What is the diameter of a VEX wheel?

Size: Diameter: 4.000″ (101.6mm). Width: 1.125″ (28.6mm). 4″ Omni-Directional Wheel Weight: 0.232 lbs (105 grams).

How is the choice of VEX IQ wheel related to the rate of the robot’s traveling?

A larger the ground clearance will make it easier for the robot to travel over obstacles. The greater the traction of a wheel, the harder the robot can push or pull, and the easier the robot can travel over obstacles. However, if a wheel has a high degree of traction it is harder for the robot to turn.

What is the circumference of a Vex Omni wheel?

The standard VEX IQ wheels are 200 mm circumference, which also works out quite well to being almost exactly 5x VEX pitch / 2.5 inch diameter.

How does wheel size affect your robot?

Choose smaller sized wheel for flat terrain, larger wheel for more “off-road” (or large obstacles) Proportional to the size of the robot (choosing a wheel proportional to the size of the robot will usually mean the motor you will need is also proportional, and the robot has a better chance of moving at a decent speed)

How much does robot weigh if its mass is 0.125 slug?

How much does robot weigh if its mass is 0.125 slug? 4 lbs.

What is gear ratio in vex?

VEX Plastic Gears, Sprockets, and Pulleys may also be used for power transfer. In this case, the input and output Gears/Sprockets/Pulleys will be the same size so there is no change to the torque or the rotational speed. This is often called an 1:1 ratio.

What is Vex V5?

VEX V5 represents our fifth generation of education robotics systems developed with 20 years of experience using robotics to teach STEM principles. VEX allows students to hone critical computational thinking skills needed to succeed in both the 21st century’s workforce and in everyday life.

What is VEX IQ?

VEX IQ is a programmable, snap-together, robotics system. Watch code come alive on a physical robot and learn key STEM skills that easily transition into the real world.

Do Omni wheels create friction?

Omni wheels DO have “friction in all directions”, and they obviously roll, but the effective tangential friction is vastly lower in the direction of the axis of rotation due to the rollers around the circumference of the wheel.

Where are omni wheels used?

They are often used in intelligent robot research for small autonomous robots. In projects such as VEX Robotics, Robocup and FIRST Robotics, many robots use these wheels to have the ability to move in all directions.

What is VEXcode VR?

VEXcode VR lets you code a virtual robot using a block based coding environment powered by Scratch Blocks. VEXcode VR is based on VEXcode, the same programming environment used for VEX 123, GO, IQ and V5 robots. We all know that robots make Computer Science (CS) come to life with real world applications.

How does the size of wheels affect speed?

A larger diameter means that the wheel will be heavier and consequently speed will be slightly compromised during acceleration (depending also on the torque of the car); Bigger wheels will also increase the maximum load of the car.

How does wheel size affect torque?

This torque value can be calculated using the radius of the wheel and the tangential force produced by the wheel. So, increasing your wheel size will decrease the driving force from your wheels which will culminate in a decrease in acceleration of said wheels.

How many wheels should a robot have?

Robots can have any number of wheels, but three wheels are sufficient for static and dynamic balance. Additional wheels can add to balance; however, additional mechanisms will be required to keep all the wheels in the ground, when the terrain is not flat.
