I need help! THis is what i have so far but need more! please help! i want it to go fast too as well! i am using arduino language!

Svstem Overview In this project, your team will build and integrate a mechatronic system using the hardware provided (MakeBlock Ultimate 2.0). The rover, shown in Figure 1, consists of three encoder motors that control the left and right wheels and the elevating arm, a gripper that is controlled by a servo motor, and an ultrasonic range sensor. The ultrasonic sensor is attached to the rover on a universal mount with its base rotation controlled by another servo motor. The rover is controlled by an Arduino Mega (ATMega2560) integrated with a motor driver, voltage regulator, and an IO extension board. motor driver, voltage regulator, and an 1'O extension board. Figure 1. Complete MakeBlock Ultimate 2.0 autonomous kit with gripper arm and ultrasonic sensor. Obiective In this project, your team will integrate an autonomous control algorithm with the Arduino to navigate the rover through a maze as fast as possible without a wall collision using the distance information obtained from the ultrasonic sensor. The inner dimensions of the maze are shown in the Figure 2. At the start position, the rover must pick up an object using the gripper and carry the object from start to finish.
