Three Level Climber Design

[Hugh Meyer]

This design is one that our team decided not to use, but I thought it was good enough that I did not want to just let it die. By posting the design here I am hopeful that it might help some team. You are welcome to use it however you wish.

If anyone out there would like to start modeling in inventor an open source model, I will host it on a SVN server making it available to anyone that wants access.

If you want to actually build this and need help I will do my best to help you through the finer details.

If you have any questions, post them in this thread.

Good luck to all teams!

Thank you for sharing. It is a somewhat complex (or maybe intricate) design, but at a minimum, it should give teams some good ideas.

Better than anything we've come up with.

I believe a side view of the robot (just a drawing) in its different stages would help greatly in understanding how this works.

If I understand correctly what this is, we looked at something similar during the first couple days.

I must say it is a great design and we have the manufacturing capabilities to do it, we just found something that was more in the Pigmice style (involving massive pistons).

Good luck and thanks for sharing.

Similar to a design I thought of. I just wonder what your thought was for keeping the bot from rotating backward when you put downward pressure on that first rung, 'cause I couldn't convince myself I could prevent it.

The weight distribution of the robot would need to have the center of gravity such that it tilts forward to engage the top fingers to the 2nd level bar. Mounting the battery in the front of the robot should help this. If you look at the robot in 3 days videos they talk about this in their design. As you see on the list of negative features, you have correctly identified one of the "tricky" parts of this design. If you notice mounting flanges are oriented such that the system can be mounted at any location on the frame. This will allow the option to experimentally determine the best position using clamps before committing to drilling the mounting holes.
