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 Robot Arm (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 $.

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.

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.

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

My 6month old loves these! My husband and I also love these, they can be very entertaining. cool shapes and colors! They each have a letter on them with an animal that corresponds with the letter. The animals each have a little design to em. Totally worth the money.

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 ?

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.
