what was the robots name on "lost in space"?

Answer 1

The Robot, a Model B-9 Environmental-Control Robot, which had no given name. However, in the third-season episode entitled "The Time Merchant," it was shown in its packing crate, and the crate was labeled ONE General Utility Non-Theorizing Environmental ROBOT, with the G, U, N, T, and E, and all letters in ROBOT in red capital letters, while all the other letters were black; some have suggested that this was supposed to convey the acronym GUNTER.

Answer 2

Just Robot.
Although it was a spin off of Robbie the Robot from Forbidden Planet.
Robot the Robot - Robot (Serial No. 1A1998) on the sci-fi adventure LOST IN SPACE/CBS/1965-68. "Robot" was the generic name given to the mechanical environmental control robot servant onboard the spacecraft Jupiter II which was programmed to serve its crew (The Space Family Robinson) as it flew to the Alpha Centuari galaxy. On the series' first episode, the robot's circuitry was modified (by a stowaway) to kill the crew when the ship was launched, but the plan failed. Robot had retractable arms, a domed-head with twinkling lights, pincher type hands which could shoot a lethal charge of electricity, and tank-like treads which conveyed it to and fro. Waving its accordion-pleated arms, the robot often shouted such programmed phrases (voice of Dick Tufeld) as "Warning! Warning!" and "Danger, Will Robinson! Danger! Danger!" Robot needed eight hours of rest to recharge his system.
