ACEBOTT QD007 Robot Arm Pack Smart Car Expansion DIY Kit For QD001

Specifications

• Model: ACEBOTT QD007 Expansion Pack.

• Degrees of Freedom (DOF): 5-Axis Movement (Base Rotation, Shoulder, Elbow, Wrist, Gripper).

• Actuators: 4x SG90 Micro Servos (Joints) + 1x Gripper Servo.

• Control Interface: Connects to ACEBOTT ESP32 Shield (PWM Servo Ports).

• Gripper Range: Opens approx. 45-50mm (Fits standard blocks, ping pong balls).

• Payload Capacity: Designed for lightweight objects (foam blocks, small plastic items).

• Mounting: Specialised mounting plate for QD001 Chassis.

• Compatibility: Strictly for Smart Robot Car Kit (QD001). (Not a standalone product).

Project Evolution

• Prerequisite: You must own the ACEBOTT QD001 Smart Car Kit. This pack does not function without the car's battery and controller.

• The Upgrade: This moves you from 2D robotics (driving on a floor) to 3D robotics (manipulating space). You will learn Inverse Kinematics basics—calculating how to move three joints to reach one specific point in the air.

• Effort Level: Intermediate. Requires assembling the mechanical arm structure and cable management.

Virtual Technician & Wiring Guide

• ⚠️ Power Warning: Servos draw significant current. Ensure your 18650 batteries are fully charged before operating the arm. Low voltage will cause the ESP32 to reset when the arm tries to lift.

• Pin Mapping: The servos typically connect to the dedicated Servo Header on the ESP32 Shield.

  • Base Servo: Pin 13

  • Shoulder Servo: Pin 12

  • Elbow Servo: Pin 14

  • Claw Servo: Pin 27

  • (Note: Verify exact pin definitions in the ACEBOTT code/manual as they may vary by shield version).

Frequently Asked Questions (FAQ)

• Can I use this arm without the robot car? No, it is designed to mount on the QD001 chassis and uses the car's controller.
• Does it come with servos? Yes, it includes all 5 servo motors required for operation.
• What is the maximum weight it can lift? Approx. 50-100 grams (lightweight objects only).
• Is the car included? NO. This is the expansion pack only. You need the QD001 kit.
• How do I control the arm? Via the ACEBOTT Mobile App (Bluetooth/Wi-Fi) or IR Remote.
• Is it difficult to build? It involves many screws and small parts. Expect 45-60 minutes of assembly time.
• Can I program it with Python? Yes, if you are running MicroPython on the ESP32, you can control the servos using standard PWM libraries.
• Do the servos jitter? Minor jitter is normal in hobby servos. Ensure batteries are charged and cables are not tangled.
• What material is the arm made of? Laser-cut acrylic or engineered wood (depending on batch), sturdy enough for education.
• Can it rotate 360 degrees? The base servo is 180 degrees, allowing a wide sweep but not full continuous rotation.
• Does it block the ultrasonic sensor? No, the mount is designed to sit behind/above the front sensors.
• Can I use it with Arduino Uno? Physically it mounts to the ACEBOTT car. Electronically, you can drive it with any PWM pin, but the mounting is specific.
• Are the gears metal or plastic? The SG90 servos use nylon (plastic) gears. Avoid stalling them to prevent stripping.
• How wide does the claw open? Enough to grab a standard 40mm calibration cube or ping-pong ball.
• Does it need an extra battery? No, it shares the 2x 18650 batteries from the car.
• Can I add a camera to the arm? It's not recommended; the servos are not strong enough to hold a camera steady.
• What happens if I wire it backwards? You may damage the servo. Always check Brown(GND), Red(VCC), Orange(Signal).
• Is code provided? Yes, ACEBOTT provides demo code for "Pick and Place" operations.
• Can I extend the wires? The servo cables are usually long enough for the car.
• Is this good for a final year project? It is great for a sophmore/mini-project. For final year industrial simulation, you might need a metal arm.
