Helping robot dogs feel through their paws
Your dog has nerve endings covering its entire body, giving it a sense of touch. It can feel the ground through its paws and use that information to gain better traction or detect harmful terrain. For robots to perform as well as their biological counterparts, they need a similar level of sensory input.

Raspberry Pi-powered drumming booth with multicam recording
Back in 2019, Frank completed a DIY drumming booth for his son, Vik. While it did the job of reducing the noise coming through to the living room, the next part of the process was to make it a million times cooler by throwing several Raspberry Pis at it.

Helping robot dogs feel through their paws
TRACEPaw (Terrain Recognition And Contact force Estimation Paw) is a sensorized foot for robot dogs that includes all of the hardware necessary to calculate force and classify terrain. Most systems like this use direct sensor readings, such as those from force sensors. But TRACEPaw is unique in that it uses indirect data to infer this information. The actual foot is a deformable silicone hemisphere. A camera looks at that and determines the force based on the deformation it sees. In a similar way, a microphone listens to the sound of contact and uses that to judge the type of terrain, like gravel or dirt.
