## Description

In this corner, hailing from the rough-and-tumble robotics lab: It’s Robo-Boxer! And in that corner, the wonder from Down Under: Put your mitts together for Kangaroo-Bot! Ding! Ding! Jab, dodge, uppercut! These boxing robots use hydraulic power to move like real boxers. Packed with the excitement of a boxing match and the fun of constructing incredible mechanical models, this kit allows you to build two boxing robots and challenge a friend to a match. With complex shoulder gestures, two boxing punches (jab and uppercut), three waist postures, and interchangeable heads, these robots are designed to float like butterflies and sting like bees. Use the handheld hydraulic controls to fight like a champ. Knock your opponent robot’s head backward and score a point on the included scoreboard. Learn about how these amazing machines and hydraulic systems work. Leave the rocking and socking to the lightweights — this awesome STEM kit really packs a punch!

### ⭐⭐⭐⭐⭐ Must have for young builders too! Unbelievable value.
*by N***P on 12 October 2024*

I purchased this kit for my 6yo son and I to work on, we have never done a modeling kit like this before and our prior experience is with legos. My son loves to build and he loves robots so I thought this kit would be a good transition to something other than legos. I knew going in it was going to take a long time and I set that expectation upfront. We would spend 30minutes to an hour once a week on it until we finished. I realized quickly I would have to do the cutting if I wanted the pieces to have clean cuts, I used an old pair of cuticle cutters that did just that, no sanding required (that’s what I had and worked for us) and my son did the building. He completed 80-90% of the build on his own and I provided guidance the other 10-20% and as recommended in the instructions, we recruited his 9yo sister to build the 2nd robot so we could finish faster. After the 1st building session my son asked everyday if we could work on the robot, he loved this project so much he couldn’t wait for me so he started to build and cut pieces on his own until he got stuck and he would ask for help. We love the side to side hip action, ability to change from upper cuts to jabs, interchangeable masks, kangaroo and robot. My son did ask if I could purchase additional masks for more variety of boxers, so maybe this could be considered as a future product add on. This kit is absolutely amazing and an astounding value at $35, we definitely recommend it to kids that love to build, the quality of the pieces, the experiment for hydraulic vs pneumatic power, and at the end of it all you have two water powered boxing robots that you built!! So cool!! This is the best toy I have bought in a while. I will look into purchasing more items like this, it is so much more than a toy. Thank you Thames and Kosmos.
