As your mechanics and motor skills improve you’ll be able to move on to more challenging science projects. Finance is provided by PayPal Credit (a trading name of PayPal UK Ltd, Whittaker House, Whittaker Avenue, Richmond-Upon-Thames, Surrey, United Kingdom, TW9 1EH). Thanks to the transparent housing, you can peer into the kit and witness the intricate gears in motion, providing an engaging learning experience. There are two building levels to this little guy, level 1 for the amateurs and level 2 if you’re looking for something a little more challenging.No Batteries Required: With the solar-energy-focused design, these fascinating robots can move easily and provide great interaction with your child for days. Clear gear-housing adds to the educational value as children can observe the inner workings of the mechanics. You have the ability to control the robot's direction by simply changing the polarity, effectively reversing the direction of its motors. There should be about half an inch of metal shaft on either side of the white gear of the "gear with shaft" but the side that conects with C5 is slightly longer.
Then challenge yourself further with the Roly Poly Bot, AutoBot SlitherBot, SurfBot, BoxerBot, CrabBot and RowBot. Educational: Explore the world of electronics, mechanics, robotics, hydraulics or pneumatics with Velleman’s cool robot kits. Hone your child's interest in science, engineering, technology and ecology with the 14 in 1 Educational Solar Robot.The solar robot can become a tail-wagging dog, a walking crab, a surfer, a speedster and so much more! I didn't actually see what was in the box as they were bought as Christmas presents for my great-nephews who live many miles away. We found that sometimes the white gear on the "gear with shaft" can accidentally slide out of place and not allow for C5 to connect with the gear. These science activities help you practice fine motor skills as you build a robot car that runs on sunlight.
