How Do Sensors Work? - Curricular Unit. Curricular Unit: How Do Sensors Work? Through six lesson/activity sets, students learn about the functioning of sensors, both human and robotic. In the activities, student groups use LEGO® MINDSTORMS® NXT robots and components to study human senses (sight, hearing, smell, taste, touch) in more detail than in previous units in the series.
They also learn about the human made rotation, touch, sound, light and ultrasonic sensors. "Stimulus-sensor-coordinator-effector-response" pathways are used to describe the processes as well as similarities between human/animal and robotic equivalent sensory systems. The important concept of sensors converting/transducing signals is emphasized. Through assorted engineering design challenges, students program the LEGO robots to respond to input from various LEGO sensors. The overall framework reinforces the theme of the human body as a system with sensors—that is, from an engineering perspective. Our Bodies Have Computers and Sensors - Curricular Unit. Curricular Unit: Our Bodies Have Computers and Sensors Students learn about the human body's system components, specifically its sensory systems, nervous system and brain, while comparing them to robot system components, such as sensors and computers. The unit's life sciences-to-engineering comparison is accomplished through three lessons and five activities.
The important framework of "stimulus-sensor-coordinator-effector-response" is introduced to show how it improves our understanding the cause-effect relationships of both systems. This framework reinforces the theme of the human body as a system from the perspective of an engineer. This unit is the second of a series, intended to follow the Humans Are Like Robots unit. What Is a Computer Program? - Curricular Unit. Curricular Unit: What Is a Computer Program? Through four lesson and four activities, students are introduced to the logic behind programming. Starting with very basic commands, they develop programming skills while they create and test programs using LEGO® MINDSTORMS® NXT robots.
Students apply new programming tools—move blocks, wait blocks, loops and switches—in order to better navigate robots through mazes. Through programming challenges, they become familiar with the steps of the engineering design process. The unit is designed to be motivational for student learning, so they view programming as a fun activity. This unit is the third in a series. PowerPoint® presentations, quizzes and worksheets are provided throughout the unit. Riaz Helfer, Sachin Nair, Pranit Samarth, Satish S. Robot Design Challenges - Curricular Unit. Curricular Unit: Robot Design Challenges Through the two lessons and five activities in this unit, students' knowledge of sensors and motors is integrated with programming logic as they perform complex tasks using LEGO® MINDSTORMS® NXT robots and software.
First, students are introduced to the discipline of engineering and "design" in general terms. Then in five challenge activities, student teams program LEGO robots to travel a maze, go as fast/slow as possible, push another robot, follow a line, and play soccer with other robots. This fifth unit in the series builds on the previous units and reinforces the theme of the human body as a system with sensors performing useful functions, not unlike robots. Sachin Nair, Riaz Helfer, Pranit Samarth, Satish S. Humans Are Like Robots - Curricular Unit. Curricular Unit: Humans Are Like Robots Four lessons related to robots and people present students with life sciences concepts related to the human body (including brain, nervous systems and muscles), introduced through engineering devices and subjects (including computers, actuators, electricity and sensors), via hands-on LEGO® robot activities.
Students learn what a robot is and how it works, and then the similarities and differences between humans and robots. For instance, in lesson 3 and its activity, the human parts involved in moving and walking are compared with the corresponding robot components so students see various engineering concepts at work in the functioning of the human body.
This helps them to see the human body as a system, that is, from the perspective of an engineer. Students learn how movement results from 1) decision making, such as deciding to walk and move, and 2) implementation by conveying decisions to muscles (human) or motors (robot).

The robot will be able to follow a line which makes corners sharper than 90 degrees using a proportional line follower.
(For more resources related to this topic, see here.) First, you will need to build an attachment to hold the color sensor onto the robot. Insert an axle that is five modules long into the color sensor. Attach the two-pin one-axle cross blocks onto the axle outside the bushings. Insert 3-module pins into the cross blocks as shown in the following figure: The pins will attach to the robot just in front of the castor.

Some of the many uses of strawberry baskets: structural support for scribbling machines! An offset weight on a motor, a power source, a supporting structure, and a writing implement: the prototypical scribbling machine. Troubleshooting a top-heavy contraption. A clever switch to turn the contraption on and off! Typically, we arrange participants around a communal table to encourage sharing of ideas.
Facilitation is crucial: both with Tinkering Studio staff, and between parents and children. Even very young tinkerers can be successful if properly supported. When doing this activity outdoors, we have experimented with chalk instead of markers! And, since the sun is a plentiful resource, why not add solar panels instead of batteries? Tiny modifications lead to big changes in behavior, and it takes observational skills to troubleshoot. Chalk Scribbling Machines was a big hit at Maker Faire 2013! Going against the grain: why not make an erasing machine? Hummingbird Robotics Kit.
BrushBot Kit. SunBEAM Seeker Bot. BEAM robotics is a way of thinking about and building robots with roots in the “behaviorist” or “actionist” robotics movement of the 1980s. Rather than relying on microprocessors, programming, and digital logic, BEAM designs favor discrete components, stimulus-response control systems, and analog logic. From a design perspective, BEAM robotics is about getting the most complex and interesting behaviors using the simplest circuits, actuators, and components. Therein lies the challenge. BEAM is an acronym for: Biology — BEAM robots take inspiration from nature, especially “simple” organisms like plants, worms, and insects.
The SunBEAM Seeker is a very simple phototrope (meaning it responds to light) based on Randy Sargent’s classic “Herbie” design, which he originally developed for a line-following competition at the Seattle Robotics Society’s 1996 “Robothon” event. We published a more complex version of the Herbie design as Mousey the Junkbot back in MAKE Volume 02.
How It Works. My Robot, Makey. Step #1: Make the body. PrevNext The body consists of 2 pieces of sheet aluminum. You can cut, drill, and bend one piece at a time, or do both at once to minimize switching tool stations; see Step 5.Download the 5 Makey templates from and print them out full-size. Cut out the base cutting template, and cut holes in the blank area of each panel. Securely tape the template to the aluminum sheet with double-stick tape on the back and regular tape over the holes.CAUTION: Always wear protective eyewear when cutting metal.With a band saw, cut the aluminum roughly to size around the template, then cut the perimeter just outside the lines.TIP: For inside corners, first cut a gradual curve close to the corner, then back up and cut into the corner’s point from each direction.
Step #5: For the body’s top cover, repeat Steps 1-4 using the top cutting and bending templates.Now you’ve got one sweet chassis any robot would be proud to wear! Step #6: Add the drivetrain.
