Sillbird Solar Building Robot Kit 15-in-1 STEM Building Toy

Disappointed

Great project for my sons in team work but unfortunately it never worked once completed. We went over every step with no luck.

Great fun for the littlest engineer in your life!

I bought this kit for my 6 y/o nephew who is obsessed with robots ever since I introduced him to fighting robots through NHRL livestreams. I have no experience with robots or really any model building, and it was a great first kit for us. The instructions are clear and very easy to follow.

My nephew enjoyed using the snips to cut the pieces out of the grids; with supervision it’s a very easy task for a kid to do. Note that individual parts are not labeled with their numbers; they are numbered on the grid only. I was concerned we would have trouble identifying the 200+ parts once separated from the grids, but we kept the parts from each grid in ziplock baggies and wrote the grid letter on the bag. The images in the instruction manual are so clear that we had no trouble at all identifying the parts.

Pieces are modeled well and snap together securely. Be sure to clean up any snags from the grids with the snips or emery board, especially on all gear pieces. Even the tiniest bit of extra material can make the gears inoperable. The pieces also feel sturdy enough to disassemble and use again for multiple models. A few pieces may need a slim piece of metal to pry them apart—definitely a job for older kids or adults.

My only complaint is the contacts from the wires to the battery. They are very loosely fit so it loses power a little too easily. An on/off switch would be a more durable solution, but for the price this is a really minor issue. My nephew was able to slide the contacts into the slots with a little practice; they just move/lose contact with the battery a little too easy.

It took us about 1hr to snip all the bits out of the grids, another 30 min to clean up the snags, and 45 min-1hr to assemble Robot 1.0. We can’t wait to try more of them over the summer!

My son loves this!

This is great for the kid that loves to put things together and loves technology! Also this is a great bonding tool to do with someone else! Lots of pieces and opportunities to make different things while learning science. Just the fact that it can be powered by the sun is just awesome and you can make 15 different robots. It's got 212 easy build pieces! It's got easy detailed instructions. My son cannot wait to build this and it's also awesome that he's interested in something other than screens.

Another good STEM 15-in-1 solar and battery powered robot toy for 8+ years old

I got these robotic toy kits for two kids 6 and 8 years old. I have gotten a few robotic toy kits before, as the toy allows the kids to gain hands-on experience in assembling things and learn some basic concepts of science and engineering with adults' help. In this case, dual energy source from solar energy, and stored chemical energy from battery converted into mechanical energy to power the robot toy. Also the kids learn how gears and wheels work. The toy is a 12 in 1 set, and 12 different robots can be built, except disassembling is needed going from one to another (a negative). The kids will be awarded with a finished toy that they can play with. I do not expect the kids to complete all 12 versions as it will take a long time and disassembling one to go to another may break some parts. It would be good if they could try out a few interesting ones.

I do not expect kids to fully assemble them on their own. Usually, I got them and guided them and figured out the steps along the way. Taught them some things about mechanical and electrical concepts during the assembly to grow their interest and knowledge. It is not a one time thing and hopefully after a few toy assemblies, the kids will understand the concept, and how to assemble things better and better,

Model type parts for different robots

If you’ve ever done a model car or a model airplane or a model ship, the parts are plastic and come on a frame. That’s what this robot is. It will be hours of fun. The instructions are very easy to follow. And they have different types of robots that can be set up. The motor is very small so it’s not going to go very fast.

Complicated!

I got this as a gift for a ten-year-old who is very interested in science and building, so all I've done is open the box and look at the bagged pieces. To be honest, it looks very complicated, and if he wasn't so invested in all things science, I might give it to someone else. I think Ages 8+ is a bit optimistic--younger or easily frustrated kids will most certainly need help. The instructions say a "diagonal or spruce cutter" (I have no idea what that is) and a nail file or emery board might be needed. The emery board is included. The 212 pieces must be detached from plastic holders, then sanded smooth on the edges. On the positive side, this isn't a toy that will be discarded after 30 minutes of play. It'll probably take that long to get the pieces loose. Another plus is that though the robots are solar powered, they can switch to being battery powered. Don’t miss the fun fact about prehistoric solar panels on the side of the box! Because of the scope of the toy, it seems reasonably priced. I based my rating on the assumption that the toy ends up in the hands of a patient, science-loving child who can count on help if needed.

Very complicated solar robot building toy, great for 12 and up or younger with adult help

This is a great STEM toy that lets you build 15 different working solar robots. The kit arrived pristine, packed in a a secondary box, unlike another kit I ordered that arrived crushed. Great for gift-giving! This is a very complicated building toy with many small parts. Unless your child is already experienced and adept with assembling complicated build and small parts, I think the age of 8 is probably too young unless there is a patient adult working with them to help out. For independent use, I think 12 to adult is a more realistic age range. I would also be careful using around very young siblings or pets, and the parts are quite small and can be a choking/ingestion hazard. You will likely want to have a pair of wire cutters and a file on hand to help remove plastic parts from the frames and smooth edges when needed. This is a great next step for kids who already enjoy things like complex Lego build toys. I think this kit is a fantastic gift idea to provide many hours of summer activity, while also opening your child’s eyes to how their love of building things can translate to science, invention, and possibly a career. I love that it is solar powered and introduces principles of electronics, engineering movement, and solar energy to kids/teens. I also love that they can build 15 different robots and re-use the solar panel in each, so that the kit continues to offer multiple projects rather than just one finished piece that sits there forever. I have included photos of some of the instructions so you can get a sense of the complexity of this robot building kit. Not for the faint-hearted, but I think this kit can be a potentially life-changing toy for the right kid or teen. I would personally only recommend this toy for kids (or adults!) who already enjoy and are adept at building things using many small parts, such as big Lego kits. This is the logical next step from building for example the Millennium Falcon, to building actual working robot “droids” that look like you might see them in one of the movies of that series. Super fun gift and perfect for older kids and teens with many hours to fill over the summer or winter breaks.
