Level up a finished Arbot with three upgrades in one pack: an SG90 Micro Servo 4-Pack for grippers and moving parts, an IR Line-Tracking Sensor 5-Pack for the 8th challenge (line following), and an HC-05 Bluetooth Module so students can drive their robot from a phone. Everything works with the Arbot's UNO R3 board and our free base code. Save over 10% versus buying separately.
