One important feature of MOSFET transistors is that they contain an intrinsic (unavoidable, built-in) diode between their drain and source. This diode acts as a catch diode in an H-bridge configuration, and most MOSFET datasheets specify the parameters of this diode. It is thus possible to use this built-in diode of the transistors and not provide external ones if the specification of this diode meet the design requirements. For bipolar transistors there’s no such intrinsic diode so external diodes always have to be provided.

Robotics is the branch of technology that deals with the design, construction, operation, structural disposition, manufacture and application of robots. Robotics is related to the sciences of electronics, engineering, mechanics mechatronics, and software

Robotics Short Story
The word robotics was derived from the word robot, which was introduced to the public by Czech writer Karel Čapek in his play R.U.R. (Rossum's Universal Robots), which premiered in 1921.
According to the Oxford English Dictionary, the word robotics was first used in print by Isaac Asimov, in his science fiction short story "Liar!", published in May 1941 in Astounding Science Fiction. Asimov was unaware that he was coining the term; since the science and technology of electrical devices is electronics, he assumed robotics already referred to the science and technology of robots. In some of Asimov's other works, he states that the first use of the word robotics was in his short story Runaround (Astounding Science Fiction, March 1942). However, the word robotics appears in "Liar!"

yo necesito un variador de velocidad para un motor de CC, de 24 VDC. 8 kilowatios, tipo serie , escobillas. No he encontrado mosfets, que me soporten corrientes mayores a 100 amps. para colocarlos en paralelo, para sumar corriente, o un puente H para 300 amperios. De antemano les agradesco la información que puedan suministrarme. Atte.: DARÍO BURITICÁ. M.
