Wenn Sie etwas nicht ganz verstehen, kann ich Ihre fragen auf Deutsch beantworten.

So far, I’ve had a bit of a challenge with the treads – but printed some 2.30mmx2.30mmx9.70mm block inserts to keep them from falling apart. The blocks work like keys in the similarly shaped holes to keep the “H” pieces from falling out.

Thanks, I’m happy you’re enjoying building my Wall-E design (don’t forget to share some pictures once you are done!). The Eve design sounds plausible, controlling pitch and roll with the servo fins and yaw using the differential props; very similar to an RC helicopter. It would be a very challenging build from a mechanics and control prospective, and you will need to use very strong (and noisy) fans to produce enough thrust for levitation. For a project like that I’d encourage you to build a test assembly of the ducted fan first so that you can test its performance, before building Eve around it.

I’ve also been thinking about building another robot from Wall-E: “Mo” the cleaning robot. The robot balances on one single wheel, so it would also be an interesting robot to build. I found a research paper which describes the mechanics behind ball balancing quite well. However, it may be another year or two before I find the time to start the project…

I am working on printing the parts right now and look forward to bringing a Wall-E to life for my kids.

I am also big on learning how to use gyro and accelerometer sensors – I believe I’d like to attempt single ducted-fan levitation (twin prop, single shaft), with servos directing thrust via upper and bottom fins to balance the robot. The ‘Eve’ robot from Wall-E may be my first attempt – the shape from top to bottom is perfect for such a design.

What do you think?
