Gamma rays and X-Rays are basically the same thing - ionizing electromagnetic radiation. Electromagnetic radiation can induce currents in a piece of metal that is moved through its field and these unwanted currents can play havoc with the circuits inside a microchip, perhaps even overloading and burning them out. The gamma rays could also alter the bits in the memory chips so the software running the robot could crash.
