Thames & Kosmos 620405 Remote-Control Robotics

Power up your playtime with a remote-control engineering adventure that’s charged by imagination! Build your own motorized vehicles and machines with up to three degrees of freedom, and control them with a powerful wireless remote-control unit. The unique, six-button Wi-Fi remote allows you to control three different motors simultaneously, moving each of them forward or in reverse at the touch of a button. 
The full-color, 80-page experiment manual guides the assembly of ten models that demonstrate the different ways in which the motors can be used and explores principles of mechanics such as gears, gear ratios, motors, torque, levers, pulleys, and more. Models include a car, antique car, formula one racer, crane, bulldozer, toy dispenser, one-robot band, beetle, droid, and robotic arm. After you’ve mastered these models, you can combine the durable, modular construction system and motors to design your own remote control creations! 

• Assemble 10 motorized models that showcase a range of robotic possibilities and demonstrate several principles of mechanical design
• 2.4 GHz Wi-Fi remote for superb remote control
• Over 200 durable plastic construction pieces allow young engineers to design, test, and redesign unique models from their own imagination
• Three independently controllable motors: two variable torque motors (26X and 90X) and a 50X motor built into the remote receiver
• Encourages hours of creative, open-ended play and develops fine motor and critical thinking skills
