The ROBOTIS Dream II Level 3 advances from the Easy Entry Level Robotics kits (Levels 1 &2) to go beyond teaching basic robotics.
You will need to purchase ROBOTIS DREAM Level 1 & 2 to build the example robots in Level 3 or the jump kit + Level 2 sold separately.
Level 3 expands from Levels 1 & 2 and uses sensors such as IR, speed, and sound to move and detect.
Level 3 builds upon Level 2 to develop a higher level of understanding or robotic principles such as the principles of speed, elasticity, inertia, acceleration, and resultant force.
Comes with 12 chapters and 12 example robots, with instructions on assembly, applications of scientific principles and problem solving and remote controller.
Once you are done with Level 3 you can move on to ROBOTIS DREAM Level 4 expansion kit.
