What it can do
Written by Robotheca from the project's documents.
- Remotely teleoperated garbage truck robot controlled by a FlySky FS-iA6B radio transmitter and receiver
- Rear wheel drive with two geared yellow DC motors driven forward and reverse through a brushed DC H-bridge
- Front servo steering through 3D printed control arms with a clamped safe pulse range
- Servo-driven arm with gripper and shoulder joint that slides material into a rotary dumper
- Rotary dumping bucket tipped by a servo with analog control to empty into a large receptacle
- Neutral deadband and exponential throttle smoothing to reduce drift and current spikes
- Failsafe that returns outputs to neutral on signal loss, stopping the motors

Wiring and electronics
Notes written by Robotheca from the project's documents.
Main parts
- Arduino Nano Every microcontroller
- FlySky FS-iA6B receiver with iBUS serial output and matching transmitter
- Brushed DC H-bridge motor driver
- Two geared yellow DC drive motors
- SG90 and MG995 servos for steering, gripper, shoulder and dumper
- LM2596 buck converter providing a 5 V logic rail
- Six NiMH AA cells in series, about 7.2 V nominal, in a battery cage
- Four 1000 µF electrolytic capacitors giving 4000 µF of bulk capacitance
- Custom KiCad control PCB and power distribution board with a physical power switch
Connections
- Battery pack feeds a power switch, then the power distribution board
- Raw battery voltage goes directly to the H-bridge and high torque servos, avoiding the regulator
- Raw battery voltage also reaches the LM2596 buck converter on the control PCB through a soldered harness
- The buck converter supplies 5 V to the Arduino, the receiver and the low torque servos
- Arduino PWM outputs drive the H-bridge and the servos; the H-bridge drives the two DC motors
- Receiver channels map to pins: CH1 steering on D2, CH2 drive on D9 and D10, CH3 auxiliary on D4, CH5 gripper on D3, CH6 shoulder on D5
- Power distribution board and control PCB are joined by two soldered wire harnesses
