WORLD’s FASTEST Naked Egg (Rubber Egg, Bouncy Egg) Experiment

In Atal Tinkering Labs ATL | No comment

I’m going to show you how to make a naked egg lighting FAST. When you use Calcium, Lime, Rust Remover (CLR) your naked egg will be ready in under 2 hours. Make sure you read the cautions on the container. I used gloves, in a ventilated area and googles. Adult supervision is required.   CLR is guaranteed to be the easiest and fastest method of quickly dissolving calcium. Hence the name Calcium Lime Rust remover.   The reason the egg shell dissolves in White Vinegar, Red Wine Calcium, Lime, and Rust Stain Remover is the Acid breaks apart the calcium…

EPIC Naked Egg fold, toss and shape! (Rubber Egg, Bouncy Egg)

In Atal Tinkering Labs ATL | No comment

If you have done the Naked egg experiment before, your going to love this experiment, as we take it to the next level.   Only different on set up is you use a pushpin to make holes on both ends of the egg. Then use a skewer to break yolk. Be careful not to break the shell. Then use Vinegar or CLR (See below where to buy) CRL will remove the shell in under 2 hours, where vinegar takes 24 to 48 hours. (See Lighting FAST Naked Egg video below) You will never use vinegar again.   Then blow out…

Can You Walk on Water? (Non-Newtonian Fluid Pool)

In Atal Tinkering Labs ATL | No comment

15 boxes of Cornstarch and were walking on Oobleck! Mix one box at a time in a separate bowl and then poured into the tub.   What is happening? You’ve essentially made homemade quicksand or a large tub of oobleck. Corn starch in water displays interesting properties. Under some conditions, it behaves as a liquid, while under other conditions, it acts as a solid. If you punch the mixture, it will be like hitting a wall, yet you can sink your feet or body into it like water. If you squeeze it, it feels firm, yet when you release the…

How close are we to having robot companions?

In Robotics | No comment

Will advances in artificial intelligence bring us closer to having robots in our homes? A Michigan Engineering expert weighs in on the goals and outlook for research in making robots that think like humans.   The idea of artificial intelligence is rooted in creating a mind that has the same flexibilities and capabilities of a human mind — or even more. Although research has been advanced in a variety of areas of human intelligence, such as voice and face recognition, the next question will be how to integrate the separate aspects into a fully capable brain, says U-M professor Satinder…

Bipedal Robot MABEL Walks Over Randomly Varying Ground

In Robotics | No comment

Bipedal Robot MABEL Walks over Randomly Varying Ground: Experiment No. 1 Challenge: Traverse an irregular surface without prior knowledge of ground profile. Comments: We used a single feedback control, with a virtual compliant term in the stance knee. Switching control is not employed here. This was our initial attempt over random ground. The robot fell at the end of the experiment. We understand why it fell and will be back with more results soon.

Preliminary Outdoor Walking with Underactuated Bipedal Robot MARLO

In Robotics | No comment

Testing done on Saturday November 23, 2013 at 8 AM in front of the EECS Building on the University of Michigan North Campus. The temperature was -2 C (about 29 F). MARLO is an underactuated 3D bipedal robot with passive prosthetic feet. Its feedback control is designed using virtual constraints. In previous experiments, MARLO was attached to a boom. but with improved control, the robot can now walk without any external support. A mobile gantry supports a safety cable to catch the robot when it falls, avoiding expensive and time-consuming repairs. The robot is one of 3 ATRIAS-series robots designed…

MARLO: Dynamic 3D walking based on HZD gait design and BMI constraint selection

In Robotics | No comment

BTN LiveBiG was filming MARLO the day we began testing a new method for controller design.   The controller is based on virtual constraints and hybrid zero dynamics (HZD). Here we are testing a new method for designing virtual constraints based on bilinear matrix inequality (BMI) optimization.   MARLO is a 3D robot designed to study principles of dynamic walking. Unlike most other 3D walking robots, MARLO does not have large feet with powered ankles. This forces the robot to balance dynamically, but may lead to more natural and more energetically efficient walking.   MARLO is one of three ATRIAS…

From running roaches to robots

In Robotics | No comment

U-M engineers are analyzing the reflexes of cockroaches to aid in developing steadier robots. Professor Shai Revzen is recording the reaction of running cockroaches being shoved sideways, discovering that their body kicks in before their dawdling nervous system can tell it what to do. These new insights on how biological systems stabilize could one day help engineers design steadier robots and improve doctors’ understanding of human gait abnormalities.
