I modeled an arm for the robot and assembled the components. It is powered by an HG90 servo motor and is very well-suited for picking up objects.
I created half of the black line for the challenge course, verified and adjusted the precision of every component on the robot, added a TCRT5000 IR sensor, and created a 3D version of the VEML color sensor.
I finished building the case for the Arduino and H-bridge and added IR sensors.
Case for 9V battery
Case for a dedicated H-Bridge on a 2WD Smart Car: This is only half of it.
