Week 8 Update - Reading Week Update

A significant amount of progress has been made over reading week.

The motor control system has now been fully integrated and includes the following functionality:

- using the ultrasonic sensor, the robot can drive straight along the row at a consistent distance from the row and can make corrections as it drives off course

- using the camera, the robot can drive until it has aligned the tooling arm position with the a ripe spear (tall enough) and then return the depth into the row of that spear
