Laser Clicker

Using some laser cut parts, along with a handful of machine screws and nuts, wire, conductive tape, and packaged inside a take out food tub, you can make a three axis motor controller.

This controller was created as a super inexpensive, easy to assemble way to operate the SeaPerch underwater ROV. This controller allows you to make your own DPDT switches. You can also make the switch part using a different technique, and more standard materials. Continue reading

I talked with her about some of the neat designs and later, picked up a copy of her book Robotics: Discover the Science and Technology of the Future with 20 Projects.

After looking through her instructions, I modified them a bit to make my robot hand a bit more durable and consistent. My main changes were to trace my actual hand for the shape, and to add the paper backing, which makes the fingers fall back into place easily. Continue reading
