This morning the mailman had another package for me! It was a padded envelope with nothing less than the 4 Technic axle compatible holonomic wheel prototypes from Rotacaster.
I haven’t had a chance to build anything with them but my first impressions are:
- Very compact, they’re about 3.5 units wide and about 6 units in diameter;
- Quiet! They’re all plastic, that means no noisy metal frames to hold the sub wheels;
- Smooth ride, they’re very round;
- Slightly bigger than the NXT 2.0 wheel and slightly smaller than the 1.0 wheel, so no motor clearance issues.
The white hub inserts are prototyped and still need a little fine tuning; some of the pieces hold the axle a little too tightly, requiring a firm hold to push the axles through. The inserts stay in place in the wheel using a very small key that fits into a narrow gap. I am sure you don’t really care about all this, you just want to see what they look like, so without further ado:
I will try to put together a nice prototype robot with these this weekend. I have 4 of them so I should be able to build some pretty cool models with this. More pictures and a video will follow.
