Hydraulic powered robotic arm from cardboard instructions

You will need to start by designing your robot arm. The six common types of robot arm are shown below. For this challenge the articulated robot arm is the most common solution. Your teacher will guide you through an exercise in designing your arm. Once you have a design that works, sketch it at ½ scale using the back of this handout. 16. 16 Robot Power The power for a robotic arm can either be electric, hydraulic, or pneumatic. Hydraulics is putting liquids under pressure Pneumatics is putting gases under pressure. The power supply acts like the robot's heart and muscles. It provides the energy for pushing, pulling, turning and lifting. Students design and build a mechanical arm that lifts and moves an empty 12-ounce soda can using hydraulics for power. Small design teams (1-2 students each) design and build a single axis for use in the completed mechanical arm. One team designs and builds the grasping hand, another team the lifting arm, and a third team the rotation base. The three groups must work to communicate effectively Your hydraulic system is finished. Step #11 Insert a screw into the hole aside the cylinder tips to keep the tubing from pulling off. Have you repeated steps 8-12 to create the hydraulic systems listed below? If so, continue to the next page. Your hydraulic system will not work well if air is in the cylinders or tubes. Procedure 1. Trace a hand onto cardboard and cut it out. 2. Cut straws into 1-inch pieces (or 1/2 inch if you have a small hand!). 3. Using the tape, attach the straw pieces to the hand (see top image). 4. Crease the cardboard in between the straws - these will simulate your joints (see red lines on top image). 5. By making two bases, you'll be able to flip the Hydraulic Arm and use it in two different positions. Assemble the two bases and the post using the two wood screws. Countersink to make sure the heads of the screws don't stick out from the top and bottom bases. Attach the arm to the post using a machine screw, three washers, and a wing nut. DESCRIPTION The Hydraulic Machines 4-in-1 Pack brings four wooden machines to life with hydraulic power. Learn how to use water pressure in syringes and rubber tubes to control a platform lifter, a scissor lift, a cherry picker, and an excavator. Built from pre-cut and pre-drilled wooden parts, these machines will provide hours of fun and hands The design of this arm is very simple and only uses three motors: The base motor - This rotates the arm around. The first arm motor - This raises and lowers the base of the arm. The second arm motor - This raises and lowers the forearm. The construction of the arm is simple. Therefore, other aspects of the arm may need to be considered. arm x 2 bottom syringe piece spacer x 2 big spacer x 6 small spacer x 4 supporting platform x 2 gripper body x 1 hole for the wire 2 Code: 29209 This DIY kit contains everything needed to assemble a model robot grabber arm that makes use of hydraulic power to open and close the hand.
