A LEGO Technic remote controlled cross-drive transmission with high/low range, double differential steering, forward/reverse, and land/swim mode. This is designed for tracked vehicles which can operate on land and also swim in the sea. The first part of the video is the demo, while the second part shows how it works. Enjoy!
Could you please make building instructions or an LDD file for this? I've seen the video, and I understand how steering with 2 differentials would work, but building frames and stuff is not my strong point. I just want to see either one.
