CONSTRUCT & CREATE Wabo The Robot Gyro Monorail Science Kit - Battery Powered DIY STEM Toy

Kids really like this both fun and interesting stuff, but assembly needs expert adult skills!

Does what it says on the box, easy to build and assemble the track.

Not easy to build but great fun. It needs patience but the instruction is easy to follow anyway.The end product, I mean once all set up, is fantastic, a working robot like a toddler, lovely and cute, every time you think it may fall but alas, no, just keep going safely.The whole process is entertaining and educational, a lot effort and full engagement, and the achievement is great satisfaction. Would love to recommend it, highly,

The media could not be loaded. The construction of the Robot Gyro Monorail Science Kit was a pleasure but it is not a five minute job, and essentially until it is built consider it as a model building kit. The manual or book of words is well put together and easy to follow.All the plastic parts (95% of the model) are held within injection moulding frames of which there are six and designated as A to E. 130 parts in all. In addition there are 8 ball bearings (the heart of the gyroscope) gears, electrical motor, spindles. Also included is a sachet of oil.All the parts fit together well, and screws are used to ensure a tight fit between parts when it is needed (30 screws). The result is a solid construction.The various parts should only be cut out when needed so parts do not get mixed up. Patience is needed in liberating the monorail parts (52 parts in all). To ensure a proper fit the ends of the monorail sections should be filed to ensure the complete removal of the burs.The end result of the construction is a working robot traveling along the monorail. The points or splitters work well so the layout need not be one monotonous oval.When starting the robot, let it run for ten or more seconds to get up to speed before putting it in the rail. Also note that when switching it off, it will run on for about twenty seconds due to the kinetic energy stored in the gyroscope.SummaryIt is nice to see a model you construct where all the parts fit together easily A solid robot and monorail tract. A real educational toy. The end result is very pleasing.Notes on constructionThe are some prerequisites as follows:two AA batteries;a small Philips screwdriver;a small pair of diagonal side cutters (‘diags’);paper towel (described as tissue in the book of words). The paper towel is to safeguard the surface where the robot is assembled. In building the robot the oil is used to lubricate the gears prior to the gears being enclosed in their casing, and the paper is to prevent any drip from spoiling the working surface.Another useful tool is a mini file.The diags are used to clip out the plastic parts and then to remove any burs which are left. The file is used to complete the removal of the burs.The first to parts to remove are E3 (the oil reservoir) and D9 the oil applicator. Once the gears have been lubricated the oil reservoir and applicator are redundant.There are four modules to make;The robot;Two sets of points or splitters;The Cross Switch;The Seesaw.In addition to the oil reservoir, an applicator, there is another plastic piece, which is only used as a tool, and that is D1 (of which there are two copies) that is used to bed down the battery contacts. Further D1 is used to embed the supply wires into the sides slots. Both D1s are used as temporary positioning posts for the gears in the cross switch assembly. After that they are redundant.In seeking to remove the burs be careful with part E4 used in the 3-way splitter. It has a pointer which could be easily mistaken as a bur.Once the modules have been completed and the monorail track parts have been assembled you are ready to run.
