Robotic Hand With Wireless Glove Controlled | NRF24L01+ | Arduino

In this video; 3D robot hand assembly, servo control, flex sensor control, wireless control with nRF24L01, Arduino receiver and transmitter source code are available. In short, in this project we will learn how to control a robot hand with a wireless glove.

Step 3: 3D Models of the Hand and Forearm

The hand is part of an open-source project called InMoov. It’s a 3D-printable robot, and this is just the hand and forearm assembly.

For more information, visit the official InMoov website. You can visit the “Assembly Sketches” and “Assembly Help” pages in the InMoov website for more details on assembly.

Anet A8 3D Printer is used in this project. Models were printed at the lowest qulity.

Step 4: Assembly of Parts

Assembly of robotic arm parts is very detailed and complex, so you can visit the “Assembly Sketches” and “Assembly Help” pages in the InMoov website for more details on assembly. it is explained very thoroughly on the InMoov website. Or you can watch the video I shared.

Consider this suggestion for the correct finger angle:

When assembling the fingers, make sure the parts are oriented correctly before gluing. Keep all servo motors at 10 or 170 degrees before attaching the servo pulleys to the servo motors. When mounting the servo pulleys, keep fingers in the closed or opened position (according to your servo angles). Then wrap around the servo pulley until the braid wires or strings becomes stretched.

Step 5: Connections of Hand (Receiver)

  • At this point, the servos should already be mounted into the forearm. To connect them to the power supply and Arduino, you can use a small breadboard.
  • Remember to connect the negative on the breadboard to the Arduino’s GND. All the GNDs in a circuit need to be connected for it to work.
  • I recommend using the power adapter for the nRF24L01+ module. Otherwise, communication may be broken due to insufficient current.
  • If you encounter the these problems: vibration in servo motors, servo motors not working, communication breakdown and in similar situations, supply your Arduino board with external power (like USB).
  • If you used different pins than pins shown in below, change them in codes.
  • Connections of the Servo Motors:

Servo-1 connect to the analog 01 (A1) of the Arduino.

Servo-2 connect to the analog 02 (A2) of the Arduino.

Servo-3 connect to the analog 03 (A3) of the Arduino.

Servo-4 connect to the analog 04 (A4) of the Arduino.

Servo-5 connect to the analog 05 (A5) of the Arduino.

  • Connections of the nRF24L01 Module:

VCC connect to the +5V of the Arduino.

GND connect to the GND of the Arduino.

CE connect to the digital 9 pin of the Arduino.

CSN connect to the digital 10 pin of the Arduino.

SCK connect to the digital 13 pin of the Arduino.

MOSI connect to the digital 11 pin of the Arduino.

MISO connect to the digital 12 pin of the Arduino.
