Powered Up 3 Speed Automatic Gearbox

The lego technic Powered Up motors and functions have been used to create a lego technic 3 speed automatic gearbox. With the lego Powered Up functions you can accurately control motor speed and motor position, as well as being able to measure the angular position of a motor. These new possibilities have been used to create a three speed automatic gearbox.

One motor is used to measure the torque at the output of the gearbox by detecting the rotation of an output differential; another motor is used to accurately set the position of an orange rotary catch controlling the switching between three forward gears, and finally one large powered up motor is used to drive the gearbox. The gearbox implements 3 forward speeds at gearing ratios of 1 to 1, 1 to 0.6 and 1 to 0.2 as well as one manual reverse gear.

The Lego Powered Up app has been used to program the gearbox controller on an iphone. Thanks to @racingbrick (racingbrick.com) for providing a great guide to all of the available programming blocks.
