Wheels
- 105 mm wheel from an old Vex kit =>
- 330 mm circumference
- 330 mm/rev * 160 rev/min =>
- 53 m/min or 0.9 m/sec
- 53 m/min / 1610 m/mile * 60 min/hr => 2.0 mph
- Wheeled Platforms "... 1 m/sec is pretty fast for indoor robots."
- Take-away - This is one of the reasons this configuration is hard to control.
