Supersonic 5 Minute Lego Bot

In order to experiment with our new YAKINDU SCT4NXT statechart tool for Lego Mindstroms NXT i was looking for a simple Lego bot that can be build within few minutes. I came across the building instructions of the 'Five Minute Bot'. This was a good basis for and just had to attach the desired supersonic and touch sensors.

It looks like this ...




... and here are the building instructions.

The design is based on the ‘Five Minute Bot’ from www.nxtprograms.com. So start with those building instructions and continue here when you are ready…

Mounting the ultrasonic sensor

For the ultrasonic sensor you’ll need the sensor itself as well as few other parts.
step one
step two
step three
step four Now first connect the cable and then mount the ultrasonic sensor to the bots bottom side.

Mounting the touch sensors

Mounting the right and left touch sensors are identical so the instructions below are for one sensor and you have to build it twice.

Each sensor needs some parts for attaching it to the bot as well as some part that are mounted on the tip of the sensor in order to have a larger touch area.
step one
step two For the left sensor the mounting bar has to be attached to the other side of the sensor.
step three
step four connect it to the right (and left) side of the NXT brick

… done !!

The bot should now look like this ...
