Crawler Challenge: Building Rope-Traversing Robots

Rope-climbing robots are the stuff of engineering dreams. As kids, didn’t we all clutter our family home with constructions of towers and strings – Meccano, or Lego – to have ziplines spanning entire rooms? Good for the youngsters of today, this has been included in school curricula. At the University of Illinois, the ME 370 students have been given the task of building a robot that can hang from a rope and walk across it—without damaging the rope. The final projects show not only how to approach tricky design problems, but also the creative solutions they stumbled upon.

Imagine a tiny, rope-climbing walker in your workshop—what could you create?

The project is full of opportunities for those thinking out of the box. It’s all about the balance between innovation and practicality: the students have to come up with a solution that can move at least 2 meters per minute, fits in a shoebox, and has some creative flair—no wheels allowed! The constraints provide an extra layer of challenge, but that’s where the fun lies. Some students use inverted walkers, others take on a more creature-like approach. The clever use of motors and batteries shows just how far simple tech can go when combined with a bit of engineering magic.

This project is a fantastic reminder that even small, seemingly simple design challenges can lead to fascinating creations. It invites us adults to play, and by that, we learn: a win-win situation. You can find the original article here, or grab some popcorn and watch the video below.

Robotic Falconry: Winged Unit Lands On You!

It doesn’t have four rotors, but this advanced-glider is every bit as impressive as the most complicated of quadrotor offerings. It’s the first glider that can successfully perch on your arm. We can’t help but think back to the owl in the original Clash of the Titans movie.

The team at the Aerospace Robotics and Control Lab of the University of Illinois at Urbana-Champaign is happy to show off the test flights they’ve been conducting. We’ve embedded two of them after the break which show the unit landing on this person’s arm, and on the seat of a chair. The image above shows a montage of several frames from the flight, and gives us a pretty good look at the articulated wings. You can seen them both bent in the middle of the flight to zero in on the landing zone. In addition to this there are flaps on the trailing edge of the wings and tail. The flight path is a bit wandering since the glider has no vertical tail to stabilize it.

Now if they can make it harvest power from overhead electrical lines they’ve got a spy-bird which can be dropped from a plane (or from a drone).
