Distance sensor: allows a robot to measure distance using ultrasonic waves. Gyro sensor: allows a robot to measure turn rate and angles. similar to a bumper switch but with a flexible lever arm triggering the switch. It Limit switch: allows for more flexible mounting options than the bumper switch. Potentiometer: allows a to determine the position and direction of rotation of a shaft. Prototype: an early model of a product built to test a product or process. Reflective object sensor: similar to a colour sensor, but includes a light source and detects the presence or absence of a reflective object at very short range (typically < 5 mm). An arrangement of two or more reflective object sensors can form a line tracker. Robot controller: the brain of a robot that can be programmed using software. A robot controller sends instructions to the components of a robot and receives input from sensors. Estimated Time Approximately 4 30–60 minutes for the design thinking process 30–60 minutes to redesign/customize/build a robot that is tailored to the proposed solution 2 hours to test the prototype and repeat the design process until an adequate solution is found Recommended Number of Students 20–25 students Facilities A computer lab with programming software or reasonable equivalent is required to complete this activity. It is also recommended that tables be arranged in pods so that groups of students can work together during the design thinking process. Tools Ideally there should be an assortment of standard classroom supplies that will aid the students in their problem solving.
