Looking for feedback on a new 2 DOF hexapod design

LMAO, no silly

I knew that. Although it would be nice!

guess we’ll have to settle for an ultrasound image.

Range to target maybe?

While not necessarily revolutionary I have been experimenting with the tibia on this prototype 2DOF hexapod. There is a spring that allows the tip if the tibia to float while the hex is walking. The middle leg takes the brunt of the floating when the hex is walking forward, but the fore and aft tibias do more floating when the hex is turning in place.

The tibia needs to be made from aluminum, and I need to decide if the femur will be two plates or just the one. Trying to keep the costs down.

The chassis is now aluminum…

This has become a nice 2DOF hexapod, but to be honest it’s hard to muster any excitement for it when the multi-color 3DOF Phoenix is coming out, and the existing all-aluminum H3 line is killer.

For me personally, I would always get 3DOF if I was building a larger hex, so I don’t see a use for this bot. Maybe it is more appealing to folks on a tight budget who don’t want to buy 18 servos.

I have considered building a small 2DOF on a budget for my son (like your Mini kit), but this big 2DOF doesn’t have a niche in my world. Of course I may not be a typical customer.

Also, I don’t really get what’s going on with the “shock”. Can we see a pic of one dismantled?

This bot is going to be much less expensive compared to any of the 3DOF bots. Not only can it be made with only 12 servos, but it can use 12 inexpensive servos. So that’s the purpose of making it. The first hexapod I ever built was a 2DOF and I will always have a soft spot in my heart for them

The 2DOF leg moves the tip of the foot in an arc as it makes it’s stride motion. The shock allows the tip of the foot to make a straighter path. I’m sorry, but I just don’t have time to make a video of it today.

I like the design. It’s a great addition to the exsisting line of bots.

People of all sorts have varing tastes when it comes to the different plantforms available. Some like Sumos, some like Quads, or Hex bots, and some like the Bipeds, and still others like Rovers for all different reasons.

I totally understand. It’s definitely a great bot for the money. Are you recommending the HS-475 or something even less expensive?
