I purchased this two-legged walking robot about 20 years ago with the intention of building it, but unfortunately, I gave up after it took only two steps. It's an HSWB-01 that I've kept at home ever since. This is a very niche product, so I'm not sure if there's any demand, but please consider it if you're interested. I don't have an environment to test its operation, so it's untested. It might be suitable for those who want to restore the robot from that time or use it for parts. There is no instruction manual, but there is a CD-ROM with the control software (compatible with WIN and Mac). However, it's likely that it won't work on newer operating systems. Please understand that this is a 20-year-old used item before purchasing. Shipping will be via Yu-Yu Mercari (anonymous shipping). It will be wrapped in plastic for waterproofing and carefully packed with cushioning material. I work during the weekdays, so my replies may be delayed, but I will respond as quickly as possible within 24 hours. #TwoLeggedRobot #Robot #ControlBoard #MotorDriver #HimejiSoftWorks #HSWB01 #RS232CConnector #32ch #RobotEnthusiast #Electronics #RetroHardware #JunkItem #ForEngineers #Hobby
