Review on Stainless Raspberry Chassis Platform by KOOKYE by Mike Groover

Great. No problems with obstacles. Much energy. I was concerned reading some of the other reviews but I think maybe they were just having trouble with their outline. I have pi, arduino, 4 custom servos, lcd touch screen, l298n, ptz night vision camera, hc05-bt module and breadboard. Full freedom of movement with Arduino, hc05 and Bluetooth app. I have DC encoder motors that run on 12V using only red and black wires and a $7 l298n motor controller with a fairly small Dewalt Max lithium battery. It steps down to 5v for the Arduino and Arm servos, and also via the same l298n. It runs more than 20 minutes on a single charge. The Pi starts the camera/recording and some other functions and turns off its own hat/3.3V power. All in all, it's pretty heavy and still has power. The motors run at 225 digital write speed for full forward and reverse speed. Left/Right rotates the same speed in reverse direction of only one motor. Forward and Spin I just changed the speed of a motor to 180. So the forward speed on the left is 180 speeds for the left motor and 225 for the right motor in the sketch. Check out my videos. Very happy with it. I wish the tracks were softer. Rigid plastic glides on smooth surfaces. I put big rubber bands on the tracks, it helps a lot
