I want to build a wheeled locomotion so if i buy these stiffs it’s enough:
1- SpringRC SM-S4303R Continuous Rotation Servo.
2- Shoulder Bolt with Flat Washer and Hex Nut.
3- Miniature Track Link and Pin.
4- Injection-Molded Sprocket Set 8T Futaba.
or i need more equipment for build the mechanical part in my robot.
waiting for reply
