Go Home Robot was created to mine "botcoins" during the 2014 ME210: Introduction to Mechatronics challenge. Using IR beacons and lines on the field of play, our robot needed to, autonomously, request coins from a server and deposit them into repositories. While we (narrowly) lost in the competition, our robot performed surprisingly well, given its short development cycle.
My focus was on the robot's hardware design. Laser-cut acrylic formed the basis for each level of the design, giving us the flexibility to refine component placement quickly and easily.
We also created a website to document our robot and its performance, which can be found here.
The Dragonsbock is a legendary bottle opener, renowned for its ferocious titanium teeth that render asunder the cap and bottle. Cast in bronze, it carries considerable weight, allowing it to also pierce bottle caps with its spikes.
It was made in Stanford's Product Realization Lab as part of ME203: Design and Manufacturing. In preparation for sand casting, a pattern board was made, combining additive manufacturing and hand sculpting processes.
The head was 3D printed using an SLA process, while the handle was cut and sanded from modulan. The two parts were married on the pattern board, yielding the final template for sand casting.
The raw castings were cleaned with a wire brush to preserve the sand-grain finish. A rasp also helped to deepen the texturing. Finally, holes were milled into which ground titanium "teeth" were inserted.
The Brewiken is a spiritual successor to the Dragonsbock. The first true assignment in ME318: Computer-Aided Product Creation, the Brewiken was inspired by Shurikens, but designed for more peaceful purposes. The outer blades allow for pry-off bottles to be opened, while the inner ring accommodates twist-off bottles.
CNC machined from a plate of 304L stainless steel, the Brewiken is durable enough for repeated use with steel bottle caps. The edges were intentionally left unbroken, as a small reminder of the Brewiken's inspiration.
My final project for ME318: Computer-Aided Product Creation, I designed Terrace with smooth lofts, but after seeing the finish post-roughing, I realized I liked it more. The object is simple; it's a light, but the machining marks reflect the light uniquely.
CNC machined from a block of 304L stainless steel, this part was a fun fixturing challenge, and resulted in many interesting arrangements to get various angles machined successfully.
The quickstart project in ME298: Silversmithing and Design, this ring represents an exploration into texture and unconventionalism. Starkly contrasting most rings, this one is highly geometric, but with an odd number of sides--seven. The lunar pitting leave a raw finish that is highlighted by the polished surface, leaving a design that resembles sunlight through tropical waters.
Originally carved from a wax cylinder, filing of the circumference resulted in seven faces. Rotary tools with ball burrs allowed for randomized pitting, which was originally planned as a hamemrtone pattern. Bead blasting cleaned the ring after vacuum casting, and the ring was meticulously polished by hand using jewelers' sandpaper.
Agni is the Hindu God of Fire. Created for ME298: Silversmithing and Design, this is a sculptural piece that captures, reflects, and radiates the qualities of fire. The color of the cast bronze feels warm, while the swirling spirals dance elegantly with the dynamism of a flame.
After sketching initial concept designs, a CAD rendering provided a template for carving a block of wax into a single "lick" of the flame. This lick served as a master copy through silicone molding. Wax is injected into the silicone mold, creating multiple copies, before being sprued to a wax tree and vacuum cast in bronze.
The base retains the hand-working of the licks of flame, but complements the hand carving with turning on a manual lathe to perfect the shape and lustrous matte finish.
The Haptic fMRI Interface is a research tool, developed in the Stanford Manips Lab and the Stanford Brains in Silicon Lab. It is a full, three degree-of-freedom haptic interface that is fMRI-compatible, so it can be used in conjunction with neuroimaging for experiments into human motor neuroscience.
Primarily constructed with rapid-fabrication parts (such as laser cut acrylic and SLS printed polyamide), it also makes use of other fMRI-compatible components in its drivetrain. Titanium shafts and carbon fiber linkages allow for torque and force transmission, provided by Faraday cage shielded motors.
