Snap Circuits Elenco Teach Tech Mech-5 | Programmable Mechanical Robot Coding Kit | STEM Educational Toys for Kids 10+

It's a wonderful scientific robot for 10+ boys who love building and coding. They need to have patience and curiosity about building a scientific project and see the result. Instructions are clear but a child will require adult supervision. The parts are clearly numbered but we found that we had to make sure all the burrs had to be completely removed and sometimes filed down after the pieces had been cut from the frame they came on.The first time we built the robot the cog mechanism was cluncky and the cute robot did not operate correctly. But reassembling and making sure the burs were filed , the cogs worked smoothly. It became a family project. We liked the fact the mechanicalstem coding robot used coding buttons ratherthan digital techology. Designed to inspire users to learn about mechanical engineering and coding basics This made it more accessable for our son (10) and he could "programme" the robot to do his own tasks. Really well designed educational product. We found one of the wheel axels was cracked and the wheel came off after a few .seconds. This may have happened in manufacturing or when we cut the wheel from its frame.Well worth the money.
