The Hydrobot is a robotic arm building kit for the budding engineer in your family.
It might seem like a daunting thing for your children to undertake at first but any child over the age of 10 should have no problem following the instructions and getting it together on their own.
In fact, even if it does require you to help out your child, it gives a great chance to spend some quality family time together.
Once assembled, the arm can do some pretty impressive stuff. Your child can move the arm to grip objects, and it even has a suction cup that can pick things up.
As the name 'hydrobot' suggests, this toy's movement is powered by water, giving your child the chance to learn about hydraulics.
This would be an excellent gift for anyone who loves technology.
