Hi all guys. I am developing a quadruped robot. This robot using: A) n°1 Arduino MEGA 2560 board B) n°1 Adafruit 16ch servo driver board (where I attach & power up the servos) C) n°12 Power HD 1201MG Metal Gear Servos - 13.2 kg (183 oz in), .14/sec
I got great result with my robot walking good; here the result: https://www.youtube.com/watch?v=qv204Chl6ig
All ok but servo motors has some limitations. The fact is that until servo using toothed gears inside so it's very difficulty to make a decent shock absorber system. And in a quadruped robot, a decent shock absorber system is a really important matter.
So I really would to know if, using my Arduino MEGA 2560, I can replace the servos with brushed motors. In fact using brushed motors I can make sure a better shock absorber system due to the fact that no toothed gears are inside a brushed motors.
Then some questions: 1) Can you provide me the name of some brushed motors similar (in torque) to my actual servos? So a motor that can handle 13kg of torque. 2) I know that I can use shields to make my Arduino board handling brushed motors. Can you tell me what is the better shield to handle 12 brushed motors (13kg of torque). 3) Currently in my project I am using 4 tactile sensors + 1 MPU6050 gyro sensor + 2 SRF05 ultrasonic sensors too. So If I will use a brushed motor shield, can I get problems using these sensors?
Thank you in advance for help!
