This V2 of the project i am working on currently. I cant make changes to it because of the recent LMR update :(. This Variant is now a 6wd instead of 4wd. same types of wheels but i am using coreless motors. for better efficiency and high torque.

NEW MOTORS!!!
The drill motors that i had on previously were too powerful to "trust it" to drive itself autonomously, and it was too twitchy to be driven in tight spaces. I then found better motors suiting my robot.. The ones that i have now are Japanese Namiki motors. 22mm in diameter but they produce 5kgcm continuous torque and stall of 16kgcm each, making them very suitable for the robot should it get heavier.
Extra Wheels
The chassis as assembled. One of the motor mounts needs a little tweaking.
Navigates autonomously or via wireless control, gathers and stores sensor data and sends telemetry
