Version 0.1 wiring complete! APM2.5, Firgelli actuator controller, spektrum rc reciever, 900mhz telemetry, and wiring for headlights, steering wheel, throttle and IR distance sensor all done.
Easy on/off switch (with key) and usb socket for convenience in reprogramming!
Final Wiring
Main power switch and underside of USB
Project power wheels’ brain! APM2.5 (ardupilot), firgelli linear actuator controller, spektrum 3 channel receiver and 900mhz wireless telemetry.
APM2.5 is running completely new code written by me (last night) with 3 modes. Full RC, RC throttle + Jeep Steering wheel (via potentiometer and analog input) and full Jeep
Project power wheels, almost fully assembled.
Over the next few days I will be working on the code to run on the APM2. Last night I started a skeleton codebase, using the ardurover code to map the initial includes/setup and loop structure. But aside from the imported libraries and
Steering buildout complete!
After much fussing with the frontend trying to get it to drive straight consistently we decided to make the drag link adjustable. Along with the aluminum plates and welded bolts to the front axels the frontend is now nice and stiff, and tracks great.
Last night i finished up the wiring and we got the APM2.5 mounted in the rear.
First iteration is just using a servo cable Y to the rear ESCs (just signal for second ESC), this will eventually become a separate output channel on the APM, and a signal cable
Max has been working on removing the slop from the front end. I guess the amount of slop is acceptable when its using the plastic wheels and slow motors, but as we have ramped everything up and are now using rubber tires the slop has led to some pretty unpredictable
New and MUCH improved steering assembly. The linear actuator is driving the left hub directly with the drag link (original control bar) to the right hub.
My new linear actuator for steering arrived today. Max is busy fashioning the new steering assembly that we discussed over lunch.
Here is a size comparison between the old and the new :)
