Might put this higher up in your comment. Dynamixel robotics servos exist, but at Dynamixel prices.
Weird stuff has weird prices. If anyone made a useful home robot that sold millions of units then robotics servos would get rapidly cheaper, but that hasn't happened yet.
- HeyLaughingBoy 4y agoThis is an important point. The low prices of a lot of hobbyist-grade motors and motor controls are driven by their use in consumer electronics. I can buy an entire 4-axis stepper motor controller with drivers for under $100 because they are made by the thousands for laser cutters and 3D printers. OTOH a similar professional controller will set me back at least a few hundred $$, if not a few thousand due to being designed for a harsher environment and for higher reliability.
- relaxing 4y agoiRobot has sold millions of Roombas. Wonder if there's been any economy of scale bleed-over from that work.
- sbierwagen 4y agoRoombas don't use any servos. Just a couple of regular brushed DC motors. They do sell a blank chassis for classroom stuff: https://edu.irobot.com/what-we-offer/create3 https://edu.irobot.com/what-we-offer/create3
