We have printed the parts that we made in the Solid Works and here are some pictures below.
We attached some rubber bands to our front legs to create friction so that the front legs can drag the body forward. However, we had an issue with the body. We needed some buttress on the bottom of the body piece for it not to fall backwards. There was no supporting piece to hold the motor upright. We, therefore, attached some red foams (as shown in the picture) to see if they help. They did help and we decided to make them in Solid Works, print them out and add to the bottom of the body. We also had some problem with the back legs (large legs). Even though they were balanced by having the hole in their center of mass position, they would fall backwards whenever they rotated. To improve on this, we decided to give some more weight to their lower parts to help on their stability.

Here are some newly designed model in Solid Works.
We created two new puzzle pieces (second picture) that would fit in the four new rectangular holes on the bottom of the body piece (first picture). We will have four pieces of ones shown in the third picture. They will fit into the two new puzzle pieces (second picture). This may sound confusing but the fourth picture illustrates it well. We also have created two holes on the back leg to give it some more weight and thereby easier and more stable in balance.
