Summary of accelerometer Based Hand Gesture Controlled Robot using Xbee
This article details a gesture-controlled robot project using two Arduino Unos and Xbee communication. Users control the robot's movement and a robotic arm via hand gestures detected by flex sensors embedded in a glove. The system features long-range wireless capabilities, allowing for remote operation of a mobile base equipped with DC motors and wheels, as well as a pan/tilt robotic claw.Parts used in the Gesture-Controlled Robot:
- Arduino Uno x2
- Xbee S2 x2
- Xbee shield for Arduino Uno x2
- Xbee Explorer Dongle
- Shrink cables x4
- Dual H-bridge SN754410NE
- Flex Sensors x4
- Trolley wheels (30mm) x2
- 12v DC motor x2
- 4AA Battery holder
- 8AA Battery holder
- 5V regulator
- Battery cables
- Robotic claw
- Robotic Claw Pan/Tilt Bracket
- Servo for robotic claw
- Spacer studs x8
- Button
- Glove
- Regular rc wheels (55mm) x2
- Regular switch
- Aluminium plate
- Cables

Step 2: Base Model
I made a simple drawing in SolidWorks and then went to a local ironmongery to get the plate bended.
Structure
On the base plate under the plexiplate is were the two DC motor will be placed. Over that will the 12v battery holder and the H-bridge fit. And on the top level will the Arduino be mounted. In the middle of the plate will the robotic arm be placed.
The drawing model is included.
