Reverse pendulam using Rpi,Arduino and additional 0.75kg - which rover 5 chassis to buy
August 22, 2013
i am trying to built a autonomous car ( which can also be controlled by wifi) using DAGU rover-5 chasis , dagu 4 channel motor driver , raspberry pi (for wifi and camera) and arduino uno. i also like to use the same platform for inverted pendulam project using MPU6050 which is my next stage target , so the car needs to be very swift or agile to maintain the balance and change the direction.
including all the circuitry (motor driver , arduino , raspberry pi , servo , sensor , lipo , converter , regulator and acrylic plates , breadboard) i think i will add additional 700-1000gm weight on top of the chassis.
dagu rover 5 platform comes in 3 variants:
1) chassis with 2 motor , no encoder
2) chassis with 2 motor , 2 encoder
3) chassis with 4 motor , 4 encoder
i am confused , which one will suit my requirement , whats the advantage of having 2 extra motor - more thrust/speed? please keep in mind the weight it might carry and speed it needs for swift movement. well i dont need precise outcome. is "2 motor no encoder chassis" ok for my project or should i buy the other ones?
do i really need encoder , or its god to have for future?
