This is a Construction Toy used mostly in Education and Industry as a tool for modelling and demonstration.
It comes with beams, and fixing pins/clips. There is an array of wheels, cogs and mechanical parts. They have motors, robotic controller blocks and Pneumatic parts. one of the best range of small scale devices including Solenoid valves and cylinders. It has a more adaptable construction system than Lego, and makes for sturdier more rigid constructions. However, it is also more expensive.
You are advised to seriously consider FischerTechnik for your robot designs if you are going to be using small scale pneumatics - simply because they have the best range of parts for this kind of application. They are on of the few systems that have Solenoid valves as well as manual valves and cylinders. It is common to see the pneumatic range used with other Construction Toys.
Time to build your own robot! Using a Raspberry Pi with parts and some time, you can use my book to learn how to make and program a robot with automatic behaviours.
