The basic features of the ERS-2100 are almost the same as in the ERS-1100. The robot is a quadruped and is equipped with a color camera, stereo-microphone, acceleration meters, and gyro meters. CPU power is improved from about 100-200 million instructions per second (MIPS), and main memory is extended from 16-32 MB.

At first glance, optically no difference to 210. But if you look a little closer …

…the core is absolutely different. Another kind of memory stick reader and the legs are slightly different too. All the parts are not interchangeable with the ERS210. Unfortunately, this model is no longer functional.
