Re: Best Drivetrain options
I went through the following decision process:
What technologies do we have a comfortable level of experience with? Tank - yes Mecanum - yes Shifting - yes Single speed -yes Slide/H/octanum - no Swerve - no Advantages synergistic with proposed play style? Mecanum - translation, non-rocking base of support Tank - non-rocking base of support, (arguably) lower weight Shifting - none, divided field means acceleration in short runs will be most important feature Single speed - lightness, simplicity, low cost, with so many motors available we can add power until we like the performance Since mecanum's classic disadvantages aren't a serious issue with recent upgrades from mecanum wheel makers and the lack of robot-robot defensive play (at least in my humble opinion) mecanum, with single-speed transmissions, won out for us. YRMV given different team experiences or preferences. We already have a prototype mecanum drive slapped together to get the programmers and drivers practicing! |
