21st Century Connections for Manual Grabber

Learning and Innovation Skills

Critical Thinking and Problem Solving

• Make judgements and decisions • Solve problems

Use Manual Grabber to help students solve real world problems. Give students opportunities to brain-storm and try to implement a solution to a real-world problem. For instance, encourage students to consider how robots such as Manual Grabber can help clean up oceans. Why are dirty oceans a problem? What changes could be made to Manual Grabber’s design to help make cleaning the ocean easier?

Information, Media and Technology Skills

Information Literacy• Access and evaluate information• Use and manage information

Use Manual Grabber to help students use technology to explore ways Manual Grabber could help in different environments. How would Manual Grabber work in a landfill? Or on ice? What modifications have been made on real vehicles that could help Manual Grabber clean up the Earth? Provide students with access to online resources and have them create a new and innovative design for Manual Grabber, using real heavy-duty machines as inspiration.

Life and Career Skills

Leadership and Responsibility

Use Manual Grabber to help students explore various leadership roles as well as environmental respon-sibility as a citizen of Earth. Provide students with the opportunity to plan and implement a school wide recycling drive. Students will need to assign tasks, delegate responsibilities and document the results after the event has been completed. Encourage students to take personal responsibility for caring for their little section of the planet.

Rotating Joint can be used in another adventure? How do you think the Rotating Joint can work alone?



- What is something new you learned today about the Mabot GO app, Mabot IDE app and code blocks?

- Is there anyway you can think of to make a simpler version of Manual Grabber? Or is there another way you can think of to make a more complicated version of Manual Grabber? What would you want it to do if it was different this way?

Worksheet: - What other Mabot can Manual Grabber work with in an adventure?



Extensions

Math

Weight

Create a lesson that explores how much weight Manual Grabber can hold in its Clipper. Why is it important to know how much weight Manual Grabber can hold? What else do we weigh in the real world?

Dimension

Create a lesson that uses Manual Grabber’s Clipper as the focus. What dimensions are important when Manual Grabber is picking something up? Are different shapes easier for Manual Grabber to hold? How do dimension and weight go together? How can Clippers help people with disabili-ties grip different objects?

Suggested Resources for Planning:

- Have students hold objects of different size and shape with their hands

• Can they still hold them as they get heavier? • Does the shape matter when it comes to holding it?

Engineering

Mechanics

Create a lesson that investigates the mechanics of why and how Manual Grabber works. How do Manual Grabber’s pieces work together to open and close its Clipper? Why is it important to know how much Manual Grabber can open its Clipper? How do real construction workers use mechanics to get the job done?

Movement

Create a lesson that uses Manual Grabber’s movement. How do Manual Grabber’s movements compare to a bulldozer or a fork lift? How can we program Manual Grabber to work like a real construction vehicle?


- Let students take apart a small device like an old phone and examine the mechanical aspects. Ask for parents, or the community to donate devices to use.

- Show a video of a claw machine at an arcade, a crane or a log grabber at work.



Arts

Perspective

Create a lesson about depth of field. How do artists use depth of field to fill their paintings? How does this relate to Manual Grabber’s depth of field when it is trying to grab an object? Do different perspectives change the depth of field, or does it always remain the same?


- Use a camera to explore how clear an image is very close up, or very far away

- Partner with the Art teacher and have students draw pictures that use foreground and background and examine the differences between the two.

Modifications

Code Blocks Used in This Activity

Start This block shows up on the screen automatically. All code blocks need to connect to this block in order for the program to run.

Repeat This block allows the robot to repeat whichever code blocks are nested in it a specified number of times.

Swinging JointThis block allows the robot to move its Swinging Joints at a certain speed to a specified angle.

Code blocks can be connected like puzzle pieces. Students can connect the blocks by dragging them near each other until they attach.



Rotating JointThis allows the robot to rotate a part of its structure. Wheel This block allows the robot to move. Students can make the robot move forward, backward and turn by altering this code block

Guiding Questions

Challenge 1Guiding Questions: What speed should you set the Rotating Joint so that it opens and closes the Clipper so that Manual Grabber can grab the litter?

What direction and angle do you need to bend the Swinging Joint to help Manual Grabber bend and pick up the pieces of litter? What speed should you set the Swinging Joint in order to help Manual Grabber bend and pick up the pieces of litter?

Potential Student Response:The Clipper can be opened at any speed but, fast is best if you want it to open quickly. When closing the Clipper it should close slowly speed to make sure it doesn’t drop the litter it is holding.

The direction of the Swinging Joint should be downward. The angle value depends on how far off the ground the piece of litter is. The Swinging Joint should move slowly so it is able to pick up the piece of litter. If it moves too fast it might drop the litter.

Challenge 2Guiding Questions:Do you think Manual Grabber moves like Skip Car? Why?

Potential Student Response:Manual Grabber moves the same way as Skip Car because they both have four wheels. Manual Grabber’s wheels can be set the same way Skip Car’s were in order to make it move forward.

Challenge 3

Guiding Questions:What direction and angle do you need to bend the Swinging Joint to help Manual Grabber lower and raise the pieces of litter above the recycling bin? What speed should you set the Swinging Joint to in order to help Manual Grabber lower and raise the pieces of litter?

What speed should you set the Rotating Joint so that it opens and closes the Clipper so that Manual Grabber is able to drop the pieces of litter into the recycling bin?



Potential Student Response:The direction of the Swinging Joint should be downward, just like in the first challenge. The angle value will depend on how far off the ground the recycling bin is. The Clipper should not be too high above it. The Swinging Joint should move slowly so it is able to drop the litter into the bin without missing. If it moves too fast the litter could fall back onto the ground.

The Clipper can be opened at a medium speed as long as it is directly above the recycling bin. When closing the Clipper it’s also okay to close it quickly since it is not responsible to grabbing anything now.

Challenge 4

Guiding Questions:Can you use your knowledge from programming Skip Car’s Drive Balls and from Challenge 2 to help Manual Grabber move backward?

Potential Student ResponseJust like in Skip Car, when making Manual Grabber move backward, the direction of the wheels must be the opposite of the directions that make it move forward.



Final Code Example

The final code should look like this, although students may create a different code (i.e. different values and directions) that accomplish the same tasks:



Building

- The 5-Hole Beams may be hard to pull apart even with a Disassembly Tool.

- To access the building instructions on the Mabot GO App, follow these steps:

• Open the Mabot GO App.• Click the yellow ‘Play’ button.• Go to ‘Official Building.’• Click ‘Manual Grabber.’• To access the building instructions, click the ‘Robot Model Introduction’ button at the top

left corner.

- Be careful when lifting the robot because parts may disassemble easily.

- The yellow piece that goes around the Clipper that is supposed to keep the top of the Rotating Joint stationary is very delicate. If it does not hold the Rotating Joint well, the Clippers will not open and close, instead the whole Clipper and Rotating Joint structure rotates.

- Check all connections and make sure all the parts are online.

- After all parts are connected properly, you must click the yellow arrow to pair the wheels and download the program.

Playing

- Go through the configuration and set-up with the class first so that students have seen the process before trying it themselves.

- To play with Manual Grabber and access the control screen on the Mabot GO App, follow these steps:

• Open the Mabot GO App.• Click the yellow ‘Play’ button.• Go to ‘Official Building.’• Click ‘Manual Grabber.’• Students need to connect Manual Grabber to the device before playing with it; turn Manual

Grabber on and click the Bluetooth button at the top right corner of the screen, then wait until your screen says ‘Connected.’

• Students can click the ‘Performance/Connection Settings’ button at the bottom right corner to see if Manual Grabber’s parts are connected and working properly.

• Suggested advanced extension: Students can click on the ‘Set Light’ button at the bottom left corner of the screen to add lights to Manual Grabber.

Tips



- Helpful guiding questions for the Mabot GO control screen:

• What happens to Manual Grabber when you use the control pad on the left?• What happens to Manual Grabber when you move the lever at the bottom of the screen to a

different number?• What happens to Manual Grabber when you drag the 3 different bars on the right?

Coding

- Where you put the clockwise and anticlockwise values in the code will depend on which Drive Balls you put on which side of the robot. Run four test codes by changing the Drive Ball number each time in a Drive Ball code block. Run the code, whichever Drive Ball starts to move when it starts is the number in the code. Mark each Drive Ball with its number, using an eras-able marker, for easier identification throughout the activity.

- If you are programming the Rotating Joint in the Clipper and it is not moving, it is probably the wrong Rotating Joint being programmed as Manual Grabber has two. To fix this, change the number of the Rotating Joint in the code block to ‘2’ instead of ‘1’.

- If you want to separate code blocks, you need to drag the bottom code block(s) instead of the top.

- To start a new project on the Mabot IDE App and start programming Manual Grabber, follow these steps:

• Open the Mabot IDE App.• Turn Manual Grabber on and click on the Bluetooth button at the top right-hand corner of

the screen to connect Manual Grabber.• Wait until the yellow screen comes up to show that Manual Grabber is connected.• Once Manual Grabber is connected, Manual Grabber will make a noise and the ‘Detected

Device’ screen will appear.• Click on ‘Mabot.’• Click the tile with the plus sign on it to create a new project.

- If the transition from one code block to another in a program is not smooth, add a ‘Wait’ code block (usually 0.5 seconds will suffice) between them.
