Description

Build your own adorable robotic pet Hedgehog! With the 172 building pieces in this kit, you can assemble a real robot that looks like a cute Hedgehog. The robot has a built-in sound sensor and is programmed to react to different sounds. After you build it, you can play with it by making different sounds and watching it tumble, roll, spin around, Bristle its spines, and scurry around. Clap once, and the Hedgehog will roll into a ball and tumble backwards. Clap multiple times, and the Hedgehog will count your claps and tumble as many times as you instructed with your claps. You can also get the Hedgehog to Bristle its spines and act in a playful way with different patterns of claps. The Hedgehog eyes light up with LEDs. By building the robot, you will gain experience in the inner mechanical workings that enable the robot to move how it does. Learn about gears, motors, sound sensors, LEDs, and the other components of these funny little pet. Approximate build time: 1 to 2 hours. Difficulty level: challenging.

Frequently asked questions

The Thames & Kosmos Tumbling Hedgehog is suitable for kids aged 7 and up. It's designed to be an educational toy that introduces young learners to basic engineering and robotics concepts, making it perfect for this age range.

No, you do not need to buy any extra parts or tools. The Thames & Kosmos Tumbling Hedgehog comes with all the necessary components for assembly. However, you may need to have screwdrivers and batteries handy, as these are often required for assembly but not included in the kit.

The sound activation feature on the Tumbling Hedgehog allows it to respond to different sound cues, such as claps or shouts. Once it hears a sound, the Hedgehog will begin to tumble, roll, or scurry around. This feature is a great way to engage kids in learning about sound sensors and basic robotics.

While the Tumbling Hedgehog does have pre-set behaviors related to its sound activation feature, it does not support custom programming or behavior modification. The main educational value lies in the hands-on experience of building and understanding how its mechanisms work in response to sound stimuli.

🚀 Abunda's Overview

This is our summary and key points to consider based on customer reviews.


The Hedgehog Rolling Robot is a complex and engineering-focused toy that requires significant assembly time, often deemed too complicated for younger children without adult help. While some have found the assembly process and the toy's functionality enjoyable and educational, others report durability issues and challenges with the toy responding to controls as expected. This toy seems to best suit older children or adults with a keen interest in engineering and assembly, offering a mixture of creativity, problem-solving, and hands-on building experience.

Pros

  • 🔧 Offers a creative and engaging STEM learning experience
  • 👪 Encourages collaboration between children and adults
  • ✨ Parts replacement and customer service are prompt and efficient
  • 🎁 Brings joy and a sense of accomplishment once assembled

Cons

  • ❗Highly complex assembly not suitable for younger children without adult assistance
  • 🛠️ Durability issues with parts breaking easily or not fitting properly
  • 🔇 Sometimes fails to respond to clap commands as expected
  • 😞 Some find the assembly process tedious and not worth the effort

Should I Buy It?

If you are looking for a challenging and engaging STEM project that offers hands-on building and problem-solving opportunities, and you have the patience for a complex assembly, this could be a rewarding purchase. However, if you are seeking a toy with immediate playability out of the box, or are purchasing for younger children hoping for an independent building experience, you might want to consider other options.


  • Customer Service is spectacular
Style: Hedgehog Rolling Robot
Came missing parts so my son sent me the ones needed and the company sent them pronto. All was a relief as you cannot put it together without the parts. It is not really for younger children unless an enthusiastic adult helps. It is a bit complicated.

  • Hard to determine cause of problems
Style: Hedgehog Rolling Robot
All parts must be snipped out of a plastic frame. There is one early point where you connect the battery and control module to test the gears. There is no further test until you are done. When you are done and the gears make a strange noise it is difficult to take apart to fix. I still do not know why mine does not work after taking it apart many times. There was also one bracing rod that did not seem to fit without cutting and glueing. This definitely has nothing to do with my problem. I would like to see more explanation about the design and how everything works with just a forward and reverse of the motor. It may help to determine what would cause certain problems. REVISED: I finally got it to work. It needs a smooth floor and will flip on its side on a rug. I think it just took a while for the gears to turn smoothly. ... show more

  • Nephew LOVED it.
Style: Hedgehog Rolling Robot
We gave this to our Nephew in 2020, and I went over to his home this week and he brought it out and showed me all the things it can do. It has lasted over a year of playing with weekly. He let me know it was a fun gift as he was able to work with dad and build in a new way and do some coding. Great job! Great Value, and his smile was priceless. ... show more

  • Assembling something doesn't mean learning robotics. Also, it BREAKS.
Style: Hedgehog Rolling Robot
This was a last-minute purchase for Christmas and I foolishly ignored the reviews saying it was hard to assemble because I figured I would "help" my son. Please see & heed all reviews about what a PITA this is to assemble. It's not "challenging" or a learning experience. It's BUSY WORK. Yes I was able to do it. Yes the instructions are clear enough -- for a adult. Kudos to the tech writers. But will a kid learn how the mechanics actually function or be able to experiment with differing gear arrangements? No. This is, once built, done. And once it's built, parts fall out (we especially the two big metal cylinders in the head which don't snap into place) making it dangerous, and most importantly: The thing doesn't really respond to the claps as stated. If you want a robot toy that responds to noise commands, but one pre-made -- THIS IS NOT IT. If you want a project that kids can do that will teach about mechanics and offer the opportunity to use imagination and problem-solving, THIS IS NOT IT either. Honestly, find an old toy and take it apart rather than buying this. UPDATE: Even after assembly, he hedgehog falls apart. Parts don't snap into place -- they are lose and fall out. Currently, without one tiny pin, a leg is lost. A plastic strip that stretches when the hedgehog curls up has snapped. This is from one day of regular use. And It NEVER flipped over. It is assembled 100% correctly. If anyone reading reading this just thinks those of us who struggled with it are dumb or have dumb kids, check yourself please. The thing is poor quality. ... show more

  • any child should be able to put this together
Style: Hedgehog Rolling Robot
my son 9 years old received it at 6pm on 3-31-20. it is put together in less than 2 hours. he loved the challenge of the build. i ( his father) did not help him build it. he did that on his own. instructions are easy to read, and simple to put together. " this takes attention to detail and patience/focus" I was looking for something for my child to do while home from the pandemic. note: the first package they sent the battery pack was damaged. they sent a new product out in days. thank you for your fast response. ... show more

  • Got one day of play
Style: Hedgehog Rolling Robot
So this was extremely complicated to put together theres no way an elementary aged child is putting this together with any level of independence. It worked great for less than 24 hours and now is broken and won't work. My son is now devastated since this was his gift from Santa and it took a month of weekends to assemble. ... show more

  • Nice toy but breaks easy
Style: Hedgehog Rolling Robot
Bought as a gift for my daughter, she was so excited. After spending over an hour to build it, she finally got to play with it. Not the easiest control, you clap to make it work. After the first day the peg that holds the gear that drives the wheels broke. Now I spent a hour trying to find a way to fix it then the button that turns it on and off isn't working right. Daughter isn't happy with it anymore because it keeps breaking. If it would work without breaking it would be a great toy but as is, it is only ok. ... show more
