A Climbing Robot with Long Extending and Bending Tape Measure Limb - EEWOC

EEWOC: Extended-reach Enhanced Wheeled Orb for Climbing
Our modern world is filled with many large vertical structures, including towers, factories, bridges, power stations, and ships. These vital pieces of infrastructure require regular inspections and maintenance to ensure safety, but can be dangerous for humans. Climbing robots can be deployed to help protect human inspectors from electrical, chemical, and fall hazards, and can help automate these tedious and labor-intensive tasks. Existing climbing robots generally use wheeled locomotion, which offers poor adaptability and cannot overcome small features, or legged movement, which are often slow and bulky due to their overly complex designs that mimic ground-based animals and manipulator arms.
EEWOC uses a unique locomotion scheme to climb complex steel structures with its magnetic grippers. Its lightweight and highly extendable tape spring limb can reach over 1.2m, allowing it to traverse gaps and obstacles much larger than other existing climbing robots. Its ability to bend allows it to reach around corners and over ledges, and it can transition between surfaces easily thanks to assistance from its wheels. The wheels also let it to drive more quickly and efficiently on the ground. These features make EEWOC well-suited for climbing the complex steel structures seen in real-world environments.
EEWOC fits within a 260mm diameter sphere and weighs only 2.1kg. It can travel at 0.24m/s (0.79 ft/s) or around 0.9 bodylengths/s, making it one of the fastest climbing robots. It can also lift 3.4kg with a payload-to-weight ratio of 1.62, also making it one of the strongest. Its long limb length helps simplify the process of identifying suitable grasping points and coordinating limbs, steps which cause other legged climbing robots to be very slow. EEWOC represents a minimalist morphology that reduces the actuators and structures necessary for climbing, using passive, compliant, and switchable mechanisms.

is this the new penguin from Wallace and Gromit?

[@makerzip]

The part where magnets are used to simulate Spider-Man's abilities is really creative and innovative. I think it's cool.

[@designbyarchitect4603]

Amazing!

[@Blockistium]

i love the sounds it makes

[@0hellow797]

Hahaha so sick, love the tape haha

[@pionnierancetre5173]

really cool

[@norbertfeurle7905]

I can make you guys an electrostatic gripper so that it can climb almost any wall.

[@sjl949]

This is extremely creative and novel, future vision seems really cool as well

[@bramha_labs]

Basically you guys are making spider man robot 😂

[@justin_quan]

Ahaha yeah that's pretty much it, with the wall-climbing and swinging! 😂

[@justin_quan]

Except Spider-Man can only shoot his webs straight and can't bend them around corners! 😉
EEWOC: 1, Spider-Man: 0

​@@justin_quanare you in the team of romela ?

[@bramha_labs]

@@justin_quan I've messaged you on Instagram

[@glennzircalt2254]

will gecko tape be used for gripers maybe

[@user-eh4pm7bb6o]

와 ㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋ
