WARNING [DO NOT TRY THIS AT HOME!]
NXT-sans Underwater Excavator
John Brost is showing the NXT-sans, a LEGO copy of the Nexans Spider, build to excavate underwater.
The model was build By Daniel, Martyn (aka Robotica) and Eric, in the Netherlands, for demo during NI Week 2008.
The real Spider works with an Compact RIO controller by NI, this one has 2 NXT running NXT-G or Labview.
This model has 5 XL PF motors to scoop, turn and drive. Form the remote you can turn on custom LED lights.
During the first day of the event 2 motor had to be exchanged because they stopped working. YES the motors are Running UNDERWATER, but are not watertight, they are more water resistance. [DO NOT SUBMERGE YOUR MOTORS OR NXT AT HOME, because LEGO® does not replace your motors!]
It took us about 100 hours to build an program the model.
