Intro
To practice building linkages and working with servos to control motion, I built a crab robot. Although it was meant to be a crawler, I was unable to successfully actuate the foamcore linkage to make the crab crawl across the ground.
Components Used
- Black Foamcore
- 1/8" diameter wood dowel
- Hot Glue Gun + Hot Glue
- Servo
I was not able to successfully hook up my crawler to the servo motor and actuate it through the Arduino, hence the lack of Arduino in "Components Used"

Crab Crawler: Rear View. The "H"-shaped piece synchronises the motion of the two arms.
Crab Crawler Detail: The four-bar linkage has joints made out of dowels that are hot-glued into one of the members at each joint.
