Introduction: Strider Camera Robot V6
This Instructables show how to build Strider Walker V6.
Supplies
- TTGO T-Journal ESP32 Dev Board
- OV2640 or OV3660 camera module with a little bit longer FPC
- Two 4.3g servo with 360 degree rotation option
- Two 801525 Lipo batteries

- SMA Coaxial PCB mount Jack
- A short SMA Antenna
- Around 60-100 pieces of 4mm (actually 3.6mm) M1.2 screws
Step 1: Paperclip Axis
- Straighten the paperclip and cut into 2 pieces
- Keep 24mm straight and belt remaining into a handle
- Repeat to make 4 paperclip axis
Step 2: Servo Patch

Step 5: Legs Assembly
Picture 1: leg1-4
Picture 2: connect leg2 and leg3 with screw
Picture 3: then connect to leg1
Picture 4: connect leg3 and leg4 with screw
Picture 5: repeat Picture 1-4 to assembly 1 more
Picture 6: connect leg2 and leg4 with screw
Picture 7: connect another leg2 and leg4 with screw
Repeat Picture 1-7 to assembly 6 pairs of legs.
Step 6: Install Servo
Picture 1: servo and body
Picture 2: put the wire into the body hole
Picture 3: push servo into the body
Picture 4: screw up upper side
Picture 5: screw up with bottom
Step 7: Install Crankshaft and Legs
Picture 1: install axis1 into servo axis
Picture 2: install pair of legs into axis1
Picture 3: install axis2
Picture 4: install next pair of legs into axis2
Picture 5: install next axis2
Picture 6: install last pair of legs into axis2
Picture 7: instal axis3
Step 8: Install Paperclip Axis
align the leg1 and let the paperclip axis pass through the body and all the leg1.
Step 9: Test Run
Use servo tester check all legs run smooth.
Step 10: Install Another Side
Repeat steps 6-9 for the the side.
Step 11: Connect 360 Servos
Screw up the T-Journal mount and body with 8 screws.
Cut the 360 servos wire and soldering to the TTGO T-Journal. Left side connect to GPIO 2, 3V3 and GND; Right side connect to GPIO 4, 3V3 and GND.
Step 12: Install Battery
- Squeeze 2 Lipo batteries into the robot body front and back
- Screw up T-Journal mount, front and back with 4 screws
- Soldering 2 of them together in parallel connection to get a larger battery
