A Hand Gesture Controlled Robotic Arm

General Description: Control a 3D printed robotic arm wirelessly using hand gestures.

Specific Description:

A transmitter circuit is attached to a glove that contains an IMU, flex sensor and Arduino Pro Mini. The MPU6050 IMU detects wrist rotation and hand tilt while the DIY flex sensor detects finger bending. The movements are detected and sent to the receiving circuit through the NRF24L01 transceiver.

The receiver circuit decodes the data coming from the transmitter and moves the four-servo robotic arm accordingly.

  • 1 × Arduino Pro Mini Transmitter main microcontroller. Chosen because of size.
  • 1 × MPU6050 IMU. Detects hand movements.
  • 1 × Flex Sensor Electronic Components / Misc. Electronic Components
  • 1 × 5v to 3.3v Converter For the NRF24L01
  • 1 × NRF24L01 Transceiver Sends data to the receiver circuit

    May 3: Considering NodeMCU for both transmitter and receiver. Established communication but delay is very significant.

    May 8: Purchased XD-RF transmitter and receiver. Somehow can't get it to work. Also, the frequency might be to low and susceptible to interference.

    May 15: Decided to buy NRF424L01. Works with a very short delay time. Range is surprisingly good.

    May 17: Started building the transmitter circuit. MPU6050 reading works quite well.

    May 18: Built the receiver board. Works well but messy.

    May 19: Decided to buy Arduino Proto Shield for the receiver. Also bought adapter for NRF24L01.

    May 22: Created optical flex sensor. Works but needs constant sensitivity adjustments.

    May 23: Finished transmitter board and attached to glove.

    May 24: Finished project
