9-in-1 Science educational robot DIY kit | SR-160509
The 9 in 1 Science Kit is an educational robot DIY kit which can simultaneously build at least 9 classic STEAM application cases.
Each structure is cleverly designed, simple and compact, and is closely integrated with the school’s internal science and physics
classes to stimulate students’ scientific interest.
Crank and Rocker Mechanis
The crank is master drive and moving at the same speed, while the rocker is slave drive, moving back and forth at variable speed, and the connecting rod is making compound motion in one plane.
Double Rocker Mechanism
Both rockers can be used as master drive members. When the master rocker swings back and forth, the driven rocker swings back and forth through the connecting rod.
Slider-Crank Mechanism
The crank and the slider mechanism is one planar linkage mechanism that can transfer the movements between rotation and sliding.
Meshing Belt Driving Mechanism
Keep the belt drive synchronized, utilizing the gears’ gear ratio difference, it can reduce the speed and increase the torque.
Oscillating and Reciprocating Mechanism
With the combination of the slider crank mechanism and the gear-linkage transmission mechanism, the rotary motion is converted into a reciprocating swing motion.
Generator
The gear transmission mechanism drives the motor rotate and reversely cut the magnetic induction wire, and therefore generate electricity and light up the led, realizing the process of energy conversion from Electric energy to mechanical energy to electric energy.
Ultrasonic Guitar
Utilizing the ultrasonic sensor ranging function, the preset sound will be played depends on the detected distance of the slider, the color of the RGB led will change accompanying the ultrasonic.
Ultrasonic Radar
Ultrasonic radar uses one motor to rotate the ultrasonic sensor in 360 degrees horizontal, if measured object in its detection range, buzzer will make response and ultrasonic sensor would be moved up and down by the second motor.
Music Robot
Utilizing the line-following sensor as the limit switch; the gear drives the gear rack back to the initial position; then rotate reversely to drive the gear rack to move and start playing music; when the music playing is done, the gear rack returns to the initial position; and repeats the above motion.
Clean Demostration
Easy to assemble, rich forms with clean appearance, a good choice for demostration in
maker space, show room. 
Easy to Program
Write a program by simply dragging
and dropping with WeeeCode software.
Learn a language to communicate with
robot.
