Flex Sensor Glove and Robotic Arm 

No, its scissors rock paper

No its paper, rock, scissors.

Thank you! It was great to meet you too!

Material is called velostat: www.adafruit.com/product/1361?gclid=Cj0KCQjw166aBhDEARIsAMEyZh5cESvl3jP675X6KDmSbky3oY--hQUT_Kh_EAG9bDCithGb0b-oCw8aAqPUEALw_wcB

@@WillDonaldson thank you so much will really helps

Sorry for the long response, hopefully it answers your question. In short: yes the delay can be removed! The delay can be seen in the first 15 seconds of the video when playing paper, scissors, rock, and around 4:50. The delay occurs because I programmed a minimum threshold before the robotic hand reacts. The main purpose for doing this is is to stop the fingers from jittering as the flex sensors are very sensitive causing continual vibrations. To make these scenes more aesthetically pleasing to watch I programmed a binary reaction (finger open or closed) by adding a minimum threshold before the fingers reacted. As a consequence there is a slight delay in reaction time. An alternative method for reducing this jittering would to be add a filter or signal averaging function to the flex sensor readings (this would also remove the reaction time delay), but I am pretty busy with other work at the moment so I decided just to take the easy way out (in hindsight it wouldn't have really been that hard to add a filter to the program and I probably should've just done it). It might be hard to spot as it happens so quickly but at 5:19 when the fist closes you can briefly see the thumb vibrating/ jittering, this is the effect I wanted to reduce.

Will Donaldson we are thinking to use flex sensors on the fingers, an IMU for the wrist movements on the forearm and we are thinking to use flex sensors on the upper arm (on the elbows and on the shoulder) We are just not sure if it is practical to use flex sensors on the upper arm instead of another IMU, as our mentor recommended the flex sensors for simplicity, we are not convinced with his suggestion. Can you please provide me with feedback on our situation. Best regards

We intend to use 6 DOF robotic arm that mimics our arm movements

With a gripper as an end effector

Similar devices are used in the medical field for rehabilitation (and more recently in VR too), however this specific project is definitely only at a hobbyist level. Here is an example of an FDA approved device that uses similar technology to what was demonstrated in my video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-E-0DF58FUDo.html&ab_channel=FlintRehab

I am not actively working on this project at the moment, but I may revisit it!

@@WillDonaldson Please do! This could be a very, very useful device for people to use!

I did not make the board myself, it is a device you can purchase already fabricated. www.sparkfun.com/products/13342 Be sure to share a video if you make your own arm!

Sure thing👍🏼

store the readings into arrays, then to replicate them just read the array and move the servos accordingly

There are definitely ways this could be adapted and improved. I encourage you to work on projects like this yourself and share them (as a personal preference I am more interested in robotic arms than VR). Here is a video on one of the leading VR gloves: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-OK2y4Z5IkZ0.html&ab_channel=SmarterEveryDay

you need one as a master and configure it to pair with the slave using AT commands. You can find detailed explanation of how to do it by googling "Pair two hc05 modules"

i've been looking for velostat for quite a while, do you have any idea where can i buy it from ?
