Not to rain on people's parades here, but.....
***Before I go on, I feel I need to point out that I do have experience with Mecanums. 2 years. 1.5 years driving***
- In that first video, some on the other side is holding the ramp up (or down, however you look at it). Now, I can't prove it, but I'm pretty darn sure that that helps the robot get up.
- It took a long time to get up that ramp. Too long.
- 1 out of 5 times that drivetrain will probably fall off, unless you go super slow, which in that case see Bullet point #2
- What happens if for some reason you can't go over the bridge that round? Mecanum's will have an extremely hard time maneuvering the ridge.
- The material on that bridge was different than that of in the real game
- In the second video, the Mecanum's were having a very hard time getting up the bridge (not too sure how it helped Mecanum's case). If anything, it shows that carefully done programming will be required just for your drivetrain.
- The more top heavy these robots become, the harder it will get.
- A preponderance of team's this year will have a strong hard pushing robot. Good luck scoring on one. It's not fun.
Please take my criticism in a constructive manner, as I will do the same.
