I am trying to design a robot to lift tote-crates and transport them around in a localized area. I want to be able to carry 3 tote-creates at a time. This robot needs to be able to pickup the creates. I only want the robot to carry three at a time so keep is small and mobile. I was thinking of a design with a central lift that could carry the crates. What would you suggest as a simple ingenious way to create this robot?

We prefer practical, answerable questions based on actual problems that you face.

The simplest way? Every crate has its own wheels and motor. In other words one robot per crate. I bet that in some cases this is lower cost. It certainly lowest the design complexity.

The other design is a "travel lift". These are used on boat and lumber yards. You would build a smaller version. It is the shape of an inverted "U" with four wheels. It looks like an overhead crane, the kind the runs on an overhead I-bean track but the I beam is on wheels. Then you place three lifts on you mobile I-beam track. The robot could stores three crates, if the I-beam where longer it could store more.

You crate ned a handle that a lift can capture. A magnet might help to initially align the parts and then close a mechanical latch.

like the one robot per crate idea as being fool proof simple.
