## 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!

Review: HOURS OF FUN - This great to learn about hydraulics and I consider it better than other items you have to assemble like legos, etc. because of the educational value. It is fully functional and provides hours of entertainment and although it was purchased for my grandson, I also am enjoying playing with it with my grandson. The instructions are very clear and the parts are well built, especially for the 'roughness' of a 10 year old assembling it. There is lots of value to this item and it is much more than a mere toy!
Review: Fun and educational - Complicated build but oh so worth it. Quality is good and you actually learn something. This toy is an absolute blast, and my 10 year old loves it!

### ⭐⭐⭐⭐⭐ Grandson loved it
*by S***C on January 3, 2026*

Purchased this for my 8 year old grandson who is great at building Legos . After purchasing this, I realized that it was probably too advanced for him, but with the help of his father, was able to build about 80% off this by himself. A lot of the work had to do with separating the little pieces before assembling. Once completed though, he loved operating the boxing robots with his brother. It is surprisingly sturdy.
