Omni wheels Omni Wheel, also known as Poly Wheel, it is similar to Mecanum wheel. Omni wheel are very unique because they are able to move in many directions and it has small discs around the wheel will roll with full force, but will also slide laterally with great ease. Hey Chief Delphi Forum, We are the Charging Champions, a six-member rookie FTC team from SoCal. Being quite unfamiliar with the TETRIX kit components, we were contemplating on whether to buy eight 4-inch omni wheels with two wheels at each corner or four 4-inch mecanum wheels. 12/09/2015 · Quick tutorial on how to use and program mecanum wheels, allowing side-to-side movement in addition to normal tank drive motion. For more information on. Vectoring robots with Omni or Mecanum wheels How Vectoring Movement is Possible. Vectoring movement is achieved through a sum of forces generated by each wheel. In Figure 1 below, you will notice that for the robot to move to the right motor A will need to move in the negative direction and motors B and C would move in the positive direction. While it does have more traction than omni and a less even power distribution, mecanum is more prone to slipping or being pushed than tank drive. There are several available mecanum wheels that FTC teams can use. Andymark Mecanum Wheels- These are made so they have the tetrix hub hole pattern drilled onto the wheel.

Here is a diagram of the direction of the force of each wheel when moving forward: To drive forward/backward, you just power all the wheels forward/backward. To turn right, you power the right wheels backward and the left wheels forward, just like normal wheels.
Mecanum wheels allow savvy robot designers to create drivetrains capable of moving in any direction using a standard chassis shape. Simply power each wheel with a different motor and change the directions the wheels spin to get your robot to move in different directions! Mecanum wheel assembly hardware is separate from sprocket mounting hardware. Mecanum wheels provide a different force on the ground than the regular wheels. The way they are shaped causes them to make a force vector that looks like this: These are the forces that the wheels create when they are moving forward. The opposite force is made when they are reversed. The left side wheels create a force that opposes the right side. FTC 12547 Student. 4 minutes ago. How much weight can Omni wheels support.

For this reason some teams have found that using a mixture of regular wheels and Omni wheels works better than the latter or former on their own.
– Spec Ops. features typically raise center of gravity so plan to be low early in design for chassis. • Choose Wheels types and location carefully – Traction will always come in to play at some point. Keep it in mind when choosing Omni wheels. • Think about motor location for ease of. The advantages of the Mecanum wheel: omnidirectional movement, cool shape. Then there are the disadvantages: expensive, difficult to process 90% are metal, heavy, slow, long life relative to the traditional rubber wheel, each motor has to drive each wheel separately and then the advantage of the omnidirectional wheel: Large robots can. Omnidirectional Drive Systems Kinematics and Control Presented by: Andy Baker President, AndyMark, Inc., FRC 45 Ian Mackenzie Master’s Student, Univ. of Waterloo, FRC 1114. Who?. • Killough Drive, using omni-wheels • Mecanum Drive • Ball Drive 2008 FIRST Robotics Conference. Swerve drive, team 1114, 2004. Swerve drive, team 47, 2000. The wheels probably aren't the problem, but at an angle they don't have the traction to push the stone down the chassis is designed so that they have poor traction. If you've built a tank drive chassis with omni wheels, simply replace your front two with normal wheels and it should work much better while still having significant mobility.
Basically, the diagonals must fight each other to strafe. This means that they can’t move forward or backward, so the wheels move side to side. So diagonal pairs are positive and negative respectively to strafe. You must test this if you don’t know the force vectors of the wheels to figure out which configuration is left/right.

wheel and Omni wheel. The strength of theses wheels are the enhanced maneuverability of the mobile robot that needs extreme maneuverability in congested environment. Moreover, building mecanum wheels and Omni wheel mobile robot provides a stringent test bed for new concepts and approaches in both mechanical design for mecanum.
