Team 118 2020 Seson Climb Mechanism

[denizsenol]

Hi guys,

I just wanted to ask if any of you guys figured out how the Team 118- Robonauts 2020 season climber works. I spent a good amount of time but couldn’t get how the climber elevates itself up. If any of you guys have good ideas about low (trenchbot) robot climber mechanisms, feel free to share Thanks…

Steel Tape Drive (for telescoping arm)

Inspired by 118’s reveal video, I tried to design a winch for a telescoping arm based on a spring steel strip. The neat thing about their mechanism is it appears to be able to push the telescoping arm up and pull it down to lift the robot. Usually extending a telescoping arm requires an external spring and cable rigging to extend each of the arm sections. I’m pretty sure they did this with a steel tape on a spool, similar to the tape measure climbers we have seen in the past, but more reliable. …

See above thread for an example of the underlying drive mechanism.
