The NXTolaus is a Christmas robot that can be built with a single LEGO® MINDSTORMS NXT 2.0 set.
When roaming around with a closed bag full of presents, it will detect you with its Ultrasonic sensor. In that case, it will stop, speak some Christmas greetings and open its bag.
Once you have taken out the presents, the NXTolaus will notice that using a hidden touch sensor at the bottom of the bag; it then closes the bag and “walks” away.
The building instructions can be used in LEGO Digital Designer.
The cables are connected as follows:
- The motors that drive the tracks: Ports A and C
- The motor that opens the bag: Port B
- The touch sensor: Port 2
- The Ultrasonic sensor: Port 3
- The color sensor: Port 4
