Three Level Climber Design

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.
