Description
in this project Gesture Control Robotic Hand 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.
Gesture Control Robotic Hand
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.
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.
