as they can drive forward.
What are wheels in robotics?
Wheeled robots are robots that navigate around the ground using motorized wheels to propel themselves. This design is simpler than using treads or legs and by using wheels they are easier to design, build, and program for movement in flat, not-so-rugged terrain.
How can I control my Mecanum wheel robot?
Controlling the two wheels on one diagonal in the same direction and other two wheels in the opposite direction we get sideways movement as shown in the second figure (move right). You can download my Android app that allows you to control mecanum wheel robot from Google Play: link
What are some example methods on using Mecanum wheels?
Does anyone have some example methods on using Mecanum wheels? The following was translated from Xtensible-isms and accounts for the un-intuitive sign in the gamepad Y values. The left joystick is used to translate the robot, while the right joystick controls the rotation of the robot.
What kind of drive base does Mecanum use?
Mecanum drive is a type of holonomic drive base; meaning that it applies the force of the wheel at a 45° angle to the robot instead of on one of its axes.
What does scaleinput do in Mecanum wheels drive?
This is basically an extension of arcade/POV drive, simply adding the strafe. scaleInput () is part of the util.Range library. One suggestion is to “scale” the inputs to decrease sensitivity near zero (finer control) and faster response toward the limits.
