A stand with three legs called atripod
The number of legs in a rig can vary depending on the type of rig. For example, a common offshore drilling rig typically has three or four legs, which provide stability and support. In contrast, land-based rigs usually have a more simplified structure and may not have distinct legs at all. Ultimately, the specific design and purpose of the rig determine the number of legs it has.
"without legs"
No it is not necessary that all robots have arms and legs. Some robots have only arms and some have legs and some have wheels for their mobility. Basically it depends on the requirements as the requirements dictate how we design our robots. For example in automobile industries robots are used only for welding purposes or in paintshop. These types of robots have only arms not legs.
In case of a bipolar junction transistor, we have only three terminals (legs). They are emitter, base and collector. But, in case of a MOSFET (metal oxide semiconductor field effect transistor), we can have four legs. They are source, drain, gate and substrate. The substrate is not being shown in some notations of MOSFET. But it does exist. Hence, a MOSFET has four legs.
