Welcome to my build thread. This is my first attempt at building a ardurover based on APM 2.5. The RC platform I am building on is an Axial SCX10 rc crawler (2012 Jeep Rubicon). The end goal I am aiming for is large obstacle avoidance. Where this drone can determine if it’s possible to crawl over an object, or have to move around (such as when it cannot get enough traction to climb over an object). I am to understand that for advanced obstacle avoidance and drone orientation to determine if a change of route is required will require the use of something like Raspberry Pi. I own a new Raspberry Pi which I am not using, but would be glad to try in the future. The other thing I am trying to accomplish is keeping everything under the body. This requirement may push me to bump up to quarter scale vehicle. Keeping everything under the body will provide a larger possibility of keeping things protected in case of rollover.

NiCad 3000 mAh battery
Li-Ion 1100 mAh battery
I have made use of the crawler as it is for the last month, and see that some things need to be modified. I am strongly considering some changes to the suspension and drive train to improve the crawler’s ability to climb obstacle. This includes wider axles from an Axial Wrath. Longer suspension links to stretch the wheel base. Longer shocks to lift the crawler. Slightly larger tires to lift the axles further off the ground. And rotating the axles to lift the pinion to point more towards the t-case to minimize drive shaft joint angles.
Currently, the motor and battery system I have now allows for a bit over 2 hrs of run time. On this note, the final thing which needs to be looked at is adding a second motor and a better battery solution to ensure the added weight doesn’t impact performance an drive time in a negative manor.
Thanks for reading,
