Some of the most popular robotic kits are also the friendliest towards the environment. Current solar technology has allowed kit designers to include solar panels to replace batteries that would eventually end up in landfills. Solar-powered robots can range from simple to complex, and they can be an excellent way for beginners to learn exactly how this alternative energy source works. Attaching and charging a robot’s solar panel is a perfect hands-on way for builders of all ages to explore the applications of this clean-energy technology.
Solar power refers to the conversion of sunlight into electricity by a direct process called the photovoltaic effect. This technology relies on a semiconductor to pull radiation from the sun’s rays and convert it into a direct electrical current. Another type is known as concentrated solar power, which relies on a system of reflective lenses or mirrors to generate an indirect electrical current when exposed to strong sunlight.
The direct method with photovoltaics is used for both large and small-scale solar panels made with a specific number of solar cells. Some of the first devices to use this technology were single-cell solar-powered calculators. The modern solar robot is powered with the same basic technology, though sometimes with more than one cell.
A robot kit’s motor works with a direct electrical current that comes from at least one charged solar cell. Depending on the complexity and difficulty level of a robot kit, the builder will need to attach each of the cells to the robot either by epoxy gluing or by soldering for more advanced kits. Solar robot cells act as receptacles for sunlight, and different robot motors require solar cells that can be charged to a certain voltage. The needed number of volts typically depends on the size of the robot, its number of moving parts and the electric power required to fuel them. Many robot kit solar cells attach to the motor with simple wires by soldering or with locking connectors found in some beginning level kits.
A number of OWI’s most popular solar robot kits provide young builders a challenging but fun project that teaches some fundamentals of science and engineering. Assembling an environmentally friendly robot will demonstrate the benefits and possibilities of solar power as an emissions-free power source. For beginning to intermediate robot kit enthusiasts, some favorites include:
6-in-1 Educational Solar Kit. This robot kit is designed for beginners and does not require seperate tools to attach the parts together. Options include building a small solar-powered windmill or one of two toy airplanes.
7-in-1 Rechargeable Solar Transformers. Robot builders can put together several different toy vehicles with this beginner-friendly kit. One big selling point is its high-caliber solar cell that recharges to full power in only minutes.
The Solar System was featured in Educational Dealer Magazine as “one of the items most ordered at the NSSEA show…Great New Products from Ed Expo.”
Solar robot kits are a fun, educational and creative means of learning about this type of energy-efficient technology. Here’s a video of OWI’s products featured on The Late Show with David Letterman. Note for impatient souls: skip to 1 minute into the video.
