Motorized Crane made from PASCO Structures
See the Product Description for this item's included accessories.
See the Buying Guide for this item's required, recommended, and additional accessories.
Product Summary
The Motorized Crane is made using PASCO Structures and is controlled and powered by the //control.Node. Students can program the controller to run the stepper motor and servo motors using Blockly coding embedded in PASCO Capstone or SPARKvue software.
The crane picks up objects with an electromagnet which is also controlled and powered by the //control.Node. Students can vary the duty cycle to change the power of the electromagnet and explore the minimum power required to pick up different objects. Steel washers are included with stickers to attach to non-ferrous objects, such as paper cups, so the electromagnet can pick them up.
The crane includes three sets of gears to explore the effect of gear ratios (1:1, 2:1, 4:1) on speed and lifting capability.
Features
- The controller can execute its code via Bluetooth or USB connection to a computer or autonomously via uploaded code.
- The motors and electromagnet on the crane are powered by the rechargeable battery in the //control.Node.
- The position and speed of the stepper motor and electromagnet can be displayed in the software while the code is executed.
- The cable spool has two diameters to learn about mechanical advantage.
- The //code.Node accelerometer is used as a joystick to move the crane so the crane can learn the locations of certain positions.
- Students build the crane and can change the design using additional Structures parts.
- Any PASCO sensor can be used with the crane to expand its capabilities.
Perform These Experiments
- Build the Motorized Crane
- Introduction to Stepper and Servo Motors
- Position Boom Angle and Electromagnet Height to Reach a Position
