More thoughts on the upend version

upend_wheels_magnet

A solution for automatically landing in a maneuverable position: conic wheels

Docking could be done with magnets, so the connection will self-align to a certain degree and navigation will not need to be as accurate.

Option 1: e.g. three magnets (to avoid offset docking) on a rotating plate so that the magnetic orientation can change.

Option 2: one (strong) magnet in the center.
This would mean the robots would not be symmetric, but have a front and rear side. Thinking about it, that can be an advantage: When colliding, the part before the hinge would need an upwards impulse. This might be easier to achieve when it is passive (no actuator) and thus much lighter than the part behind the hinge.

Worth a try, I think.

Thoughts on the Upend version

Some scribbled variations on the Upend idea.

Hinges
The hinge could be either integrated in the robots, or the connection between the robots. I think I prefer the former, because a hinge could make the connection weak.

Falling and landing
A symmetric construction avoids the problem of the robots landing on their back when falling. The robots could also be round (barrel-shaped) so they will – hopefully – automatically turn when landing on their sides.

Staying upright
Maybe the hinge could automatically block when the robot is upended, keeping it from keeling over? The robots could stick together on their flat sides. A connection in the gap (e.g. magnets or a slightly sticky surface) might also help to stabilise the tower.
