DEWBOT XIV Lift
- Ability to score via scale, switch and exchange
- Ability to score in "lost" scale on 2nd level (defines scoring height)
- Ability to rotate arm to back to score in autonomous without having to turn around
- Lift time from pick-up to scale scoring ~ 1 sec
The lift is a 2-stage, single center post, cascade design. The main structural elements (stage 0 & 1) comprise 80/20 2020 profiles with 80/20 2752 roller wheel brackets. The 2nd stage comprises a carriage with arm drive, arms and roller claw.
The objective of scoring from either the front or rear of the robot (to facilitate autonomous scoring) drove the selection of a center post approach. The arm is able to rotate above the top of the lift when the lift is raised and allows the robot to score in the scale from the robot's rear. Earlier concepts employed a conventional frame lift with the thought that the claw could translate within this frame, but calculations revealed that passing the claw through a frame that fits on the short axis of the robot was impractical.
