How can i change the motors of RP5 Tracked Chassis ?

Hello,

It is possible to change the RP5 motors, but it is not easy to do. Here are some (not particularly promising) posts about changing RP5 motors:

Tamiya 70097 in RP5 Chassis Combination?

Thank you Jan and Ryan, It seems the thought making this platform go faster with minimal cost is not achievable with the RP5. The problem I am having, is that RP5 tracks and gear drive are not balanced, and the unit seems to always drift to one side. I have corrected that by using the aceclerometer to detect X axis deviation and adjust motors accordingly. It works. However, it consumes some processor power(PID loop). I greased the gears, adjusted the tightness of the screws and made sim…

Modifying the RP5 gear drive

Hello. 50 cm/s sounds doable, but I think it will be pretty hard to get a different motor in there. I don't know what the gear ratio of the RP5 is, but 30:1 with the micro metal gearmotors will almost certainly be too low since the 3pi wheels are much smaller, and you need quite a bit of torque if you want to be able to turn. You'll probably want to go with the HP versions, though even those motors are weaker than the stock motors on the RP5. I'm not sure why you said 4mm on the shaft; the…

You will need to find motors that can run at 7-9V, have a 2mm shaft diameter, and can be mounted inside the motor compartment.
