Robot Arm Kit Toys, Flexible Remote Control Robotic Arm with 360° Gripper and Wheels, 2 in 1 Science Kit Best Bithday Gifts for Kids Adults, No Assembly Required (with Gift)

Most of the little parts have one additional spare - this really helps. A solid instruction makes an assembly process easier. Plenty of space for additional electronics to tinker with. Great value for a $.

I have ordered 4 different robot kits from different manufactuers. All have had parts missing. I am keeping this last one and buying the missing nuts from the local hardware store. I have no choice since our competition is next week. I returned the other 3 and have yet to recieve a refund. These kits are expensive and worthless. I am a long time Amazon prime customer and have never had problems such as these. When they raised the membership fee, I stayed. When Amazon stopped 2 day shipping, I stayed. These products are about to push me away for good. Amazon should do better. These shoddy Chicom companies shouldn't be sold on this marketplace.

Got K3-X. It came almost completely assembled, with two precharged batteries, two claws, a spare motor and a gift stand. I had to attach the claw and install the batteries. I had to use my own AAA batteries for the control. Worked fine for 30 minutes, then one of the motors failed. I was able to replace the motor with a spare one. See the second picture. Wondering what exact type of motors and gearbox used there to have one more item if another one fails.

This robot was a requested gift. Both the recipient and his dad (a robotic coach) we're thrilled to get this. Without assembling anything to date, the coach was impressed and indicated they would probably use it as depicted on the box.

They sent me everything I wanted they even threw in an extra gripper claw very very high quality coated aluminum I love it so much can't wait to build it

Where was this thing when I was a kid? I had so much fun playing with this thing as an adult! I was not looking forward to the assembly process but I was pleasantly surprised when it came completely assembled, just had to attach the claw and battery. There are two included batteries so you can charge one while playing. I was able to pick up the controls pretty quickly and it's FAST! It's a little disappointing you can't give multiple inputs at once although it does have some unique movement ability, like how it can move diagonally. The gripper isn't super strong as I wasn't able to open doors or move heavy objects but I was able to carry a beer can. The arm reaches quite tall when fully extended and comes down flat, and if you get tipped over you can use the arm to get back up usually. I would have also appreciated a rechargeable controller with a camera.

If I can get the batteries to charge, then this probably would be a great toy for my 2 sons. Every USB port that I have tried to charge the batteries should have worked. The design for the USB charging is horrible. The company who designed the charging ports did a horrible job. The charging ports for this product SHOULD NOT! and I repeat SHOULD NOT! be USB. It Should be an AC adapter. HORRIBLE JOB!! Way to loose on the connection batteries don't charge.

Hola, compre este maravilloso objeto que me ha servido para estudiar ciertos detalles de robótica. Desafortunadamente el control remoto dejó de funcionar. Después de intentarlo cambiando baterías….decidi intentar arreglarlo y fue imposible. Como puedo potente un control nuevo ?
