Because buying one was too easy, better build and program it yourself!
This project aims to control a RC tank using a programmable board, arduino, and implement the main features of other commercial products such as Heng Long, Toro or Taigen: classic movement, turret rotation, gun elevation, sound, smoke, lights etc.
You can see test videos of implemented features here.
Currently I have a heng long chassis with gearbox (2 DC motors), turret rotation gearbox, airsoft gun unit, sound unit and smoke generator. I control it with a bluetooth ps2 controller and several TB6612FNG drivers. See the wiring-diagram for more details.
Hardware:
- 1 x Arduino mega.
- 3 x TB6612FNG.
- 1 x Heng Long chassis with gearbox (2 DC motors).
- 1 x Turret rotation gearbox.
- 1 x MG90S servo for gun recoil.
- 1 x MG90S servo for gun elevation.
- 1 x Dasmikro TBS Mini sound unit.
- 1 x 8 Ohm speaker.
- 1 x PS2 controller (bluetooth is not necessary).
- 1 x battery (I'm using a 14.5V 2.15Ah from a robot vacuum cleaner).
- A lot of jumper wires.
- DifferentialSteering, available in the library manager.
- TBSMini.
- PS2X_lib.
- arduino-timer, available in the library manager.
- AsyncServo. available in the library manager.
