			===TO DO==

			* Need to pick a wheel shaft and motor mounting design, idealy from older LifeTrac designs.
			* Need to fix mounting of bucket
			* Need to adopt quick attach design
			* Need to place a plate at the bottom of the machine, connecting the the side wall plates. possibly like the back of the machine.
			* Need to place the crossbeam so that the hydraulic arms bottom out when the bucket or quickattach plate almost collides with front of arms.
			* Need to decide on engine mounting.
			* Fix hole mismatch for middle vertical cross plate
			* Fix front of bucket, removable blade piece? find an off the shelf option.

			== Machine Design ==

			LifeTrac v25 is a remotely-operated compact utility loader designed as an open-source alternative sized between a Toro Dingo and a Bobcat. Built using parametric OpenSCAD design, it features modular construction following Open Source Ecology principles.

			=== Key Design Features ===

			* '''Modular Construction:''' Plate steel, square tubing, and angle iron components for easy fabrication and repair
			* '''Remote Operation:''' No operator seat required, optional standing deck for manual operation
			* '''Hydraulic Power:''' 4 independent wheel motors for all-wheel drive, 2 cylinders for arm lift, 2 for bucket tilt
			* '''Open Source CAD:''' Complete OpenSCAD parametric design files for customization and manufacturing

			=== Technical Specifications ===

			! Specification !! Value
			\|-
			\| '''Hydraulic System Pressure''' \|\| 3,000 PSI
			\|-
			\| '''Estimated Lift Capacity''' \|\| ~1,200 kg (~2,646 lbs)
			\|-
			\| '''Drive Configuration''' \|\| All-wheel drive (4 hydraulic motors)
			\|-
			\| '''Cylinder Bore (Lift)''' \|\| 63.5 mm (2.5")
			\|}

			=== Weight Estimate ===

			Machine weight is estimated at '''800-1,000 kg (1,760-2,200 lbs)''' based on steel construction with:

			* 1/4" (6.35mm) plate steel for most components
			* 1/2" (12.7mm) plate steel for high-stress areas
			* 4"×4"×1/4" square tubing for main frame
			* 3"×3"×1/4" square tubing for loader arms

			== Features ==

			* '''Multiple Control Modes:''' Switch for MQTT/OFF/BLE mode selection (BLE default)
			* '''BLE Direct Control:''' Direct Bluetooth connection to DroidPad app (no WiFi/broker needed)
			* '''Remote Joystick Control:''' Dual joystick setup for tank steering and hydraulic functions
			* '''DroidPad Compatible:''' Native support for DroidPad via BLE or MQTT
			* '''WiFi Communication:''' Reliable wireless control with MQTT protocol
			* '''ROS2 Integration:''' Control LifeTrac from BeagleBone or any ROS2-enabled device
			* '''Configurable Flow Control:''' Choose between single or dual proportional flow valves via jumper
			* '''Proportional Flow Control:''' Speed regulation based on joystick input intensity
			* '''Safety Features:''' Emergency stop, communication timeout, and fail-safe operation
			* '''Status Monitoring:''' Real-time system status and diagnostics

			== Control Scheme ==

			=== Tank Steering ===

			* '''Left Joystick Y-axis:''' Forward/backward movement for both tracks
			* '''Left Joystick X-axis:''' Differential steering (left/right turns)

			=== Hydraulic Functions ===

			* '''Right Joystick Y-axis:''' Arms up/down control
			* '''Right Joystick X-axis:''' Bucket up/down control

			=== Speed Control ===

			* '''Proportional Flow Valve:''' Automatically adjusts system speed based on maximum joystick input
			* '''Deadzone:''' 10% deadzone prevents unwanted movements from joystick drift

			== GitHub Repository ==
