Wow Wee WowWee 2000 vintage small gray robot battery operated toy

Vintage from 2000 WowWee small gray battery operated robotic toy. I tested it with 4 AA batteries and it seems to be in overall good working condition as you can see in the video. Batteries NOT included. However I don’t know what it was like brand new so there may be missing parts/ parts not working properly, I’m not sure if there was originally a remote etc. Great for collectors or sold as is for parts.
