Simple two-legged inchworm-like robot. Muscle-wire (shape memory alloy) is used for actuating. Small bristles on legs are used for creating a difference of friction.

Well, yeah, but I’m adding a li’l fireworks to it. 🙂(O ya, it’s the ohmic heating that actually makes the wire try to revert to its original shape; it doesn’t simply contract.)
Also just payed attention to that guys username. “PacoBell”, LOL.

He’s not talking about being shocked by the wire, when Nitinol has a current flowing through it- it contracts. So the method of death adisharr describes is strangulation- not shock.True, but the …
True, but the resistance of your body means it’ll take a fair bit of voltage to do it. To kill yourself on 24VDC would probably require a pair of probes be stabbed into your chest.Not a half bad idea, in this case.

Doesn’t really matter. It isn’t the voltage that kills you, it’s the current.im bored~

DONT READ THIS Cause? It Really Works. YOU WILL GET KISSED ON THE NEAREST POSSIBLE FRIDAY BY THE LOVE OF YOUR LIFE. TOMORROW WILL BE THE BEST DAY OF YOUR LIFE. HOWEVER IF YOU DONT POST THIS COMMENT TO AT LEAST 3 VIDEOS YOU WILL DIE WITHIN 2 DAYS. NOW UV STARTED READIN DIS DUNT STOP THIS IS SO SCARY. SEND THIS OVER TO 5 VIDEOS IN 143 MINUTES WHEN UR DONE PRESS F6 AND UR CRUSHES NAME WILL APPEAR ON THE SCREEN IN BIG LETTERS. THIS IS SO SCARY Cuz IT ACTUALLY WORKS THIS reaLLY WORKSYou left out a k. …

Yes, simply wrap it around your neck a few times and then attach a 24VDC source.It can’t.
It can’t.I wonder whether …

what you need to do now is attach in series a batter, and a blinking christmas tree light to the terminals you created to make it untethered the battery will supply power, and the christmastree light is the cheapest and smallest interval switchthat is a good job~~
that is a good job~~most excellent

Thats awesome didnt expect that.
Your next goal to the “WormBot”.
Is to make it wireless!Good Luck.

5% is enough. I use flexinol 100 in this robot. All flexinols have same contraction. Flexinol is connected to the end of front leg, then is drawn around the middle pin (bolt) and the other side of flexinol is connected to the rear leg. Flexinol is long enough to make this motion. Between the legs you can see the spring for elongation of flexinol after deactivation.
There was a simple circuit with PIC12F675 for driving, but you can use NE555 for switching on/off or just buttons for manual controlvery cool…I just …
very cool…I just purchase .008 inch flexinol (nitinol muscle wire) and the max compression of the material is 5% of the original length, while in your video the wire compresses way more than 5%…. I am thinking of changing materials after seeing your video and was wondering about the price, circuits set up and power source used to run the robot. thank you so muchneat, its a start …
neat, its a start to something huge i betits like a worm
…
its like a wormof plastic … lol
