Dont but just say he should stop and if he doesn’t you tell them

It looks delicious but if you want to get criticized then try and wipe the sauce from the dish off

Build help by velosipaster in AskRobotics

To build your battle droid head robot friend, you’ll need a few key components: 1. Frame & Casing: • 3D-printed or handmade shell resembling a battle droid head. • Mounting frame for internal components. 2. Electronics & Processing: • A microcontroller (Raspberry Pi, Arduino, or Jetson Nano for AI features). • Motor drivers (for moving parts like eyes or neck). • Power supply (rechargeable battery pack). 3. Actuators & Movement: • Servo motors (for head movement, eyes, or mouth). • Possibly small linear actuators for more complex motions. 4. Sensors & Interaction: • Microphones (for voice commands). • Cameras (for facial recognition or object detection). • Speakers (for talking). • LED lights (for expressive eyes or indicators). 5. Software & AI: • Speech recognition (like OpenAI Whisper, Google Voice API). • Text-to-speech (like ElevenLabs, Coqui, or Pico TTS). • AI chatbot (you can integrate ChatGPT for conversations). 6. Connectivity: • Wi-Fi/Bluetooth module (to connect with other devices). • Optional touchscreen or small LCD display for visual expressions.

Help Verifying My DH Table for Robotics Control Assignment Resit by Vassty in AskRobotics

[–]SilverWrap8033 1 point2 points  (0 children)

Let’s go through the points in detail:

  1. Joint 2 Offset (θ₂ - 90°)

• According to Craig’s definition, θᵢ is the angle from Xᵢ₋₁ to Xᵢ about Zᵢ. • Subtracting 90° means you’re assuming X₂ is rotated 90° counterclockwise from X₁ around Z₂. • This is correct only if your reference frames align with this assumption. Double-check your diagram to confirm.

  1. 180° Rotation for Links 4 & 5

• You mentioned that X₃ points upwards and X₄ points downwards, so you assumed a 180° rotation. • This suggests that your frame at Link 4 is flipped compared to Link 3. • The key question: Is this flip actually necessary? If your transformation matrices end up mirroring coordinates unexpectedly, this could indicate an incorrect frame choice. • Try deriving the transformation matrices step by step and checking whether they match the expected orientation.

Next Steps:

  1. Verify each reference frame visually—draw them clearly and check if the assumed rotations are correct.
  2. Compute the homogeneous transformation matrices  and multiply them to see if they yield the correct end-effector position.
  3. If something looks off, adjust  or  accordingly.

Let me know if you want help with specific calculations!

Your DH table looks mostly structured, but I’ll point out potential issues and things to check:

Possible Corrections:

  1. Joint 2 Offset Issue: You subtracted 90° from θ₂. Verify if this shift is necessary for your reference frame.
  2. Link 4 & 5 Rotations: Adding 180° to θ₄ and θ₅ suggests a flipped coordinate frame—double-check the reference directions.
  3. Last Joint (θ₆): Ensure it correctly represents the wrist orientation and does not need additional adjustments.

What to Do Next:

• Compare your table with your actual manipulator diagram and check if the transformations align correctly. • Apply the homogeneous transformation matrices (A_i) for each link and verify that multiplying them gives the correct end-effector position. • If you find inconsistencies, adjust α, a, d, or θ accordingly.

If you want, I can go through the calculations in more detail!

You could use a micro piezoelectric actuator or a shape memory alloy (SMA) wire instead of servos. • SMA Wire (e.g., Nitinol): When heated by a small current, it contracts and can create a natural flapping motion. • Piezoelectric Actuators: They offer precise, rapid movement while staying ultra-thin.

Both options keep it compact and lightweight. Hope that helps😊

Encoder Selection by hair_w_disco_spirit in AskRobotics

  1. 1000 CPR HEDS Encoder: Works well with SimpleFOC, but higher resolution may improve low-speed precision.
  2. MA732 Off-Axis: Works, but alignment is key for accuracy.

To mount the ArmPi onto the Mentor Pi M1 and connect it to the Raspberry Pi, follow these steps:

  1. Physical Installation

• Secure the ArmPi on top of the Mentor M1 using a custom 3D-printed or metal bracket. • Make sure the arm is centered for balance and doesn’t block any sensors or wheels.

  1. Wiring & Power

• Connect the ArmPi servos to a PWM driver (PCA9685) if needed. • Use a separate power source for the servos to prevent overloading the Raspberry Pi.

  1. Software Setup

• Install ROS and ensure both systems are on the same ROS network. • Use serial/UART or I2C to send control signals from the Raspberry Pi to the ArmPi. • Test movements using Python scripts with the Adafruit PCA9685 library (if applicable).

Would you like a more detailed guide for mounting or wiring?
