水圧で動くロボットアーム あおぞら

I bought this for my grandson for Christmas, and he thoroughly enjoyed building it and playing with it.The instructions were clear and the parts were accurately made, so the assembly was straightforward and fun as he saw the machine coming together, and everything moves smoothly now that it is assembled.He likes the way that you can use it to carry out procedures that are several steps - grabbing things, picking them up, moving them and setting them down again - he used it to build a stack of toilet rolls. His 4 year old sister has also joined in playing with it, and learning that you have to carry out a series of steps in the right order in order to complete a task.I would suggest that because the pipes need to be a tight fit on the syringes, that you put the pipes in some warm water for 10 minutes to soften them up a little before pushing them on the syringes.

Loved building this with my eight year old. Needed some adjustment at the end due to me not fully understanding the diagrams and we also needed gorilla glue on one part but once built it kept my son entertained for a large part of Boxing Day.
