4-Wheel Independent Pivot Drive allows for dynamic and controlled reorientation (twisting) of the chassis in Crab drive mode. The mathematics behind two different Crab twist modes are exploreed.
Basic mathematics behind the control of an 4-wheel independent Pivot Drive-Train. A companion paper, Crab-with-a-Twist, describes the math needed for twisting crab-drive on the move.
Spreadsheet to calculate time for a Flywheel to spinup to speed. Wheel and motor characteristics are customizable. Also has code for calculating spinup assuming an optimally shifting transmission with up to 3 gears.
a californian combat robot builder contacted me through chiefdelphi and asked me about mecanum wheels. now im designing wheels for a 3lb mecanum flamethrower bot. here's the teaser shot.
Yes, i cheated the Nylon 4-40 screws they get razorknif'ed off
This is a document concerning robot steering. It explains the numerous steering modes for Team 79’s robot, Captain Krunch 6. This robot uses a crab-drive design.
We developed these steering modes in 2003 and 2004.
This is a tool I use to get my chain adjuster travels right and to give my "gut" a chance to "see" the chain path before I commit to it in metal (I like to judge the amount of chain wrap around a sprocket visually).
It is not a perfect tool. It does not have any way to en...
