Fifth grade students build hydraulic robotic arm

Fifth graders worked together to build a hydraulic robot.

Mrs. Stuka’s fifth grade class has shown collaboration and cooperation by building a hydraulic robotic arm. They did this by working in construction crews. Each person signed up for one out of six construction crews. Each crew got a turn to work on the robotic arm during WIN time. It took six sessions to complete the arm. Each day one crew got a turn  to work on the robotic arm for about 30 minutes. There were four to five people in each crew.
How did we build the robot? Well, we read the instructions and followed them, but we also used background information. We had to put together all of the wood pieces and then glue them. We had to fill the tubes with water, then we attached the tubes to the syringes, and finally the syringes to the wood claw. Then, we had our finished hydraulic robotic arm!
How does our robot work? Well, there are three syringes. Two of them make the robot move from side to side and up and down. The third syringe makes the claw open and close to pick up materials such as markers, pencils or even bigger objects.
• The middle syringe makes the robot move up and down.
• The right syringe makes the claw open and close.
• The left syringe moves the arm from side to side.  
Now, the building and testing processes are over, and the class is working on creating works of abstract art with the hydraulic robotic arm. Working with the same construction crews, we took sheets of paper and placed them under the robot. Next, we put colored markers in the robot’s claw and moved the machine from side to side to draw pictures on the paper. We call this process “Robot Art.” Our creations are displayed in the 5th grade hallway.
Mrs. Stuka’s class has shown collaboration and cooperation in building a creation for all to enjoy.
