The main parts of a robot are three. Sensing part, Brain part, Acting part. There are different types of sensors in the sensing part. For example: IR sensor array in case of line follower. Sonar, IR Obstacle or IR Proximity Sensor for Obstacle Avoiding Robots Sensors are essential for any measurement project.
Ruku was introduced to TechShop while searching for a temperature sensor. He chose the simplest of the many temperature sensors. Starting from that. Then Ruku and his friends chose censors at different times from TechShop for different academic and non-academic projects.
Fingerprint sensor for attendance systems, RFID tags; PIR sensors, LDRs, thermistors, gas sensors, water level sensors for home security and automation projects; For robotics are effects sensors, current sensors, flex sensors ;Gyro, compass, accelerometer for quadcopters --- Oops!The names of the sensors cannot be finished. Do these only come in handy for engineering students?With heart rate sensor, IR thermometer, GSR sensor, oximeter, blood pressure sensor, muscle sensor, load sensor, etc., all the much needed medical devices are being made.
The website has links to tutorials or small sample codes for the use of almost all the sensors in TechShop. Ruku and his friends had no problem using the sensors.
