The new design of the 6WD mobile platform, the vehicle uses 2mm aluminum alloy, aluminum spray surface treatment. 6 high-speed DC motor (original 17000 rpm), with 1:34 full metal gear box, so that the car to obtain strong off-road performance.
Shock absorption design is the highlight of the car, the use of 6 damping shock absorber fixedly connected to the body to the car, so that the platform for better roadability, especially for some complex bumpy road.
6WD mobile platforms can be installed with different types of control boards or controllers such as Arduino or Raspberry Pi. The upper chassis uses a 3mm mounting hole, horizontal 12mm, vertical 14mm pitch can be a wide range of mounting a wide range of sensors, or additional expansion of other functions, such as the installation of a robot. The upper floor reserved Arduino platform, raspberry pie platform installation holes.
Step 1: U-type Bracket Assembled Down Platform
Install the remaining 2 brackets in this way, with the retaining hole in the circle position
- M3x8mm screw X 12
- M3 nuts X 12
Step 2: Install U-bracket and Motor Bracket
Screws, nuts and bearings for a single amount, a total of 3 groups.
- M3x10mm screw X 4 (12)
- M3 locknut X 4 (12)
- Flange bearing X 4 (12)
Step 3: Install Six DC Motor
Couplings installed on the motor shaft, the screws are fixed on the side of the platform, the red circle in the color of the side
- JGA25-370 high speed motor X 6
- Coupling X 6
- M3x6mm screw X 4 (12)
Step 4: Install the Copper Column to the Lower Chassis
- M3x30mm copper pillars X 8
- M3x 6mm screw X 8
Step 5: Shock Absorbers on the Assembly to the Chassis and Up and Down the Chassis Together
- Shock absorber X 6
- M2.5x16mm screw X 6
- M2.5 locknut X 6
Fixed the chassis on the copper column,shock fixed onto the motor bracket
- M2.5x14mm screw X 6
- M2.5 locknut X 6
- M3x6mm screw X 8
Step 6: Install the Wheels and Switch to Complete the Installation
- Switch X 1
- M3x6mm screw X 8
Step 7: Hardware Parts
Because use high speed motor, so we also need large current drives and Li – Po, choose the limit current 23 a motor driver, this module need two, we will be one sided motor received M + positive, negative answer M – (group 3 motor), so convenient we control our robot.
The main control board chooses Arduino UNO R3, and if you need more interfaces, you can use Mega 2560 or Raspberry Pi.
If you want to control the robotic arm, you can use the steering gear controller to control it through the UNO serial port;Of course you need a 6v power supply for your steering gear.You can add the robotic arm program to the PS2 and control with the handle to grab what you want.
MD04:
- Working voltage: 5.9-30V
- Working current: 23A
- Logical input: 1.8v, 3.3v, 5V (Max)
- PWM frequency: 100kHz
