Exploring Science and Maths with Mini 4WDs
Welcome to Mini4Science
Mini4Science is an educational channel where we bring science and mathematics to life with Mini 4WDs.
About our Mini 4WDs
Our Mini 4WD development prototypes are based on Tamiya Mini 4WDs with MA chassis. We added a computer, sensors, data storage and software which enable us to do scientific experiments with our Mini 4WDs. Find out more here.

Science 101
Gear Ratios
Let’s learn about gear ratios and explore the different gear sets of the Tamiya Mini 4WD PRO.
Torque and Acceleration
What is motor torque? And how does it translate to acceleration? Let’s explore.
Distance, time and speed
What is speed? How does it relate to distance and time? Let’s explore using Mini 4WDs as example.
Friction
What is friction? Do you know how it relates to the weight of the object you are trying to move?
