I’ve just made a new video of MorpHex for demonstrating the rolling feature. One thing you may notice is that MorpHex rolls more or less in a curved direction instead of a straight forward direction. This is caused by the asymmetric design; the upper sphere section vs. the lower section. I’m about to get my hands [...]
To day I got some time to take some new photos of MorpHex. After my last post I found it necessary to some additional improvements, like strengthen the ribs on the lower sphere sections: The solution was pretty simple; just a little piece of PC glued to the rib and a 3mm nylon screw for [...]
When I posted the MorpHex part II video I cheated a little to make the upper sphere sections to operate as intended. The “cheat” was to use some kitchen rubber bands. As you can see from the pictures below the 5990 servo push the upper section out/upward. The rubber-band work like a spring and simply [...]
Sadly I've not had much time for robotics this year. But yesterday I finally got some time for shooting a video of MorpHex. I'm still not finished so there are still some features missing, like rolling. Hopefully there will be a part III video too. I'll post more details later with some pictures. In the [...]
The upper sphere sections are now mounted onto the hinge/linkage system. So today I took some more pictures with a darker background for better contrast, do I need to say more.. The camera lens is just for temporary support The "Nuclear shape": [...]
Its been a while since I last got some time for working on this project. But luckily I've had some time now and then for working on the upper sphere sections. I mentioned earlier that I'm using only six servos for controlling the six upper sphere sections. This mean that each sphere section only [...]
Hi, A new update about my MorpHex project. I didn't have time to take some good quality pictures because I'm working with some gardening and renovating stuff that occupies my "photo studio". Some workshop pics with bad lighting was my only option last evening/night. Anyway, I've been very eager to get the lower sphere sections [...]
Recently I've had to make a hard decision. I'm not ending the project, but there are some issues that has bothered me for a while. The fact is that I'm afraid MorpHex is just a little bit to heavy while being in sphere mode. Another thing is the wires, a total of 36 (x3) servo wires [...]
Its been awhile since I posted anything about MorpHex. I've not got much time for it either. Sadly this has to be a longterm project. Anyway, I just wanted to post some minor updates. I've added two decks (acrylic, I'm not sure to be honest) that are going to hold the electronics on one side [...]
Leg design To make Morphex being able to curl up into a ball shape, I've decided to go for a little special leg design. Actually, MorpHex is a sort of dual hexapod, where one leg share a common coxa part with two femur and tibia parts. I'm using standard SES brackets, but pay attention to [...]
