Description

Have a blast with this awesome engineering project! Construct an air-powered robotic glove that launches safe foam darts. Learn about pneumatics — technologies that use pressurized air to perform work — and many cool mechanisms as you assemble the blaster from over 100 pieces. After you’ve built and tested your blaster, slide it on and strap it to your wrist. The first pull of the trigger causes the scissor arm to lift up the barrels and launch the first dart. Pull the trigger two more times to launch the next two darts. Grab some additional darts from the reserve clip under your wrist and reload. The blaster is entirely powered by your hand and the amazing pneumatic system — no batteries or motors required! Turn the dial to rotate the two outer launchers for a wider spread. Adjust the location of the wrist strap to fit almost all hands. A full-color, step-by-step manual guides you through assembling and using the blaster and provides fascinating scientific information about pneumatic systems and the physics of air. Compatible with many standard foam darts.

    • Claw hand
Fun toy for young boys. Fits on the hand and shoots out Styrofoam bullets. Made well with easy assembly.

    • Extremely Frustrating
I've built several Thames and Kosmos kits with my kids - including the really complicated hydraulic hand. The other kits were great, so I bought this one cause it looks really fun.... But, it's horrible. First, you need a very small screwdriver and a pair of wire cutters that are not included. No big deal there. The problem is the build is EXTREMELY frustrating and it's VERY FLIMSY. The whole top part of this that hold the bullets doesn't secure on in any meaningful way and it comes off easily. The little sights fall off easily. The spring that is supposed to help raise and lower the launcher part is not only difficult to put on, it unhooks constantly. I took this thing apart and reassembled it several times. I must have spent a minimum of 3 hours just trying to "fix" this. I'm the end, I can't get it to work as intended. The handle jams up and won't compress, gets stuck in place, or does not generate enough force to compress the springs in the back because the gears get caught up. One half of the handle slides up more than the other and then it gets stuck. I poured oil I had on this over liberally over every single gear, contact surface, and spring trying to get this to function. It'll launch a bullet if I manually pull the air generator apparatus back, which is tricky to do, but I know that part works. It's the handle and gears of this thing... Which is also really annoying because the handles have multiple tiny screws in them add its a total pain to have to deconstruct them again and again. I did not enjoy this. The fragile construction and unfuncrional results are disappointing and just frustrating. Frustrating.... And I feel Iike I should type that about 5 more times. ... show more

    • High tech adventure
The Thames & Kosmos Ultimate Bionic Blaster, aka the Robotic Hand, is the closest thing my nephew has to becoming a superhero without the need for radioactive spider bites. He put it together faster than I can untangle Christmas lights – a true Christmas miracle! Now, he struts around like he's part cyborg, high-fiving and grabbing things with the precision of a bionic ninja. If only I could convince him to use his newfound powers for household chores. Who knew a robotic hand could turn a regular kid into the superhero of the family? Thames & Kosmos, you've given my nephew a bionic boost and turned Christmas into a high-tech adventure! ... show more

My son is 12 and with some assistance he assembled this. After is was put together it could not fire any bullets. It seemed like when you would pull the trigger, the green pieces known as E7 did not push the pieces known as D1/D2 (connected to the air cylinder)back far enough create pressure. I disassembled and started at steps 65 to see if something was put together wrong. I didn't see anything wrong, assembled and it still did not fix the issue. I then disassembled the arms and the trigger. I believe this was the problem. On the arms I made sure everything moved freely on the gears. It does say in the directions to not fully tighten the screws. When I assembled the trigger I made sure it extended as far forward as I could get it. I then connected the arms and trigger and things felt better. I then started at steps 65 again, and completed the bionic blaster. The difference this time is the trigger had some resistance like it was ready to fire. I tried it, and it worked!!! It also made the nerf "thunk" sound. Time for a beer or six!!! The last quirk is that you may have to push the air cylinder forward if it doesn't shoot. I added pictures so you see the what the trigger looks like fully extended, the start position of D1/D2 before trigger is pulled, the end position of D1/D2 when the trigger is pulled and the last one pushing on the air cylinder if it doesn't shoot after you have it working. I hope this helps those who could not get it to work. ... show more

    • Lots of Moving Parts - Sometimes
We have purchased almost all of the Thames & Kosmos STEM Experiment Kits, and have had good luck putting them together and learning about how each system works. We purchased the Thames & Kosmos Ultra Bionic Blaster STEM Experiment Kit, and the kids in the family were so excited, because they have had NERF guns for years, and saw this STEM kit as an extension of the dart shooting activities. Due to the many parts and intensive instructions to build this model, it took a couple of well-paced and patient evenings to get this model put together. And then it didn't work. We couldn't get the darts to shoot. We took apart the model, followed the instructions again to reassemble it, and we couldn't get the darts to shoot. There was so much disappointment in our kids, and they left the model sitting where they had been working on it for a couple of days, walked away from it and never went back. After a week, there was no further interest and trying, so it went back in the box and into a closet. Maybe, someday, I can bring it back out, disassemble it again, and see where mistakes were made. Until then, it's in a closet. ... show more

    • Very difficult to operate effectively
Extremely difficult to get it to work properly. We spent an entire day troubleshooting it and still does not work properly. Now the send back window has closed. Very disappointing.
