Others Like “Grasping with Straws: Make a Robot Hand Using Drinking Straws”

Science Fair Project Idea
thumbnail Imagine how cool it would be to have your own motorized robot hand. Well, stop imagining and turn that daydream into reality! Start out by designing and building a robot hand. The Science Buddies project shows you a simple way to make a robot hand with drinking straws, or you can design a robot hand from any other materials you think are suitable. Your hand design will need sewing threads, or some other mechanism, for motors to act on and move, causing the fingers to flex. See Figure 1… Read more

- Less Details
Time Required Long (2-4 weeks)
Prerequisites Once the hand is assembled, adding the servo motors, connecting the microprocessor, and writing the code for the microprocessor will require familiarity with a hobbyist microprocessor board (like ones using [# ProjectGuide Name="ProjectGuide.Robotics.Arduino" Value="HtmlAnchor" HtmlText="Arduino" #]TM, PIC®, or similar). The student should be comfortable with connecting, programming, and testing projects on these boards.
Material Availability Readily available
Cost High ($100 - $150)
Safety Adult supervision is suggested for parts of this project. Use caution with sharp knives, glue, and soldering. Low voltage (from a battery or power supply) is involved.

thumbnail Alternative energy sources are a big deal these days. One such source is the wind. Find out how a wind turbine can use the power of the wind to generate energy in this science fair engineering project. You'll design various blades to find out which produces the most energy, and put the wind to work for you! Read more

Science Fair Project Idea
thumbnail Have you ever broken a fishing rod? Or seen a treetop bend over and touch the ground (or even snap off) during an ice storm? These are examples of the effect of bending stresses on flexible rods. There are scientists who actually study this phenomenon and discover ways to prevent breakage, which leads to stronger fishing rods, building materials, car parts, and more. In this science project, you'll explore the bending stresses in flexible rods by testing asparagus stalks. Read more

thumbnail Suspension bridges, with their tall towers, long spans, and gracefully curving cables, are beautiful examples of the work of civil engineers. How do the cables and towers carry the load that is on the bridge? Can a suspension bridge carry a greater load than a simple beam bridge? This science project shows you how to find out. Read more

thumbnail Robots come in many shapes and sizes. From the Mars Rovers to toy dinosaurs, robots are well-planned machines designed to suit their individual purposes. In this science project, you will test different robot designs with an online simulator made up of dots and lines, much like bendable soda straws. How will each robot design respond to changes in their conditions? Read more

Science Fair Project Idea
thumbnail Have you ever wondered how a radio can grab signals that are transmitted through the air and convert them into sound? In this science project, you will build your own AM radio receiver from scratch and use it to listen to AM radio broadcasts. With your crystal radio you will be able to experiment with the circuit and the antenna to get the best reception. Read more

Time Required Average (6-10 days)
Prerequisites To do this science project, you must live in an area where you can receive at least one strong AM radio station. You can check for this with a car or portable radio.
Material Availability Specific circuit items are required. A Science Buddies kit is available for your convenience. See the Materials and Equipment list for details
Cost Average ($40 - $80)
Safety Never operate your crystal radio during a thunderstorm. When not in use, always disconnect your antenna from the radio circuit, and connect it directly to the ground rod. Be sure to wear safety goggles when installing the ground rod, especially if you are using a metal hammer. An adult's help might be necessary for some steps in the Procedure.
Science Fair Project Idea
thumbnail Have you ever seen moths buzzing around bright lights at night? What about animals that always crawl into dark places, under rocks or furniture? This type of behavior is called phototaxis — movement toward (or away from) a light source. In this project you will build your own biologically inspired robot critter that mimics this behavior. Basing your design on the popular and simple BristleBot robot, you will make a robot with two light sensors for "eyes" and two motors that help it steer… Read more

Time Required Average (6-10 days)
Prerequisites Some familiarity with electronic circuits and using breadboards will be very helpful, though not required, for this project. Using a soldering iron is also helpful but a work-around is offered in the Procedure.
Material Availability This project requires certain parts from an electronics store or online retailer. See the Materials and Equipment list for details.
Cost Average ($40 - $80)
Safety If you use a soldering iron for this project remember that soldering irons get extremely hot and can cause burns if they touch your skin. They can also become a fire hazard if left unattended. Science Buddies recommends using lead-free solder, especially in homes with pets or small children.

Science Fair Project Idea
thumbnail When you think about robots, chances are they are contraptions that you have seen on TV, in movies, or even in real life — and they are usually made of metal. What if you could make a soft robot that could bend, twist, or squirm like an octopus or an earthworm? Researchers at Harvard University have done exactly that, developing soft robots made of rubber and powered by air instead of electricity. In this project you will use their designs to build a soft robotic gripper of your own. Read more
