Dear Robotics Experts,
I am looking for high torque continuous servo motors for a all-wheel drive mobile robotic platform. Total weight of the platform will be approximately 30kg, including batteries.
This platform will be used for robotics experiment (not for game) and I want to be able to control all wheels accurately both in speed and position modes.
I've considered using geared DC motors with encoders, DC servo drivers and motion controllers. I've also considered using Dynamixel RX-64 continuous turn servo motors which can be daisy chained and all motors can be controlled with a single RS485 line. This is an easy solution but an expensive. Because as you can see on the following URLs Dynamixel RX-64 is expensive.
Merci,
Roberto
