After two weeks of endeavor (sleeping in the lab etc...), I finally convinced the new InchBot to climb up a steep incline. According to the animal locomotion literature, climbing is defined as moving up a incline over 45 degree. Well, currently this InchBot-VII can handle just over 45 degree... so it's a climbing robot for sure!!
This 124mm long robot has two batteries in the head capsule and the rear capsule respectively. So it does not need to be tethered really. It weighed less than 4g if we include the R/C control circuits. It climbs with three sticky pads and several morphological features. The climbing gait was adopted directly from the principles of motion in Manduca caterpillar. Stay tune to my upcoming JEB paper titled: Substrate as skeleton: ground reaction forces from a soft-bodied legged animal for details.
Oh...this robot also got some pink sparkles in the body which made it kind of cute!
