A technology not only allows wheels to know when and how to rotate, but also enables them to work together in interactive teams. Simply monitoring the data generated when the motors inside the wheels rotate allows the motors and the wheels to be controlled without the need for any additional sensors.
The researchers were able to observe how the electromagnetic field is distributed at particular locations within the motor, and how this field changes while the motor is running. Introducing the technology into multi-wheeled applications enables wheels to be controlled individually. A tiny microcontroller gathers the data from the individual drive motors and then calculates when and with what power a particular motor needs to switch on.
