Project ShapeShift

This is a robot which can change it's shape. Yes It does! It looks like a regular car and changes to snake! It sounds weird but why not!

Similar projects worth following
This particular robot design can change its shape from a Robotic car to a robotic snake and back again anytime. The robot uses the special type of wheel design for locomotion called Mecanum wheels(an omni-directional wheel). This helps the robot to change its shape and navigate in both forms easily. This has a major advantage of transportation. the car can move to certain objects/goods and open up as a snake and swirl around the object and can use forklift to carry the object and drop at required location. We are working on making it swarm controlled so it can do individual work as well.

The prototype V1.0 shows that the proof of concept works.

A single servo was used to lock the wheel axle.

Version2.0 has 2 servos on the joint and 2 servos for lifting the object.

    V2.0 build log:

    Resizing the wheel to 60mm. We observed that the wheel was too small to have a ground clearance. So the wheel is being upgraded now.


    We are also planning to include 2 servos on the joints to control the wheel axle. This increases the stability and flexibility of the robot.

If you haven't patented this design, do so now.  Seriously, this is a great warehousing robot design.  Patent it so that you have some control over who develops it into a product.

  Are you sure? yes | no

It's already patented. We are working on making it a large scale prototype to make use in the industries.

  Are you sure? yes | no
