Product Description

Build, code, and play — with mighty REX! Assemble your own robotic model of the giant, powerful, ferocious Tyrannosaurus rex. Use the handheld controller to command your robot to move around in all directions, light up its eyes, and play sounds, including chowing down on food and even farting! The special Code+Control wireless unit enables you to either directly control REX in real time, or write and save sequences of commands for the robot to perform at the push of a button. No app or separate devices are required! REX makes hands-on STEM learning fun and accessible. First, follow the step-by-step instructions to assemble the robot and controller from 100 pieces and decorate your completed dino with stickers. At 11 inches tall and 19 inches long, REX really commands respect! Then, learn the function of each button on the controller and how to combine those functions together into programs for your robot. With two motors and a flexible tail, REX can move in one of two ways: walking or gliding. Put REX into guardian mode and it will use its infrared sensors to identify intruders then unleash a ferocious roar! The process of assembling REX gives you an insider's look at various electrical components found inside many robots and by experimenting with the different commands your robot pal can follow, you'll get a clearer understanding of how robots work!

    Fun, collaborative building set that challenged our 9 and 6 year olds
    Our kids really enjoyed building this T-Rex. Our 9 year old twins and 6 year old daughter were able to work together to build it (mostly) without our help. They've had a ton of fun with it after it was built as well. This kit is a great option for kids who are looking for something a bit more advanced than traditional brick sets.

    Kids really enjoyed this. Takes couple hour to assemble as adult so prepare for that. Instructions are easy to follow. Control has lots of options to explore. The finished product does not move very quickly but can be maneuvered around, under, through and in reverse too. The kids enjoy the noises (soft farting sound) to add. Recommend as fun gift. Good value for the cost and interest.

    After putting together a few toys and robots for my kids, I’m always nervous about putting one together.
    But this one had great instructions and it took me about 30 minutes total. I put it together without my kid because they’re quite young but I think a kid 7 years or older could handle it.
    It requires 5 AA batteries.
    It has so many modes, doesn’t require you to code to make it run, but it also has a coding mode where you can instruct it to do a set of tasks.
    My kids were also delighted that it had a “fart” button, lol.
    Overall, a great quality robot and brings plenty of fun and learning about coding.

     I bought this for my 6 year old son. He and I had fun building it together. He mostly just needed help making sure the wiring was ok (it’s simple and has easy to follow instructions throughout). It works well and he loves using it to battle his other remote control toys, so it’s sturdy! Great toy overall, no complaints so far!

    This is a work in progress. I can say it's very nicely made and all the pieces were there. I'm having fun with my grandson when he comes. We've got it partially together and i cant wait till we get it completed. We work on it when he stays over with me. Quality time alone is worth the price. Would make a great gift.

    Got this for my 7y we built it together. I had to help him with the building instructions as some parts where hard for him to understand how it went together. Only problem he has was snapping the pieces together but his finger strength is a problem for him. Once built he loves playing with it ! He loves chasing people and making it fart.

    Only problem is it can be front heavy and fall forward sometimes

    Overall happy we got it
