This project is a bluetooth padlock that can be opened with both your phone and smart watch. It’s an interesting project both from the electronics as well as the different machining operations necessary to make the casing and lock. The ability to not have to deal with a key or a code to punch in really makes it a worthwhile product.
I was particularly interested in the method of converting the physical movement of the person to an analogous movement with the robot. There is much research being done into creating human augmenting robots, but I have never really considered the possibility of having the robot controlled remotely by actual human movements. I wonder if haptic feedback could be added to something like this by looking at resistance of the servos somehow. This could, perhaps, be done by recording the speed or drawn current of the servos. I also believe for any practical uses, a more refined actuation method is necessary: controlling each joint individually. There are a wide range of applications for a similar control method.

]]>I think it’s a neat project because I like the idea of showing the water level using…a water level! It’s a very one-to-one representation of the world.
If I were to make my own version, I’d probably want to use a better valve system—it seemed like the one shown in the video wasn’t reliable enough to keep the water level where it should have been at all times. (Instead, it bounced above and below the set point.)
